Hello, dear friends! Today I invite you to consider with me and discuss in the comments the UAZ Trailer. This trailer is designed for use on UAZ 2151 vehicles, which previously had the index 469. This single-axle UAZ trailer is a good representative of its generation. It has one axis, so be sure to consider this before purchasing.
If you need a two-axle option, you can take a drawing and assemble a homemade trailer. Don’t forget, due to two axles the weight increases, reinforced springs are required and many other nuances appear. What am I telling you? Just read and compare two-axle and single-axle trailers.
Yes, today a huge range of all kinds of trailed vehicles are produced for cars. But you need to be able to navigate this diversity.
Selection and purchase
Someone decided to buy a car from conservation or simply use ads on Avito or other resources to find a used towed vehicle. The question of buying from conservation is quite interesting. That's the essence of it.
There is a military facility where vehicles were stored (mothballed) for a long time. This is not military equipment, since the army does not sell it to civilians, but vehicles that you and I can operate. Sales from conservation are affordable and in many ways profitable. That’s why people often keep special watch and find out where the sale will begin in the city of Astrakhan, or the Kemerovo region will announce the availability of vehicles for conservation.
You can easily find such advertisements yourself. Everything is sold there with documents, they offer reasonable prices and a number of other advantages. Although we may somehow talk to you separately about this. It seems to me that the topic of conservation vehicles, other vehicles and their sale will be interesting and useful for you.
UAZ has a fairly large number of vehicles in its product range. Let's name the most basic ones:
- 542;
- 3303;
- 3151 (469);
- Farmer;
- Hunter;
- Patriot.
The single-axle trailer itself from UAZ has the index 8109. It is not necessary to buy it for all the cars presented above.
For some craftsmen, it will not be a problem to use Krepysh trailers. Moreover, alteration of the hub is not necessary here. You can operate Krepysh with UAZ wheels and hubs, or with your own standard ones. Only in the second case will it be necessary to rearrange the hubs and increase the ground clearance, that is, ground clearance. There you go.
Materials
When selecting materials, it is necessary to remember that the trailer must withstand fairly powerful loads, while remaining as lightweight as possible. Therefore, it is worth paying due attention to every nuance in advance. Be also prepared for the fact that during the manufacturing process of the trailer you will need custom parts that will have to be specially ordered.
You should not take sheet iron with a thickness of more than 1 mm - this will not affect the strength, and the structure will be unreasonably heavier. Of course, it is desirable that during operation the spare wheels of both the trailer and the SUV are identical, so the hubs are needed specifically from the UAZ vehicle. The beam to which the hubs will be attached must be made of a thick-walled pipe or channel.
In addition to the above, you will also need:
- latch bolts with locking for the opening side (it is very important here that they cannot open on their own);
- springs with travel limiters;
- rectangular profile pipe about 30 m long;
- a piece of pipe about 20 cm long (for making a stand leg).
The role of the drawbar will be played by a pipe with a wall of at least 5 mm, its length should be 2 m. For safety reasons, you need to equip the drawbar with a safety chain - in the same way as in the factory version. To make the trailer tall and make it easier to maintain the gearbox, you can use a bridge as a beam.
This method is also good because you don’t have to look for mounts for springs, hubs and shock absorbers.
Design features of UAZ 8109
Let's start with the description of the UAZ trailer we are considering. You can watch a video about it, look at various photos to better understand what we are dealing with and what I am talking about in general.
And for those who are not interested in buying a ready-made car trailer, there are a number of useful recommendations on how to make a car trailer with your own hands. If so, just follow the links and read. Next, be sure to read about trailer registration issues.
What do we have in the case of 8109? Let me first offer this description:
- The trailer is made of a frame based on durable metal. The metal platform is welded to this frame;
- The 8109 has a tailgate that greatly simplifies loading and unloading procedures;
- When the load is placed on the loading platform, it is positioned so that the vertical force from the coupling loop to the towing hook does not exceed 490 N or 50 kgf;
- If you intend to operate a trailer without connecting it to the vehicle with a safety chain, forget about your intentions. You can't do that;
- The welded frame consists of a pair of side members, a drawbar and cross members;
- A pair of towing hooks are installed on the rear of the frame;
- The drawbar has a welded structure and is integrated with the frame;
- A removable hitch loop and safety chains are mounted on the front of the drawbar. We read separately about the features of the coupling device;
- In a horizontal position, folding support posts are used to hold the drawbar;
- To attach the coupling eye to the drawbar, use a connection using 3 bolts.
This concerns design features.
Next we move on to the technical parameters. There I will tell you about the main figures that relate to the UAZ 8109 car trailer.
Popular models of trailers for UAZ
The well-known UAZ-8109 is the basic prototype of trailers for cars produced by the Ulyanovsk Automobile Plant, the progenitor of its subsequent modifications produced by enterprises throughout Russia. One of the popular trailers is still the predecessor of the above-described GAZ-704 device. It was taken off the market in '98 but is still in use today. As for modern models for UAZ vehicles, the most popular are:
- Universal. Designed for transportation from bulk to large-sized cargo, suitable for any SUV. It is equipped with tractor wheels.
- Fire monitor. Equipped with a powerful winch and used when transporting equipment.
- Spring-loaded. Less load-bearing, but suitable for jewelry work such as transporting fragile cargo.
- Biaxial. Used to transport long, heavy loads such as a boat.
- Other samples are no less popular and are selected by the car enthusiast in connection with the task at hand.

Specifications
When the vehicle is equipped with a load of 500 kg, the total weight is 750 kilograms;
The permissible maximum cargo weight for transportation on 8109 will be 450 kg;
The equipped trailer together with the awning here is 300 kg.
Now about the distribution of road loads through the wheels of trailer 8109:
- at full weight the figure is 750 kgf or 7357 N;
- with the vehicle equipped - 270 kgf or 2649 N.
No less significant for some buyers will be the value of the forces from the coupling eye to the towbar:
- for a trailer with a full weight the force will be 490 N or 50 kgf;
- for a equipped vehicle the indicator will be 295 N or 30 kgf.
If you decide to attach such a trailer to your car, then you are allowed to accelerate with it no more than 75 kilometers per hour. But who actually follows these recommendations?! Remember, this is purely a matter of your safety and responsibility to other road users.
If you are interested, I also suggest telling you about the lighting of this single-axle UAZ trailer.
Suspension
The UAZ car trailer with index 8109 uses two longitudinal semi-elliptical springs, which work together with a pair of telescopic hydraulic shock absorbers.
The spring includes 9 leaves. Their ends are mounted using pins and rubber bushings. One spring has a length of 1000 millimeters with a sheet thickness of 45 millimeters.
Installation of accessories
Now it's time to work on the wings and mudguards. High fenders will prevent the wheels from blocking due to accumulated dirt. This factor is very important for the safety of cars behind - if the wings are not high enough, dirt will quickly cover their windows. It’s up to you to buy wings ready-made or make them yourself, but it will be great if they turn out to be as strong as possible.
Lanterns should be installed on the sides of the sides so as not to inadvertently break them during loading operations. Brackets are required for the lights, and it is recommended to protect them with a grille, again to avoid damage. Some people prefer to install an additional fuse box in the trunk, but this procedure is not necessary.
Before starting electrical work, you need to purchase, in addition to flashlights:
- corrugation to protect wires;
- the wires themselves are of the required length and thickness;
- a reliable socket for communication with the on-board system.
After all the procedures described above, all that remains is to build the tent. For this purpose, brackets are welded to the sides, into which frames will subsequently be inserted. The spare tire can be attached to the front side, to the drawbar or under the bottom of the trailer. Don't forget to paint all the metal parts of your piece - this will help avoid the ever-present corrosion.

The shock absorbers here are of a double-acting type, telescopic and hydraulic. They were unified with the shock absorbers of the 3151 car from UAZ. You do not need to make any specific settings and adjustments.
The wheels are stamped and made of steel. The rim is deep and one-piece. Their dimensions are 6Jx15. And the tires are six-ply tube type, size 215/90 and R15. The manufacturer tried to unify the trailer hubs with UAZ 3151 car hubs. Although some people like to deal with wheels of a larger radius. It's a personal choice for everyone.
When adjusting the torque of the hub bearings, be sure to carefully control it. It would be a good idea to take a suitcase with tools and get a torque wrench. If you do not tighten it properly, the trailer will be subject to constant impacts during operation, which will cause the bearings to fail in a short time. If you tighten it too tightly, then the bearings will begin to heat up excessively, all the lubricant will leak out and the bearing will become unusable.
Electrical part
It's no secret that to connect a trailer to a car you will need two main electrical components:
Trailer service
A trailer for a UAZ vehicle requires attention and care:
- To minimize the effects of corrosion on parts, the unit is stored in a dry garage. If there is no space in it - in the open air under a waterproof awning or canopy. It is worth remembering that the body is primarily susceptible to corrosion due to its structure.
- After use, the trailer on the UAZ is washed and cleaned of dirt that has clogged into the joints of the parts. Cleaning your trailer will help prevent early rust.
- The condition of the wheel hub bearings is periodically checked and lubricated as necessary.
- Overload contributes to premature suspension failure.
- The condition of the light signaling and electrical wiring contacts is monitored.
- Much attention is paid to the shape of the coupling device, since when operating a road train with a worn-out coupling mechanism, the skidding and turning radius of the vehicle increases.
- When the unit is idle for a long time, a stand is placed under the supporting beam of the unit so that the wheels do not touch the ground.
- The outlet is monitored and must not come into contact with water in any way.
Video review of the MZSA trailer model Off-Road 817701.016
The UAZ vehicle, having traction characteristics characteristic of the SUV family, is capable of pulling any unit from the Kurgan “Krepysha” to heavy carriages. It is not afraid of snow or dirt and, when coupled with a trailer, forms a worthy road train.
Modifications
Depending on what kind of cargo will be transported on the trailer, its modification is selected.
If you plan to transport long and heavy loads, such as a boat, then you will need a trailer with two axles. It is not suitable for off-road use, therefore, when going on a trip, you should think through the route in advance and exclude problematic sections of the road from it. In addition, such a trailer obliges the driver to have an open category “E” license, since the total weight will exceed 750 kg.
If you plan to use the trailer in a fairly wide range, for example, for transporting bulk cargo, it makes sense to purchase a dump trailer. This is a universal modification with a wide range of applications. Manufacturers often equip such trailers with a winch with a load capacity of up to 550 kg. This addition makes it possible to use a dump trailer to transport an ATV. A winch will make loading it into the body much easier.
A single-axle trailer for UAZ, based on the 8109 model, is quite suitable for transporting small loads.
For all modifications of trailers, the manufacturer provides for the use of a waterproof awning, which will protect the cargo from wind and precipitation.
