We Custom make leaf spring coil assisters for Campers,Motorhomes & Vans.
The best solution to worn leaf springs and a sagging rear.
This is our own Registered Design owned by Custom Campers UK.
If your motorhome, camper or van suffers from rear end sag, Custom Campers have developed an assister that will lift the back of your vehicle. These are a very heavy duty pair of coil springs fitted between the axle and chassis. They are not like other brands. These will not wear, break or weaken. Fitting can be done by ourselves or customers can fit the kit themselves. We do supply a D.I.Y kit but they are custom made to fit your vehicle so they do need someone who knows what they are doing to fit them. These will fit Talbot Express, Ford Transit and Bedford CF and more. Please see photos below of before and after, these are fitted to my own Talbot Express motorhome.
Please read everything on this page as it will answer a lot of questions you may have regarding spring assisters.
Motorhomes& Campers.
The rear end of motorhomes and campers do suffer with the weight of all the equipment on board, the vehicle and leaf springs were never designed to have the constant weight sitting over the axle. The reason for the leaf springs weakening is that the vehicles were originally a commercial vehicle and loading and unloading of weight would not have been constantly over the axle. If you have any questions please contact us.
LGV. Vans
Sometimes when a van is fully loaded to it Maximum weight the rear can look very saggy and over loaded. With spring assisters they will keep the rear end at a reasonable height and the drive will be much better for long distance deliveries. They do not make the vehicle carry more weight over the legal weight loading of the vehicle. If you have any questions please contact us.
Recovery Trucks and Transporters
If your truck is a home conversion or from new, again the leaf springs wear and with the centre of gravity being higher up due to a car loaded on the rear it can feel unstable. When our kits are fitted to a Car Transporter the ride will be quite ridget when empty. But when loaded it will sit roughly at the height when unloaded. If you have any questions please contact us.
Horseboxes.
When the horsebox is empty there is less weight constantly sitting over the axle, but when loaded and if the leaf springs are weakening, again this can feel unstable. If you have any questions please contact us.
Why Coil Assisters and not fit new leaf springs?
After years of research designing our assister kit I came to the conclusion that coil spring assisters were a much more economical way to go than replacing leaf springs. I will use my own motorhome as an example: To replace both leaf springs with new heavy duty springs, (bear in mind there's no point in replacing with the same load rating springs or you might as well do the job again in a few years time) proved expensive. The heavy duty leaf springs were priced at £435 each (2009 prices), fitting them could be tricky as bolts need to be replaced as you can bet they would snap or wouldn't move. U bolts have to be replaced with new at £60 a set. I added the cost up to replace the leaf springs at around £1,100. Following this research I then designed our coil spring assisters which are less than half the price and easy to fit, thus solving the problem and proving you do not need to fit new leaf springs.

Custom Campers
UK has been trading now for some time. We repair and restore campers &
motorhomes. Our main website is
In 2008 we designed and developed a coil spring assister that could be fitted under a motorhome to help with weak leaf springs. In 2004 I bought some spring assisters from a company which didn't do the job very well and after two years and after 15kmiles I discovered 3 of the 4 springs had snapped. I decided to design and custom make a kit that would not weaken, snap or have to be replaced in a few years. I fitted my first coil assister kit on my Talbot motorhome in 2006, I did two years of touring and all was ok, no faults at all. But I always knew I could make the kit better so in 2008 I fitted a new design kit. its now 2022 and I still have the motorhome and the kit is still fitted with the same springs and still sits at the same height it did in 2008.
Our kits are very strong and can be quite heavy (27kgs) but they are made to last, Please see the photos on the video page to show the size of coil springs we use compared to others. One customer commented that they would see out the life of any motorhome. If you decide on the D.I.Y kit, the kit comes with full fitting instructions and can be fitted within 4 hours. Tools needed are 17mm & 10mm spanner, two trolley jacks & a 10 & 6mm drill bit. Everything else is pre drilled and ready to be bolted into place.
Our kits include.
2 x coil spring max load of 700kgs each.
