Renault Taffic Mk1 is a different kit to the Master model. The Master / Movano Mk1 is a different kit to the Mk 2 and Mk3 After some years of having the weight sat over the rear of these vehicles. The leaf springs start to bend the opposite direction to the way they should. With this kit there is no X member, the kit slots onto the chassis directly above the axle. Please see video page for photos. For information please visit the "Home & Info" page.


Please note, if your unsure you have a Mk2 or a Mk3, the Mk2 has a round axle and the Mk3 has a square axle.

This is our own design owned by Custom Campers UK. If your Renault motorhome,camper, van or recovery truck suffers from rear end sag. Custom Campers UK have developed an assister that will lift and impove ride. These are a very heavy duty pair of coil springs that fit in between the chassis and axle. They are not like other brands. These will not wear, break or weaken. We supply this kit as a D.I.Y kit or we can fit them for you. I have the same kit fitted to my Talbot motorhome which are over 3 years old now.

We offer a fitting service here in Cheshire. However if we are too far away from you why not check out our fitting agents list to see if there is a fitter near to you. You will find this list on the "Fitting Agents in the UK" page

As you can see we use very strong coil springs compared to others. Each coil spring kit is rated at 900kgs ,1100kg or 1400kg depending on your vehicles needs.

This photo was taken before the kit was fitted. The leaf springs are bending the oppisite direction.

This is after the Spring assister kit was fitted to my Talbot. As you can see it fits between the axle and the chassis. Note the correct bend in the leaf spring now.

Our kits include.

2 x coil spring max load of 700kgs each.

4 x coil cups

1 x cross member(Talbot/Boxer/Relay/Iveco/Mercedes Sprinter/crafter. only)
