Heavy Duty Leaf Springs & Shock Absorbers

Hi. I own a Bessacarr E560 and have an issue with the rear suspension or lack therefore off. It seems that the leaf springs are no longer springy and the van is sat on the bump stops. Ive also got a blown shock. Should i be looking to replace with standard Fiat Ducato equipment or does a motorhome require uprated/heavy duty equipment? Im just concerned that if i install standard parts that the issue will be just the same.

Most cities have small businesses which will make and sometimes also fit springs. I'd find one of those and go and have a chat with them.

Here's an example: https://www.jones-springs.co.uk

Google truck spring makers in your area.

The "bump stops" you refer to are not what you think, they are actually part of the suspension system and it is normal for them to be in contact with no obvious gap between spring and rubber bellows.
If you do a search you will find that many have misinterpreted the design of this base vehicles suspension.

A readily available and easy fix to a sagging rear end is to use pneumatic suspension assisters.

Standard shock absorbers should be adequate but replace both not just the one that has failed.

the first thing i would do is get the van weighed as you need to know the weight on the rear axle

not knowing how many miles your van has done and the condition of the springs it is hard to say but air springs will help a lot but if your rear springs have sagged a lot the air springs might not do all you are hoping for

so firstly down to the weighbridge, i think you need to see where you are weight-wise to weigh the rweight on the rear axle by driving so that the front wheels are just off of the bridge and then do the same for the front axle

this would give you a good indication as to where you are weight-wise

let us know what the weights are and we can advise from there barry

Shock absorbers are in fact far better described as dampers.
They absorb next to nothing but restrict the rebound from a spring. They offer some, but not very much, resistance when being compressed and a lot of resistance when being extended! (Unless they are knackered that is)

Sound advice from Powerplus, you may well be very surprised/horrified/uncomfortable/shocked at what you discover!


Its not the destination that matters.

It's who you share the journey with (even if like me, its in a caravan!)
I am very fortunate to have Mrs Plodd to share mine with
