Rear rides lower than front axle on 170WB 2500 Conversion

Hi everyone,

The rear of my van rides significantly lower than the front, almost 2" at the wheel well. It's a conversion I built myself, it weighs almost 9,000lbs so it's possible the rear is heavier. I did replace the front struts when buying the van at 185k, but not the front.

Will replacing the back struts help with the ride height? Does the ride height really matter outside of aesthetics? Is there another way to fix the problem?

Thanks very much in advance for your help. Cheers, Joe.

The 'back struts' are actually the shock absorbers and have no bearing whatsoever on the ride height of the rear of the van. They merely control the bouncing and rebound when going over bumps. To change the ride height you will have to replace the springs.

But first, what is the weight on the rear axle, I strongly suspect you are overweight by the figures on the VIN placard on the drivers seat base.

Joeywestside,
Is your 170" (4325mm) an extended rear body 2500 (316/319 series) Sprinter?
The EXT (Extended rear body/rear overhang) puts weight well behind the rear axle
and this can easily overload the rear springs.
As suggested, a trip across a truck scale and a careful look at the weight on the
rear axle, compared to the allowable rear axle weight on the placard on the side
of your driver's seat box (also on the "B" pillar) will quickly tell you if you are
overweight in the rear.
Running overweight on the rear axle is definitely not a good idea.

Sounds like you should contact a Sprinter suspension specialist, depending on where you live.

Here in Socal we fortunately have Agile Offroad.

The Pacific Northwest has Van Compass. There are some other Sprinter specific outfits in these areas that are worth checking out.

If you let us know where you are, there are members here who will help you find a reliable resource to help your suspension concerns in your area.

Years ago, I stopped at an interstate truck weighing station so I could know where I was at. 8100 lbs. total when mostly empty.

Roger, as always, recommends weighing your front and rear axles. Take that to heart. Then you can address your springs tolerance for whatever weight you end up carrying.

I have always wondered about my 06 Freightliner 2500's factory single rear spring being enough. I did add a set of rear passive helper springs years ago when I towed a trailer across town and the springs sank dramatically down to the pavement with the weight. These helper springs only come into effect when the load is heavy. The rest of the time the ride is as comfy as originally designed. I knew better than to add more springs which would have made for a rougher ride. These passive setups worked for me. To each his own.
