Van Compass rear add a leaf spring pack, 4x4 Sprinter 2500.
Used for a couple of months and replaced with full new custom spring pack because I was exceeding GVWR with tongue weight of trailer.
From the Van Compass website: As a vehicle approaches its GVWR (Gross Vehicle Weight Rating), the rear suspension will naturally begin to sag and ride quality will begin to suffer. The Sprinter van is no different. This multi leaf spring pack installs under the factory leaf springs and can increase ride height from 1" to 1.3" (25mm to 33mm) depending on the vehicle's weight distribution. The increase in spring rate gained by this leaf pack along with the additional clearance between the bumpstop and axle will reduce the chances of bottoming out, enhance vehicle stability, ride comfort and restore the factory look of the van. This product is designed to improve ride and handling while at or near GVWR, however we do not recommend exceeding the manufacturer's GVWR.
