1975-2026 E-350 SRW/DRW AlphaHD Pro S Rear Air Suspension Kit (HP10690-J-S)

Description

A loaded E-350 sits low in the back and drives like it. Pacbrake's ALPHA HD air springs add the load support the factory rear suspension never had, so the van or chassis stays level, tracks straight and stops wallowing over bumps when it is working.

Up to 5,000 lbs of load leveling capacity covers cargo vans, cutaways, box and service bodies and Class C motorhomes. Everything bolts on behind the rear axle with no vehicle modification.

This is the PRO S version: the air springs carry an internal flexible polyurethane bumper that stops the bag bottoming out if it loses pressure, and lets you run at 0 psi unloaded for factory ride comfort. Every fastener, fitting, valve and roll plate is stainless, and the air lines are braided stainless. Jounce bumpers do reduce bag travel, so if you need maximum travel for off road use, launching boats or dropping the rear to hitch a trailer, choose the HP10690 kit instead.
