Rear Suspension Enhancement Recommendation for 2018 Coach House Platinum 3
Updated 07/06/2026 | Published 06/23/2026
Question:
I have a 2018 Coach House Platinum 3 class C motorhome which is built on a Ford Transit 350HD. The heavy load causes the rear to sag. I would like to replace the rear bump stops. What product would you recommend

Hey Darrel, we have the Hellwig EZ-990 rear suspension enhancement kit part # HE32VR that is a confirmed fit for your 2018 Coach House Platinum 3 that is a Class C built on a Ford Transit 350HD chassis. This would do an excellent job eliminating the sag you are experiencing and this actually doesn't remove the OEM bump stops.

Timbren H/D longer bump stops works GREAT making contact all the time with no squat. Our OEM rear sway bar on our T350HD DRW Van helps sway tremendously. Rides, Drives & Handles Wonderful.
