Timbren or SumoSpring Recommendation for 2021 Ford F-250 with Camper
Updated 10/22/2025 | Published 04/08/2025
Question:
Hi. I have a 2021 F250 SRW Currently I have the upgraded bilstein socks, added a leaf to the stock spring pack, hellwig helper springs and hellwig swaybar. My main issue right now is rear sag when loaded with my ~3,500 slide in camper. The ride quality is sufficient with my current set up, just need to level it out when loaded. When loaded my rear end s about 3.5” Given this information, should I go with the sumo springs or the timbrens and which model? Thank you for your help. Greg

Hey Greg, I would recommend the SumoSprings Rebel part # SSR-128-47-2 for your 2021 Ford F-250. This gives you a lot of support like you are wanting as well as offers a better ride quality than the Timbren setup so it's for sure the way to go.
