Question

Question:

Hi, Which Sumo Springs do you recommend for the front and back of a 2022 Thor Freedom Elite 30FE class C RV on a Ford E-450 chassis? It is 32 feet long I have gotten different responses from other places about using blue vs black in the front and yellow vs black in the back. Thanks.

I checked with SumoSprings and they recommend the black springs, so the SumoSprings Solo Custom Helper Springs part # SSF-106-47 for the front and the SumoSprings Maxim Custom Helper Springs part # SSR-106-47-1 or the SumoSprings Solo Custom Helper Springs part # SSR-130-47 for the rear on a 2022 Thor Freedom Elite with Ford E-450 Chassis.

Please note, if you have lines or anything on the outside of the frame, above the leaf springs where the Maxim will mount, you'll need to go with the Solo.
