Rear Suspension Enhancement SumoSprings For a 2017 Jayco Greyhawk With Factory Helper Springs  

Published 07/17/2021



Question:

I see that it says they will fit on the Rear. But with the factory JRide system its not possible. Are you suggesting removing the factory Hellwiginch helper spring. If so, does that mean that the SumoSprings offer more support than the Hellwig. Or was that a typo as far as them fitting the Rear Greyhawk.

Expert Reply:

I recommend leaving your current factory helper springs in place on your 2017 Jayco Greyhawk 29MV. The SumoSprings Solo Custom Helper Springs # SSR-130-54 would be the additional enhancement that will help with your ride quality. These springs offer a progressive spring rate where the leaf springs are not progressive. So as these compress they will get firmer the more they compress, this helps them to act as a shock absorber as well.

The SumoSprings Maxim Custom Helper Springs # SSR-106-54-1 while they are not capable of working on your specific Greyhawk will fit models that did not include the factory helper springs and will also serve as a replacement for those springs. The two different systems offer support in different ways and some may choose the progressive springs over the Hellwig style.
