First you will want to check your 2,800lb SumoSprings Solo Custom Helper Springs # SSR-313-54 to determine if 2nd 1" spacer was installed with the springs. If you have both the 1" spacers you will want to remove the 1" spacer which doesn't have the pressed in nut. This will help to reduce how much the spring compresses under a normal load. As the spring is progressive it will reduce how stiff the spring is and help to smooth your ride.

If you are still finding the ride is to harsh you will want to consider going down to the 1,500lb SumoSprings # SSR-313-47.

@Wayne Since you do not have the 1" spacer on your current 2,800lb SumoSprings # SSR-313-54 you are going to have to swap them with the 1,500lb SumoSprings # SSR-313-47 to smooth out your ride.

@Wayne Same exact issue I have. Did you swap the Sumo springs out? If you did, did it help. Pam
