Expert Reply:
For your Grand Design there are 4 choices of SumoSprings Trailer Helper Springs. First you will need to determine if you have overslung or underslung axle. Overslung will have the axle mounted below the leaf springs, underslung will have the axle mounted above the leaf springs. Next you will need to determine the weight capacity of your axle. This is typically on the information sticker at the drivers side front of the trailer.
Overslung 3,000-5,000LB Axle # TSS-107-40
Overslung 5,000-8,000LB Axle # SS26MV
Underslung 3,000-5,000LB Axle # TSS-106-40
Underslung 5,000-8,000LB Axle # SS33HR
For an overslung axle you will need 5-5/16" to 6-1/2" between the U-bolt top plate and your frame. The underslung will need 7-7/16" to 8-5/8" from the top of the leaf spring at the axle to the frame.
