Suspension Enhancement Recommendation for 2017 Grand Design Reflection 5TH Wheel With Uneven Load

Question:

2017 Grand Design 337RLS Lippert 6000# axle. I would like to upgrade to 7000# leaf springs. I measured mine at 25 7/8inch loaded. I have 4 leafs. Would you have one that would fit. If not, would a 6000# 6 leaf be better. The trailer sets a little lower on the kitchen slide side. Also, would I need new U bolts? Thanks

The best thing you can do for your suspension on your 2017 Grand Design Reflection 337RLS is to add some jounce springs. The Overslung SumoSprings # SS26MV provide additional stability to your leaf springs. They will also help to reduce the amount your suspension compresses on the kitchen slide side due to the additional weight on that side of the trailer. You will need 2 of these kits for your tandem axles.

If you were to install 7,000LB Springs # e64SR your suspension will be stiffer and you get more bouncing out of the trailer. The additional bouncing will typically lead to issues inside the camper as more shock is transferred inside the trailer.
