Question: Good day. I have a 2021 Grand Design Momentum, 353G, with 7k Dexter Axles installed. DEX#: 9625074 PO:011-489589 I am concerned that the leaf springs are looking kind of flat. I am looking to replace the leaf springs. Can you help with the correct replacement leaf springs i should replace with?

Expert Reply:
First I recommend the SumoSprings Trailer Helper Springs # SS26MV be added to your axles. As these are designed for a single axle you will need 2 of the kits. It seems strange that the springs would be damaged as they are not that old and are likely carrying a lot of weight. These helper springs will help relieve some of the weight and provide some additional support to your leaf springs. As they springs are progressive they also help to reduce a lot of the shock that is transferred through the suspension into your 2021 Grand Design Momentum 353G.
While we currently do not carry your leaf springs 072-098-02 or a equivalent replacement, we do carry any additional hub/brake parts you may need for your Dexter Axles.
