Best SumoSprings For 2015 GMC Sierra 2500 With Light Camper & Towing Trailer

Question

Question:

Hi looking any sumo springs and wondering what one to get. I have a 2015 gmc 2500 6.6 diesel paired with a 1800 lb cab over camper towing a 8000 lb wakeboard boat 2 axle trailer. Not sure tongue weight? What would you recommend. Camper comes off during the week. Thanks

Expert Reply:

Since your camper is relatively light, and it comes off during the week, the mid-duty SumoSprings are going to be the best option for your 2015 GMC Sierra 2500:

- SumoSprings Rebel Custom Helper Springs # SSR-203-40-2

The # SSR-203-40-2 have a 3,000 lb capacity so they will still provide your Sierra with the support needed when towing with the camper but without degrading the ride like the stiffer 5,000 lb # SSR-203-47-2. SumoSprings were a really smart choice for your truck as they'll take the brunt of the weight put on your truck's rear suspension to counteract sag, helping level and stabilize your truck for smoother handling.
