Best Suspension Enhancement Recommendation for 2021 GMC Sierra 2500HD

Question:

Hi, Just bought a 2021 GMC 2500HD SLT short bed/crew cab w/ Duramax. I put a smaller travel trailer 21 ft. 4500 lb dont know tongue wt. and it sagged a 1 1/4. The truck sits level and I have tried any of my larger trailers w/ heavier loads yet. What do you recommend in keeping the truck level plus the other factors. Maybe the other factors dont matter as much since I will be pulling more than putting weight in the bed. I look at the Timbren, Torklift, Air bags and now this. It gets a little confusing. Thanks

The RAS systems like what you asked about are the best all-around suspension enhancement for your 2021 GMC Sierra 2500 with the part # RAS3611-HD for if you do not have the factory overload springs or the # RAS3611-CHD for if you do. This kit unlike other options gives you the support you want without any compromises. Other kits will affect ride quality (loaded and unloaded) whereas this actually improves ride quality. It's also easily adjustable, installs easily, and also acts almost like a sway bar to improve stability so all-around you really can't beat it.

The air bag kits are somewhat of a hassle to deal with and the rubber spring options are just harsh all around.
