Hey George, thanks for reaching out. Yes, that’s exactly where the SumoSprings Solo # SS49PJ really shine. They replace the factory rear bump stops and provide 1,500 lbs of support at 50% compression, helping reduce rear-end sag, body roll, and bottoming out when you load the Grenadier with camping gear, recovery equipment, tools, or other heavy cargo. The progressive design gets firmer as the suspension compresses, so you get more support as the load increases without turning the rear suspension into a rock.

I also like these for a Grenadier because there’s nothing to maintain. No air lines, compressors, or pressure adjustments, just install them and let them work with the factory suspension. They also help control side-to-side movement on rough roads and uneven terrain, which makes them a really nice upgrade for a vehicle that actually sees some off-road use.

What do you normally carry in the back of your Grenadier, camping gear, recovery equipment, or something heavier?
