Question:

I have a 2021 Chevrolet Suburban and when trailing and distribution hitch I get lots of rear suspension squat, is there a product for the rear suspension like the air bags for this model, I believe I have coilover suspension?

While I do not see any aftermarket rear suspension enhancement confirmed to fit your 2021 Chevrolet Suburban I may be able to help you find one. SumoSprings just verified their Helper Springs # CSS-1168R to fit the new Tahoe body style. You can confirm if these will fit your Suburban by measuring your coil springs. These were designed to fit a coil spring with a 6-1/4" inner diameter and 3" height between the coils. If this matches your Suburban they will also work for you. Otherwise please let me know what measurements you have on the coil springs and I can see if there is another option.

Bud, my 2021 Suburban seems to have rear coil springs inside diameter closer to approximately 5" inside diameter. It is a 2021 High Country. Is there an option for something with a smaller inside diameter? (I am surprised the Tahoe which this DOES say it fits, has 6.5" inside diameter coils while the same year Suburban has 5". That doesn't seem right.)
