These springs replaced the rear springs in an 03 suburban that was several thousands of pounds overweight.These, along with a set of coil over spring shocks, easily restored factory ride height, and factory handling.

These springs are perfect for a very heavily loaded vehicle with air suspension. The air system would time out on us when we loaded down our yukon with tools and guys and bounce all over there springs raised the unloaded ride hight 3 inches but with the 1000lbs of tools and 4 men we ride just about normal hight and no more bounce.Update 6 months in about and springs are working perfectly heavy towing with family or friends and never a issue

As described, HD springs were direct install, much heavier duty than my 21 yr old stock springs. Yes it does lift my rear end, but I have no doubt will do the occasional tow/load when I need it. (Last tow I was hitting bump stops). Very happy with the purchase, fit & overall results. Wouldn't hesitate to do it again.

They went in easy. Raised my rear end about 2 inches with the use of Monroe coil over shocks.

Springs arrived fast. Perfect figment for my 07 Suburban which had the rear sagging. Restored the rear height. Would recommend.

Installed on an 07 yukon xl being set up as an Overlander. The extra weight had the bumpstops just touching the stops. Tried airbags in the original coils, did not achieve the desired results. These springs returned it to original ride height. Ride great, not harsh. Exactly what I needed. Very happy.
