Product went on very easy and looked to be of good quality. I’ve hauled a lot lately and it really does help with the squat of the truck.

Lightyears better than helper springs
These are so nice, and so much better than helper springs for one main reason. Helper springs give you a stiffer ride at all times, and thus allow you to carry a little more payload because you have more spring. These on the other hand actually improve your ride quality when unloaded, and they are progressive so the more payload you have, the more they help. This enables you to keep a consistent ride height in the rear without getting a huge lift when unloaded and unloaded like helper springs do. I wish I would've done this on my last truck instead of a helper spring!!

Perfect
Perfect fit. Had to persuade the bolt under the leaf spring to fit between block and the bolts from the bracket only because I have a lift kit on the truck. Easy mod.

I put the this on my 2021 Silverado 1500 at the max setting and it is a night and day difference. The ride is just ad good as before when unloaded, and with a heavy trailer is way better. I hooked a 30' travell trailer to the ba k and it just brought it to be level. At max it will raise your rear 1.5 inches
