Reviving old thread!
Old thread, I know!!
But I installed a set last night on my Tahoe. After cranking the front torsion bars to help clear my 33's, the truck sat level, but then the rear end would squat with much cargo or when towing a trailer. I didn't want to install a full lift kit or use lift blocks, and I wasn't crazy about using an add-a-leaf, so I decided to give this product a try.
Installation is super easy, especially with the new design as was mentioned. You can choose from two settings on the coil tension. With the lightest setting, I gained 1" of lift when empty, and now the rear doesn't sag when loaded or hooked onto a heavy trailer. So far I'm really pleased! The ride seems great as well.
I'll keep ya'll updated on how they work out, but I definitely would give them a hard look if you need a little lift or extra load-carrying capacity.
