Customers commend the product for its exceptional quality and easy installation process, even with basic tools. The parts are reported to be of high caliber, with excellent fit and finish. Several users appreciated the fact that the kit included all necessary components. Some highlighted features include tubular control arms, coil overs for accurate control arm alignment, and the ability to customize color on raw steel parts. There was a particular appreciation for the polished coil overs and chrome springs, and the adjustable ride height. A couple of users remarked that rubber front brake lines were provided instead of preferred braided lines. Overall, users recommended this product over competitors due to its superior features and value for money.

I bought this kit for my 54 F100. everything fit as it said it would. I bought the kit with the standrd spindles and swapped them out for the 2" dropped after I installed the kit to see the ride height. No hassel at all.
