Overall Assessment

The product, a lowering block kit, is highly favored by customers for its quality, affordability, and ease of installation. Users have successfully installed it on a variety of vehicle models, notably vintage cars and trucks. The robust build and appropriate sizing of the blocks and U-bolts are repeatedly praised, with many customers remarking they would buy the kit again. Some customers found the U-bolts overly long or wide, leading them to adjust car holes or trim the bolts. Nevertheless, the kit reliably enables desired vehicle lowering and improves the stance and look of the vehicle. A few users suggest the kit could be improved with customized bolt lengths to fit specific block sizes for easier installation. In conclusion, this is a well-made, practical, and cost-effective solution for lowering cars, recommended by its users.

Worked as advertised

I have used lowering block kits in the past. They work great and are easy to install. A humorous thing happened this time. We installed the kit and lowered the car and it did not set any lower than before.(????) How could this be? We had not noticed that when we had the car on the lift the rear shackles had flipped. This offset the lowering effect of the blocks. It took awhile before we figured it out. We felt a little silly.

I would not buy this product again for my application.

my springs are 2 inches wide and the lowering blocks are 21/2 inches wide.they cannot be narrowed because they are a hoolow casting.. Therefor they are not universal. I did utilize the longer u bolts and made my blocks out of 2x2 sqaure tubing.
