## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Best lift/$ ratio, hands down
  

*by P***T on Reviewed in the United States on September 11, 2020*

Insanely easy install, and the quality of the metal seems high. My only complaint is that the size of the bolts is a 9/16" instead of 5/8", so there was a little slop in the washers after install in a 1-ton Chevy Express. Otherwise, the finish is great and I expect these to last many years.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I will use this company again
