Useless Junk! Waste of Money!

Based on my experience this product is absolutely terrible .The installation process was a nightmare and it didn't improve my car's braking performance at all. It didn't even maintain the performance that my car had before..

Pros
  • None
Cons
  • Didn't improve or maintain performance

Wrong steels included

Part quality as expected. The problem is that the steels included in the kit are for TH350 and not TH400. I had to build a gearbox out of old steels. I didn't have time to wait for Revain to fix the issue. The truck should be back on the road before the weekend.

Pros
  • Steel plates are precision sized for seamless installation and vibration free operation
Cons
  • Transparency
