Review on πŸ”§ ACDelco GM Original Equipment 12569301 Drive Belt Tensioner - Reliable and Long-lasting Automotive Component by Thasapon Keitt

Revainrating 5 out of 5

A nice upgrade from the stock LS1 tensioner

I have an LS1 engine and the belt kept jumping over the lip. I didn't have that problem with this tensioner. Probably a combination of needing a new and higher lip.

Pros
  • Manufactured to GM OE specification for fit, form and function
Cons
  • Available in white only
