Proper LS3 installation

Converted to an LS3 water pump and balancer on my 5.3 LM7. This is the correct tensioner for the LS3 and is great for proper belt alignment.

Pros
  • Helps keep the drive belt at the correct tension for proper operation
Cons
  • Miscellaneous Miscellaneous

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

Every LS1/6 owner should buy this tensioner.

Works! This is a mandatory upgrade for LS1/6 engines. The tensioner on them tends to squeak (like mine) and the outer lugs aren't high enough, causing the belt to sometimes fly off on hard downshifts (happened to me and many of my friends). This LS2 tensioner fixes both problems, the big one being the higher outer lip.

Pros
  • Offers GM quality, reliability and durability OE
Cons
  • There are cons
