TFS Performance Valve Springs for Domestic V8s

In stock
Product Details

We are blowing out these kits so you can blow up your competition.

Mamo Motorsports has been collecting valve spring kits from both AFR and TFS for years. We use these for machined castings for the various Mamo Motorsports products because they originate from PAC Racing in Michigan, and they are highly reliable. These are not the typical offshore knockoffs that we think are simply dangerous to use.

We are selling these as complete kits, so if you only need the springs themselves, or if you need something "a la carte" that you want us to build for you, please contact Mamo Motorsports directly for lower pricing on partial kits.

  • 450 lbs @ 1.200 (.600 lift)
