Product Details

The Stage 8 8911B locking header bolt kit (also called exhaust manifold bolts) helps guard against horsepower loss and gasket failure caused by loose header bolts or nuts. Each locking bolt uses a three-piece design: a bolt made of 4130 alloy steel, a locking retainer and a spring clip.

Key Features:

  • Thread size 3/8-16, 1-1/4" length
  • 12-point head
  • Bolt made of 4130 alloy steel
  • Three-piece locking design: bolt, locking retainer and spring clip
  • Helps keep header bolts from loosening

Stage 8 locking header bolt kits are application specific, and are offered with either a hex head with a 3/16" recessed allen drive or a 12-point head, in USA or metric sizes. Kits include the hardware needed for the application.
