Reused cam bolts stretch, back out, and take your timing — and your engine — with them. This high-strength cam retainer bolt kit delivers the clamping force to keep your timing gear registered and torqued through valvetrain harmonics that fatigue factory hardware.

  • High-strength alloy steel resists stretching and vibration loosening
  • Increased pre-load clamping force for positive timing gear register
  • Fits Chevrolet Gen III LS small block (4.8L, 5.3L, 5.7L, 6.0L)
