Why It Matters
A weak or stretched cam bolt can lead to:
- Timing drift or failure
- Cam gear slippage
- Catastrophic engine damage
The ARP 134-1003 ensures maximum clamping force and reliability, keeping your timing components locked in place—even under aggressive driving or high RPM.
Installation Notes
- Always follow ARP torque specs
- Use proper assembly lubricant (ARP Ultra-Torque recommended)
- Clean threads before installation
- Don’t over-torque—this isn’t a lug nut
Install an ARP cam bolt kit and end your camshaft timing worries! ARP quality delivers increased pre-load clamping force and assures certain timing gear register. Includes suitable fasteners on your application. Increased subject matter strength overcomes valve train harmonics and stress. Added features come with outsized bolt head flange for cam button retention and reduced socket head size to facilitate simple installation and removal. To be had in both Prime Performance and Professional Series kits.
Vehicle Fitment
- Chevrolet – All Models (application-specific compatibility required)
Commonly used in:
- Small Block Chevy (SBC) builds
- LS-based engine setups
- Performance and racing applications
Always confirm compatibility with your specific engine and cam setup—because “all models” never actually means all models.
Final Verdict
The ARP 134-1003 Cam Sprocket Bolt Kit is a must-have upgrade for any serious Chevy engine build. It’s one of those small parts that quietly prevents massive failure.
Not exciting—but neither is rebuilding your engine because a bolt gave up.
