Why Cam Bolts Matter (A Lot)

Factory cam bolts:

• Are often torque-to-yield
• Not designed for repeated installs
• Can loosen or stretch under performance use

ARP Fixes That:

• Pro Series alloy construction for maximum strength
• Higher clamp load to secure cam gear and timing components
• Reusable design (install/remove without gambling)
• Precision threads for accurate torque application

Translation: your timing stays locked in, even when you’re pushing the engine hard.

To care for a reputation for “zero defects”, ensure that optimum quality keep an eye on, and produce fasteners of exceptionally top of the range, ARP controls all aspects of the manufacturing process, performing all operations in-house where they are able to be closely monitored.

Vehicle Fitment (GM LS & Performance Applications)

The ARP 300-1001 kit is commonly used in:

GM LS Engines:

• LS1 / LS2 / LS3
• 4.8L / 5.3L / 6.0L / 6.2L platforms

• Camshaft upgrades
• High-performance or racing builds

This cam bolt kit is a great example of how ARP takes ordinary steps to produce the very finest products of their kind in the marketplace nowadays. ARP quality delivers increased pre-load clamping force and assures positive timing gear register, even as increased material strength (rated at 200,000 psi) overcomes valve train harmonics and stress.

Key Features

• Pro Series ARP alloy construction
• 12-point head design for precise torque
• High clamp load capability
• Reusable hardware
• Application-specific camshaft bolts

Performance Benefits

• Maintains accurate cam timing under high load
• Prevents bolt stretch or loosening
• Supports aggressive cam profiles and high RPM builds
• Improves long-term valvetrain reliability

No more wondering if your timing is about to shift mid-pull.

Added features include oversized bolt head flange for cam button retention and reduced socket head size to facilitate easy installation and removal. The kit includes the appropriate fasteners for your application.

Installation Notes

• Use ARP Ultra-Torque lubricant or thread locker as specified
• Torque to ARP recommended specs
• Install during:
  • Camshaft upgrades
  • Timing set installs
  • Engine rebuilds

Why ARP?

Because internal engine hardware is:

• Not visible
• Not exciting
• Absolutely critical

And ARP is what you use when failure isn’t an option.

Helps put an end to your camshaft timing worries
Rated at 200,000 PSI, which is considerably stronger than Grade 8 hardware
Features 7/16 inch socket size, 5/16-18 diameter/thread size, and .750 under head length
Reduced socket head size facilitates easy installation and removal
Oversized bolt head flange improves cam button retention

Final Verdict

The ARP 300-1001 Pro Series Cam Bolt Kit is a must-have upgrade for any LS or performance engine build involving cam work.

Small part. Huge consequences if ignored.
