Why Upgrade Timing Cover Bolts?

OEM bolts:

• Corrode and weaken over time
• Strip easily after multiple removals
• Don’t always maintain consistent clamping force

ARP Fixes That:

• High-strength alloy construction for long-term durability
• Hex head design for easy installation with standard tools
• Reusable hardware (unlike factory bolts)
• Precision fitment for proper timing cover alignment

Translation: install it once, stop chasing leaks later.

To care for a reputation for “zero defects”, ensure that optimum quality regulate, and produce fasteners of exceptionally prime quality, ARP controls all aspects of the manufacturing process, performing all operations in-house where they may be able to be closely monitored.
