Why Timing Cover Bolts Matter

Factory bolts:

• Corrode over time
• Lose clamping consistency
• Can strip or weaken after multiple removals

ARP Fixes That Instantly:

• Stronger clamping force for proper gasket sealing
• Reusable hardware (no more one-and-done bolts)
• Precision fitment for LS timing cover alignment
• Clean 12-point design for easier installation

Translation: no leaks, no headaches, no redoing the job.
