ARP 155-1001 Camshaft Bolt Kit for Ford Big Block & Small Block

ARP's 155-1001 camshaft bolt kit is engineered to eliminate timing gear slippage and camshaft walk issues common in select Ford V8 applications. Manufactured entirely in-house under strict quality control, these premium fasteners deliver exceptional clamping force and reliability far exceeding OEM hardware. Rated at 170,000 PSI tensile strength, these bolts overcome valve train harmonics and stress that can cause timing problems in high-performance and racing engines.

Key Features:

• Oversized bolt head flange provides positive cam button retention and prevents camshaft movement
• Reduced socket head size (5/8 inch) facilitates easy installation and removal in tight engine compartments
• 3/8-16 thread size with 1.580 inch under-head length for proper engagement
• 170,000 PSI tensile strength—significantly stronger than Grade 8 hardware
• Ensures positive timing gear registration and eliminates camshaft walk
• Precision manufacturing guarantees consistent torque values and optimal preload

Application: Compatible with select Ford big block and small block engines including 1968-present 302, 351W, and 429-460 applications. Includes all necessary fasteners for proper camshaft retention.
