Connecting Rod Installation Instruction
RACE I-BEAM AND H-BEAM RODS
1. Clean rods completely, clean rod bolt area and threads with a suitable cleaner and dry compressed air to remove any foreign materials PRIOR TO
DISASSEMBLY! Disassemble rods by hand; never use an air ratchet or impact on rods. Clean rods completely after disassembly, clean rod bolt area
and threads with a suitable cleaner and dry compressed air to remove any foreign materials.
2. Lubricate threads and under head clamping face with a Moly bolt lube to reduce frictional torque. Never use any other alternative lube. Tighten
fastener with Torque according to the chart below. Never operate rods using torque less or greater than specified.
3. Never interchange rods between sets. Every rod is carefully sorted in sets by weight. Always install with the 45deg angle/champher facing the
crank radius where applicable.
4. To ensure proper installation, the following clearance is offered as a general guideline, it may vary by application.
5. All ARP 8740 Cap Screws are available for upgrade to ARP 2000.
6. Rod Bearing 0.002-0.003”, Piston Pin 0.0009-0.0015:, Side 0.015-0.025”.
