Crower 73690-16 SBC Enduro Centerline Roller Rocker Arms

Crower designed these 73690-16 Enduro Centerline Roller Rocker Arms for Small Block Chevy 265-400 engines using .100 long valves.

When using a .100 long valve, the rocker arm tip must be backed up .050 to ensure centerline contact at half lift. Crower offsets the rocker stud hole in the trunnion, pulling the rocker tip back into correct alignment with the valve stem. Re-establishing correct geometry reduces valve guide wear while promoting more precise valve timing.

Made from 17-4PH stainless steel with 1025 heat treating, these proven rollerized rockers feature premium, oversized needle bearings, sure-lock rocker nuts as well as alloy steel tip rollers. The superior lightweight body design provides plenty of clearance for large diameter springs as well as drop on installation. Includes sure-locks.
