At JSI Auto Solutions in Los Angeles, near Inglewood, our expert technicians rebuild and service rocker arm assemblies — including the rocker arms, shafts or studs, pushrods, and adjusting screws — ensuring precise valve movement and optimal engine performance.

• Rocker Arm – the main lever that moves to open and close the valves.

• Rocker Shaft or Stud – supports the rocker arm and allows it to pivot.

• Pushrod (in pushrod engines) – transfers motion from the camshaft lifter to the rocker arm.

• Adjusting Nut or Screw – allows for precise valve clearance adjustment.
