2883252 Rocker Lever

2883252 rocker lever is a valvetrain replacement component applicable to Cummins ISX12, ISX11.9, QSZ13 and Z13 engines. Using high-strength forged alloy, it undergoes surface hardening treatment to enhance impact resistance and wear durability. It works to open and close engine valves accurately following cam profile, securing proper air intake and exhaust discharge. Precision machining ensures smooth rotation and reduces friction loss inside valvetrain. OE-standard dimension enables simple bolt-on replacement without extra calibration. It is a reliable choice during engine overhaul to restore original power performance of Cummins heavy-duty engines.
