Heavy-Duty Forged Rocker Arm Set for Cummins ISX
Part Number ⚙️: 054777
Upgrade your ISX with a complete set of forged intake and exhaust rocker arms—built to outlast and outperform the cast originals. Whether you're rebuilding an engine or replacing worn rockers, this set delivers unmatched strength and durability under load.
