Good To Know

Q: Does this rocker arm fit both intake and exhaust positions? A: Fitment depends on the cylinder head and stud arrangement, so confirm position requirements against your build before ordering. Q: Is a matching set required? A: Rocker arms are typically replaced as a matched set for even wear, so plan accordingly for your valve train.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
