Enginetech push rods are precision-ground stock replacement components
engineered to restore correct valve train geometry in your engine rebuild. Each
push rod is manufactured to exact OEM length and diameter specifications to
maintain proper rocker arm geometry and lifter preload. Accurate push rod length
is critical to engine longevity - undersized or oversized rods alter valve timing
and can cause premature wear on lifters, rocker arms, and valve guides. Always
verify push rod length, diameter, and lifter type compatibility before ordering.
Enginetech offers a full line of valve train components including valves, valve
springs, keepers, retainers, and rocker arm kits to complete your rebuild.
WARNING: This product can expose you to chemicals
including lead, which is known to the State of California to cause cancer,
birth defects, or other reproductive harm.
