- ...and 5 additional applications
Enginetech replacement camshafts are manufactured to OEM specifications
to restore proper valve timing, lift, and duration to worn or damaged engines. Each
camshaft is ground to original profiles and hardened for durability. Always install a
new timing set and replace all lifters when replacing a camshaft - reusing worn lifters
on a new cam lobe will cause rapid wear and premature failure. Use the specified follower
type (flat or roller) as noted. Enginetech offers complementary components including
timing sets, lifters, and complete engine rebuild kits. Verify part fitment by year,
make, model, and engine displacement before ordering.
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.
