Over 100,000 satisfied customers, including big
name engine builders like Gale Banks, will tell
you...With Rhoads lifters you can run more cam and
still have great low-end torque, engine vacuum and
idle quality. The secret? Variable Valve Timing!
Rhoads' exclusive patented design reduces lift and
duration on the low-end and restores it on the top.
This lets you run more camshaft while retaining great
low-end streetability, fuel efficiency and better
emissions. And they are anti-pump-up for maximum
high-end revs. This makes Rhoads lifters ideal for
marine, strip or oval track
