For maximum increases in low-end torque, engine vacuum and improved idle quality, our newly developed and newly patented Rhoads V-Max OE Roller Variable Duration Lifters are the answer. They increase low-end torque and engine vacuum up to 50% more than Orginal Rhoads Lifters...and they rev higher too. This makes them the best choice for hot street, performance marine and all racing applications. Typical vacuum increases range between 3 to 5 inches at idle when used with bigger cams. They are fully adjustable and require an adjustable valve train. Adjustment is similar to solid lifters. Simply use a feeler gauge to adjust the exact amount of lift reduction you want, anywhere from .010" to .030", and that is exactly what you get at idle. Duration is reduced between 5 and 20 degrees at .050" lift depending on the adjustment. As the rpm increases, so does the lift and duration. Full restoration takes place at approximately 4000 rpm. For engines equipped with adjustable valve trains, Rhoads V-Max OE Roller Lifters are definately the best choice. They are particularly suited for racing applications with vacuum rules. You can run more cam than your competition while still meeting vacuum requirements, giving you the performance advantage. They are also useful in allowing larger cams to be used in computer controlled engines without disrupting proper computer functions.
"As a former Air Force Pilot, I am concerned about performance. I have installed exotic camshafts, intake manifolds, carburetors, ignition systems and even water injection, but it was not until I installed your lifters that I could tell a real improvement in performance. Just thought I would let you know."----Paul Russell, LT. Col. USAF - Retired
