Roads Original V-Max Super Lube Roller Lifters give you all remarkable features of Rhoads Original Roller lifters with the addition of a patented groove down the entire length of the lifter body, constantly injecting oil on vital wear surfaces where lifter and cam face meet. Rhoads Super Lube lifters eliminate the need for costly grooving modifications to the lifter bores in the engine block. The Super Lube feature greatly improves longevity along with reduced friction. For maximum increases in low-end torque, engine vacuum and improved idle quality, Rhoads V-Max Super Lube Variable Duration Roller Lifters are the answer. These unique lifters are designed to significantly increase low-end torque and engine vacuum. 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. Rhoads V-Max roller lifters 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 in. lift depending on the adjustment. As the rpm increases, so does your valve lift and duration. Complete lift and duration restoration takes place at approximately 4000 rpm. V-Max series roller lifters are also 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.
