The New Red Zone^TM Roller Lifters

RED ZONE^TM Roller Lifters feature the new Marathon^TM Roller Bearing -- the bearing that keeps on rolling longer! Marathon^TM bearings utilize a larger diameter pin and a shock absorbing, thicker outer race for higher fracture toughness! The resulting increased cross sectional area helps prevent premature bearing failures even under the sustained RPM red line abuse of professional endurance racing. In drag racing, Marathon^TM bearings withstand higher (up to 1/2 ton) spring loads, delivering over twice the number of runs between rebuilds!

Test Proven RED ZONE^TM Safe! Marathon^TM bearings routinely log back to back 1,000 racing mile endurance runs via the most rigorous, real-world test standard ever created, Spintron Test II. It's a no holds barred run as high as 9,000 RPM, where face ending competitive abuse is continuously revisisted!
