The New Red ZoneTM Roller Lifters

RED ZONETM Roller Lifters feature the new MarathonTM Roller Bearing -- the bearing that keeps on rolling longer! MarathonTM 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, MarathonTM bearings withstand higher (up to 1/2 ton) spring loads, delivering over twice the number of runs between rebuilds!

Test Proven RED ZONETM Safe! MarathonTM 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!
