RED-ZONE Solid Needle Roller Lifters

Red Zone Roller Lifters feature the new Marathon Roller Bearing the bearing that keeps on rolling longer! Marathon 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 Bearings withstand higher (up to 1/2 ton) spring loads, delivering over twice the number of runs between rebuilds!
