Mechanical Roller UltraMax Bushed Direct Lube Lifters; Chevy 265-400 Howards Cams 91142 - Howards Cams - 91142
UltraMax Bushed Direct Lube Chevrolet 265-400 Mechanical Roller Lifters We took the severe application ProMax lifters one step further to make the ultimate lifter for severe racing applications. We replaced the needle bearings in the roller tip with solid bushings. These lifters are made for ultra high spring pressures and the most aggressive cam lobes. They also feature “Full Time” high pressure oiling to the bearing axles. This continuous oiling in conjunction with the solid roller bushings offer the highest rpm and high spring pressure capability available. The UltraMax features lightened, steel alloy bodies with a special enhanced finish. Heat treated stainless steel link bars. Case hardened 8620 rollers. .300” taller body allows lifter to fit early, late model and after market blocks. Fully Rebuildable. Made in the USA!
