Our lightest .937 lifter body
Successfully run through the 2016 NASCAR season, Jesel’s Integrated Keyway Roller Lifter is our lightest Keyway style lifter available. Currently available in a .937” diameter body with a .850” diameter roller, this lifter weighs in at a scant 96 grams – 6 grams lighter than our current TS Series Keyway.
By machining the guide key into the body, the aluminium keyway retention post is removed allowing for the use of larger diameter pushrods. Aluminium pistons feature an O-ring to prevent oil pressure bleed and a hardened steel pushrod seat available in either on-center or .150” offset location. Jesel’s Integrated Keyway lifters retain all the standard features of our TS series such as DLC coated Tool Steel bodies, oil pressurized needle bearings and they are a direct replacement to the TS series.
Jesel Keyway lifters require special engine block machine work to install the Jesel bronze keyway bushings. Jesel offers a Keyway Bushing Installation tool for sale or rent that ensures perfect keyway to bushing alignment.
