Description

Cummins 1.4 Dia. Nitrotech Tool Steel Flat Tappet Lifter.

Made with most advanced technology, and materials, these are the most preferred lifter used by top engine builders and racers. These tool steel lifters are built to take high rpm, and higher than stock spring pressures found in today’s vehicles. We have many miles of testing, track time, and dyno time on these lifters. They provide a superior durability and wear over the stock lifters, and DLC Coated Lifters. They are also much stronger, and resistant to cracking. We have used these in street, modified street, drag racing, and pulling vehicles. These lifters work very well with steel camshaft cores and cast camshaft cores. They will take pressures up to 600 lb. open spring pressure, in comparison to stock lifters that are only good to the 350 lb open spring pressure or DLC that start to fail at 500 lb. open.

Features include:

•  Tool Steel Body increases strength and virtually eliminates mushrooming of base material.
•  Crowned face promotes lifter rotation and reduces lifter wear.
•  Micro polished face reduces wear of the lifter face.
•  Large Diameter Foot for high velocity, and acceleration lobe profiles.
• Proprietary heat-treating process that creates a hardened and lumbricid layer that significantly reduces wear.  Superior wear characteristics to coated lifter tappets.
