What is the purpose of the larger inner bearing race?

The larger inner bearing race is designed to reduce stress on the components. This helps to increase the overall lifespan of the axle, bearing, and roller within the tappet assembly.

Are these tappets sold individually or as a set?

This product is sold as a set of four tappets. It also includes the HL2T limited travel kit, making it a comprehensive package for your engine.

What does 'hand-fit and then pressure-tested' mean for these tappets?

It means that each individual lifter body and plunger assembly is carefully matched and assembled by hand. After assembly, they undergo pressure testing to confirm they meet performance and sealing standards before being shipped.

Product Details

Starting with a larger inner bearing race, these S&S Cycle hydraulic tappets are built to handle more stress and extend the life of your axle, bearing, and roller. They are designed to fit a wide range of Harley-Davidson Big Twin engines, including Evolution® models, and are also used in S&S® engines for Big Twin chassis from 1966-'84. This set includes four tappets, along with the HL2T limited travel kit, offering an updated design for improved performance.

Each lifter body and plunger assembly in this set is hand-fit and then pressure-tested to ensure proper function. The redesigned plunger assembly and revised metering device work together to provide consistent oil flow. This attention to detail in the build quality means you're getting a solid option for your engine rebuild or performance upgrade.

These tappets are a popular choice for those looking to get more out of their Big Twin engine. They are a direct fit for many Harley-Davidson models from the mid-80s through the late 90s, including popular bikes like the Electra Glide Classic and Fat Boy.
