What makes these tappets 'precision'?

The 'precision' refers to the hand assembly process where each tappet is put together to very close tolerances. This meticulous build ensures low leak down rates, which is key for fast pump-up and quiet operation.

Will these tappets make my engine run quieter?

Yes, these tappets are designed for quiet operation. The close tolerances and rapid pump-up help reduce valve train noise, contributing to a smoother and quieter running engine.

Are any special tools or parts needed for installation?

Installation of tappets typically requires specific tools for accessing and replacing internal engine components. It is recommended to refer to the manufacturer's installation instructions or consult a qualified mechanic for the proper procedure and any necessary accompanying parts.

Product Details

S&S Cycle is well-known for building performance engine components, and these Precision Tappets are a great example of their work. They're designed as a high-performance replacement for the stock lifters in a wide range of Harley-Davidson motorcycles, including M8, Twin Cam, and late Sportster models. If you're looking to reduce valve train noise and improve how your engine responds, especially at higher RPMs, these tappets are worth considering.

What sets these tappets apart is the meticulous hand assembly to very close tolerances. This precision means they have low leak down rates, which helps with rapid pump-up and contributes to quieter operation from the moment you start the engine until you shut it down. This attention to detail ensures consistent performance and a more refined feel from your engine.

These tappets are made in the USA and are a solid option for riders who want improved performance and a quieter valve train. They fit a broad range of Harley-Davidson models, such as the Road King, Street Glide, and Fat Boy, among many others.
