S&S Cycle 84-99 BT Billet Tappet Guide Set

If you're working on a 1984-1999 Harley-Davidson Big Twin engine, whether it's stock or modified, these billet tappet guides from S&S Cycle are a solid choice. They were originally developed for S&S engines, so you know they're built to their exacting standards. Tappet guides are crucial for keeping your pushrods aligned and ensuring smooth operation of your valvetrain. When they wear out or get damaged, it can lead to all sorts of performance issues, from noise to reduced power.

What sets these apart is the billet construction. This means they're machined from a solid block of material, which gives them superior dimensional precision compared to cast parts. This precision is key for consistent pushrod alignment, especially in higher-performance or modified engines where tolerances are tighter. The chrome finish not only looks good but also helps with durability and smooth operation. Having well-aligned pushrods means your valves open and close at the right time, contributing to better engine breathing and overall performance.

This set is designed to fit a wide range of Harley-Davidson models from 1984 through 1999, including popular bikes like the Road King, Heritage Softail, and Dyna Super Glide. Because they are a direct replacement for the stock tappet guides, installation should be straightforward for anyone familiar with engine work. Make sure you have the proper tools and refer to your service manual for specific installation procedures to ensure everything is set up correctly.
