S&S Cycle Roller Rocker Arm Complete Rebuild Kits

S&S Cycle roller rocker arm complete rebuild kits offer several benefits for Harley-Davidson® motorcycles, including significantly reduced friction on the valve stem, improved valvetrain longevity, increased horsepower potential, especially at higher rpm's, and smoother engine operation. These kits also offer better compatibility with high-lift cams due to the reduced wear and side load on the valve stem from the roller design; essentially providing better overall performance and durability compared to stock rocker arms. Order the rebuild kit designed for your HD® model.

Features and benefits:

* Complete kit includes roller tips, roller pins, roller pin retaining clips, and rocker arm bushings to rebuild a set of four S&S forged roller rocker arms
* Designed using Finite Element Analysis (FEA) and forged from 8620 steel for strength
* The roller design minimizes friction on the valve stem, leading to less wear and tear on both the valve stem and rocker arm, extending the lifespan of the valvetrain components
* The roller bearings in the rocker arms distribute the load more evenly, leading to better wear resistance compared to traditional sliding contact on stock rockers
* Roller rockers are designed to handle the increased valve lift associated with performance cams without excessive wear or stress on the valvetrain
* Rocker geometry is better suited to high-lift camshafts
* Bushings are longer than stock, increasing the time between rebuilds
* The smooth rolling action of the roller bearings can contribute to a quieter engine operation
* Compatible with stock or S&S CNC-machined heads
* Many high-quality roller rocker arm kits are designed to be serviceable and rebuildable, allowing long-term use with proper maintenance

Notes: When installing roller rockers, it's important to choose a camshaft that is compatible with the increased valve lift capability. Also, precise installation is crucial to ensure optimal performance and avoid potential issues.
