1 product

This category features JIMS billet aluminium rocker box covers, specifically designed for Harley-Davidson Twin Cam engines. These rocker covers provide an aesthetic and functional solution for the cylinder head tops, replacing the original cast components.

About this category

The billet aluminium construction ensures greater durability and a premium finish, available in matte black, gloss black, or chrome. Compatible with Twin Cam ‘A’ and ‘B’ engine configurations, widely used in Dyna, Softail, and Touring motorcycle families during the 1990s and 2000s. These covers enhance the engine’s appearance while protecting the internal valvetrain components. Ideal for restoration or custom projects, they allow direct installation without complex modifications to the engine block.
