Introduction
The kep 13228srs08 is a standout component in the world of VW-based performance builds, Subaru-to-VW transaxle conversions, dune buggies, off-road rails, and kit-car projects. This 228 mm rigid clutch disc has earned a reputation for strength, durability, and smooth engagement, making it a favorite among builders who demand reliability under harsh conditions. Whether you’re upgrading a Baja Bug for off-road trails, converting a Beetle to Subaru power, or assembling a lightweight sand rail, the KEP 13228SRS08 often appears at the top of recommended clutch components.
The naming structure of this disc already reveals a lot: KEP refers to Kennedy Engineered Products, 13228 indicates a 228 mm (9-inch) diameter disc, and SRS08 identifies the rigid hub and full-circle friction style. These characteristics place it in a sweet spot—stronger and smoother than puck discs, but more performance-driven than comfort-oriented sprung discs.
In this article, you’ll learn everything you need to know about the KEP 13228SRS08, including specifications, benefits, ideal use cases, installation tips, comparisons to other disc types, maintenance insights, and real-world user experiences. This is the most comprehensive guide available for enthusiasts deciding whether this 228 mm rigid clutch disc is the right choice for their build.
What is KEP 13228SRS08 Exactly
The KEP 13228SRS08 is a 228 mm rigid hub full-circle clutch disc designed for engines that produce higher torque than what the original Volkswagen clutch system was intended to handle. It is commonly used in applications where a stronger, smoother, and more heat-resistant clutch disc is required.
Breakdown of the Part Number
- KEP – Stands for Kennedy Engineered Products, a major manufacturer of high-performance clutch components, VW engine adapter kits, pressure plates, flywheels, and more.
- 13228 – The number 228 refers to its diameter of 228 mm (or 9 inches).
- SRS08 – This designator identifies a rigid hub with a full-circle friction ring, meaning the disc has no springs or dampers, and the friction surface wraps around the entire circumference rather than being divided into pucks.
