Description
Converting an LS engine to run with a classic GM 4-speed transmission requires a clutch setup that bridges the gap between modern engine bolt patterns and vintage transmission spline counts. This MDL Superior clutch kit solves that fitment challenge head-on, pairing an LS-pattern diaphragm pressure plate with a 10-spline clutch disc sized for early Muncie and Saginaw 4-speeds built before the 1971 switch to 26-spline input shafts.
The steel-backed organic friction material delivers reliable clamping force while offering superior burst strength compared to standard organic facings. That steel reinforcement also improves heat dissipation, extending clutch life and allowing quicker recovery during spirited driving. Heavy-duty torsional dampening springs on the hub absorb engagement shock for a smooth pedal feel that suits street cruising and daily driving.
The low lever height design is critical for hydraulic release setups, ensuring proper throwout bearing geometry and consistent travel throughout the release arc. If you're running an internal or external hydraulic slave cylinder, this is the clutch geometry you need for clean, predictable engagement every time.
All MDL Superior clutch discs are hand-built in-house so every kit meets exacting tolerances before it ships. Each assembly is double-checked for accuracy, so what arrives is a ready-to-install, premium piece backed by a 1-year free-from-defect warranty. Made in the USA.
