McLeod 6330103C Original Street Twin Clutch Kit Aluminum Flywheel Ford SBF 289/302/351 1-1/16x10 Spline 157T Cable

The McLeod 6330103C Original Street Twin is a complete twin-disc clutch and billet aluminum flywheel kit engineered for high-horsepower Ford small block applications. Rated up to 1,200 horsepower, this system delivers serious performance capability while remaining fully street-drivable — no compromises required.

The Original Street Twin Legacy:

McLeod pioneered the street twin-disc clutch concept in 1974, developing a solution for enthusiasts running power adders like nitrous oxide, superchargers, and turbochargers who needed a clutch that could survive the power without sacrificing daily drivability. The 6330103C continues that tradition with a Ford small block-specific fitment covering 1963–1995 289, 302, and 351 engines.

Kit Features & Specifications:

• Flywheel: Billet aluminum construction — lightweight for reduced rotating mass and quicker throttle response
• Flywheel Balance: Zero (0) balance — pre-balanced for Ford SBF applications
• Flywheel Tooth Count: 157-tooth ring gear — compatible with factory Ford SBF starter
• Input Shaft: 1-1/16" diameter x 10-spline — matches common Ford manual transmission input shafts
• Clutch Pattern: 10.5" Borg & Beck
• Linkage Type: Cable linkage compatible
• Disc Facing: Organic friction material for smooth, progressive engagement and soft pedal feel
• Included Counterweights: 28 oz. and 50 oz. counterweights included for proper balance across SBF variants
• Includes: Pressure plate, two organic friction discs, floater plate, billet aluminum flywheel, adapter ring, and alignment tool

Performance Capability:

Whether your Ford small block is fed by a supercharger, turbocharger, nitrous system, or simply cubic inches, the Original Street Twin is built to handle it. The twin-disc design doubles the friction surface area compared to a single-disc setup, dramatically increasing torque capacity without requiring an aggressive or harsh-engagement disc material. The organic disc facing keeps pedal effort manageable for everyday driving.

McLeod clutch kits are pre-balanced to fit specific applications and include the correct alignment tool for a straightforward installation. This kit is the aluminum flywheel variant — ideal for builds where reducing rotating weight is a priority for improved acceleration and rev response.
