Description
When you're pushing 600, 700, or 800 horsepower through a classic Ford big block, standard single-disc clutches become a liability - they either slip under power or engage so aggressively they're miserable on the street. The McLeod RST twin disc clutch kit solves this problem by doubling your friction surface area without increasing pedal effort, giving you the holding power of a race clutch with the drivability of a stocker.
The RST uses twin organic-faced friction discs with sprung hubs that provide progressive, linear engagement - no on/off switch behavior that makes stop-and-go traffic a chore. The organic facings are specifically tuned for street performance, delivering smooth takeoffs and excellent release characteristics while handling up to 800 horsepower at the crank. McLeod's Blanchard-ground floater plate incorporates multiple retention straps to eliminate rattle and reduce drivetrain noise, keeping your high-powered street machine civilized.
A key advantage of the RST system is McLeod's patent-pending adapter ring design. This CNC-machined and anodized ring bolts directly to your existing large-diameter Ford flywheel - no need to purchase a dedicated flywheel for the twin-disc setup. The adapter ring fits flywheels with 164-tooth, 176-tooth, 180-tooth, and 184-tooth ring gears, accommodating Ford 351 Cleveland, FE-series (390/427/428), and 385-series (429/460) big blocks. The kit supports multiple pressure plate bolt patterns including 11" Long, 11-5/8" Equalizer, and 12-3/8" Equalizer configurations.
This RST kit is engineered for aggressive street driving and occasional strip use - not full competition. For racing applications, McLeod recommends their RXT or RXT 1200 series. The 10-spline x 1-1/16" input shaft configuration fits original Ford top-loader style transmissions commonly found in classic muscle car applications. Works with both mechanical linkage and hydraulic throwout bearing setups.
Kit Includes
- Diaphragm-style pressure plate assembly
- Two organic friction discs with sprung hubs
- Blanchard-ground floater plate with retention straps
- CNC-machined and anodized adapter ring
- Pilot alignment tool
- Installation instructions
Note: Pilot bearing and throwout bearing are not included. Flywheel resurfacing is required for proper installation and clutch longevity. For best results, flywheel surface should have a coarse texture from a stone grinder.
