McLeod 6305504HD RXT 1200 Twin Disc Clutch Kit with Billet Aluminum Flywheel GM LS-X 6-Bolt 168T 1-1/8x10

The McLeod Racing 6305504HD RXT 1200 is a complete twin disc clutch and billet aluminum flywheel kit engineered for GM LS-X engines with a 6-bolt crankshaft flange, 168-tooth ring gear, and 1-1/8" x 10-spline input shaft. Rated to handle up to 1,200 horsepower, this heavy-duty street/strip system delivers a higher clamp load than the standard RXT twin disc, making it the ideal choice for high-output builds that still demand daily driveability.

Key Features:

• 1,200 HP Capacity — Heavy-duty higher clamp load design handles extreme power while remaining street-friendly
• Twin Ceramic Disc Design — Ceramic-lined clutch discs deliver smooth engagement with moderate pedal effort, ideal for street and strip use
• Billet Aluminum Flywheel Included — Lightweight billet aluminum flywheel reduces rotating mass for improved throttle response and quicker revs, optimized for track applications
• 168-Tooth Ring Gear — Compatible with GM LS-X 6-bolt crankshaft engines (1997–2013)
• 1-1/8" x 10-Spline Input Shaft — Matches a wide range of manual transmission applications
• 0-Balance Configuration — Factory-correct neutral balance for LS-X engine applications
• Complete Plug-and-Play Kit — Clutch and flywheel sold together under a single part number; no need to source components separately

Kit Includes: Pressure plate, two ceramic friction discs, billet aluminum flywheel, floater plate, adapter ring, and pilot tool.

Flywheel Note: This kit includes a billet aluminum flywheel, which is the preferred choice for track and high-RPM applications. McLeod also offers billet steel flywheel variants for drivers who prioritize smooth street-driving characteristics and ease of low-speed operation.

Fitment Note: Requires a flat-style flywheel mating surface with a crank relief of 6.250" or smaller. This kit will not function correctly with recessed or stepped flywheels, or with crank reliefs exceeding 6.250" in diameter. Some driveline feedback tones between 1,200–1,900 RPM are normal with twin disc clutch applications.

McLeod Racing has been a leader in performance clutch and driveline technology since 1971, offering products that range from street performance replacements to race-ready systems capable of handling extreme power levels.
