Fitment Notes

• This is the Upper (transmission / pressure plate side) replacement ceramic disc for the Comp1 / Competition Clutch K-Series Twin Disc Clutch Kit (4-8037-C) only
• Spline: 1-1/32" x 24 - matches the K-Series hydraulic transmission input shaft; not interchangeable with B-Series discs (1-1/32" x 22 spline)
• Not compatible with the K-Series Super Single kit (4S-8037-C) - that application uses TM2-880K-C
• Not compatible with the K-Series Triple Disc kit (4T-8037-C) - that assembly uses a different upper disc
• Not compatible with B-Series twin disc kits (4-8026-C) - those use the TM2-880-A / TM2-880-B series
• Sold as a single disc; order quantity as needed for your rebuild

Features

• Direct replacement for the upper (transmission / pressure plate side) ceramic disc in the Comp1 K-Series twin disc assembly - enables targeted disc replacement without purchasing a complete new kit
• 1-1/32" x 24 spline is engineered specifically for the K-Series hydraulic transmission input shaft - direct drop-in replacement with no modification required
• Ceramic friction material provides superior heat resistance and high torque capacity consistent with the 4-8037-C kit's 500-1,200 hp rating
• Rigid hub design eliminates compliance under high torque load - engineered for all-motor, nitrous, boosted, and drag-race K-Series builds
• Disc position in the stack: uppermost disc, closest to the pressure plate and transmission input side of the twin disc assembly
• Individual disc replacement minimizes rebuild cost - service the worn disc without replacing the flywheel, pressure plate, or floater plate
• Manufactured by Comp1 / Competition Clutch in the USA

Product Description

The Comp1 Clutch TM2-880K-A is the upper (transmission / pressure plate side) replacement ceramic disc for the K-Series Twin Disc Clutch Kit (4-8037-C), covering 2002-2006 Acura RSX, 2004-2008 Acura TSX, 2003-2007 Honda Accord, 2002-2011 Honda Civic Si, 2002-2006 Honda CR-V, and 2003-2011 Honda Element applications equipped with the K-Series hydraulic transmission. The "A" designation in the 880K family identifies this as the upper disc - the disc closest to the pressure plate and transmission input shaft in the twin disc stack, engaging first under clamping load.

The 1-1/32" x 24 spline is specific to the K-Series hydraulic transmission and is not interchangeable with B-Series discs, which use a 1-1/32" x 22 spline - confirming the correct part is essential before ordering. The rigid hub ceramic construction is designed for the full 500-1,200 hp torque capacity range of the 4-8037-C assembly, making this disc suitable for all-motor, nitrous, turbocharged, and drag-race K-Series builds. Selling the disc individually allows teams to replace only the worn component during a scheduled rebuild, significantly reducing overall service cost compared to purchasing a full kit replacement.
