Clutch Kits for Honda Civic MA

A clutch kit supplies the parts that work and wear together as one assembly, so they can be changed in a single job. Twin-disc and triple-disc clutches are listed here for street and race use, in grades of rising clamp load, with sintered iron friction material on some race kits.

Torque capacity rises with every pair of friction faces. A single-disc clutch has two faces, a twin-disc clutch four and a triple-disc clutch six, with floater plates between the discs. A multi-disc clutch can therefore carry more torque at a given clamp load and diameter, or the same torque from a smaller assembly.

A smaller assembly has less rotating inertia, so the revs rise and fall more quickly. Pedal effort can stay moderate, because the extra faces do the work that a much stiffer diaphragm spring would otherwise have to do. The costs are a sharper take-up, some rattle from the floater plates at idle, and parts that wear as a matched set.

Read the kit titles for:

• Disc count: twin-disc kits for strong road and track engines, and triple-disc kits, listed as race kits, for higher torque still.
• Street or race: street kits favour smooth engagement and quieter running in traffic, while race kits accept a harsher take-up and more noise in return for heat tolerance.
• Grade: most titles carry a grade code, and the digit after the opening T of the part number rises with the clamp load. Choose for your torque with a margin rather than the highest grade, as pedal effort rises with clamp load.
• Friction material: sintered iron, named on some race kits, copes with very high temperatures but engages abruptly and wears the plates it runs against.

A multi-disc clutch must go together in the right order, with each disc and plate the right way round. Follow the kit’s stacking instructions and keep its parts together as supplied. Torque the flywheel and cover bolts in stages to the stated figures, and check that the release system has enough travel to free every disc.

Bed the kit in gently before heavy use, and renew worn engine mounts, which let the engine rock and make take-up jerky. A stronger clutch passes bigger shock loads into the gearbox, driveshafts and differential, so make sure they can take the torque as well.
