Black diamond performance clutches

  Black Diamond Performance have developed three stages of Performance Clutch Kits – Fast Road, Fast Road/Competition and a full Race Paddle Clutch capable of handling and transmitting the torque generated, as well as providing a range of other benefits.

 Utilising our experience in brake disc technology, all of our clutches have grooves machined into the pressure plate surface. These grooves help to dissipate the heat generated as well as remove the dust and gases created.

Updated in March 2023, our range is bigger than ever before. Over 10,000 applications available in the three stages, Stage 1 PWR, Stage 2 KVR and Stage 3 PDL meaning there are over 30,000 part nos.

Stage 1 - Fast Road
Our Stage 1 clutch kit is recommended for vehicles with up to a 20% increase in torque above standard. The clutch disc has a spiral woven glass fibre friction material with a heavy copper core. The glass fibre is a fairly soft material which allows for a smooth engagement of the clutch and consistent performance from low to high temperatures. The added copper in this friction material allows the clutch to perform well at even higher temperatures, as well as improving burst strength (approximately 9000 RPM) and helping to dissipate heat through the material. The strong springs used in Black Diamond’s Stage 1 clutch kit create greater clamping pressure on the clutch disc, providing a more instant response and reducing the chance of unwanted slippage. As the organic compound used in the Stage 1 clutch disc is relatively soft, it also benefits from a minimal breaking in period.

Stage 2 - Fast Road / Competition
Black Diamond’s Stage 2 clutch kit uses an aramid fibre friction material similar to Kevlar and is recommended for vehicles with a torque increase of up to 30%. These clutch kits provide an even stronger clamping pressure than the Stage 1, as well as boasting an even higher burst strength. This is aided by the extreme hardness of the aramid fibre material, which is nevertheless very lightweight. This friction material requires a breaking in period of about 600 miles of gentle use, this is to ensure it reaches it’s full friction qualities. The Stage 2 clutch kit is capable of withstanding the high temperatures associated with competition driving and so is ideal for the track. With the rigidity of these drive plates it's important that all flywheels are checked for wear as any imperfections or dishing of the flywheel will result in loss of contact with the friction material.

Stage 3 - Full Race
Our Stage 3 clutch kit is recommended for increases in torque of between 30 and 60%. We use a cerametallic friction material, allowing it to be able to cope with extremely high heat and torque. These paddle clutches are an excellent option for track use, heavily modified engines and chipped or mapped diesels where the torque increases exponentially. Black Diamond’s Stage 3 clutch kit, with its very high clamp load and stainless steel backing plates ensures that maximum torque is transmitted from the engine to the wheels on the ground with minimum risk of overheating or slipping. Our stage 3 paddle clutch retains the driveability required in normal road use, although some changes to driving style are required (more revs to pull away). We can make your paddle clutch with 4, 5 or 6 paddles depending on the diameter of the drive plate.

Making the right choice of clutch for your vehicle and driving style is important. However, you can rest assured that whatever Black Diamond clutch kit you choose, it will be made to order from the highest quality materials. To ensure the quality and precision of manufacture expected of a Black Diamond clutch kit, all our clutches are individually tested for lift and load. Our clutch kits are also designed to be direct replacements for a vehicle’s standard clutch, meaning no alteration to the flywheel or any other standard part is necessary.
