Product Description
Clutch Kit POWERspec - 5 SPeed Gearboxes - STC8361HDPS5 - LOF
POWERspec
The POWER spec is the next stage up, ideal if you use your Land Rover as a work horse. If you tow regularly or carry any extra weight like expedition trucks do then this is the spec for you. It’ll handle highly tuned road monsters or hard worked off-roaders all day long. If you want reliability and driveability from your mapped motor the POWER spec will keep you moving forward!
The organic friction material as fitted to both the ROADspec and POWERspec clutch kits is the highest possible grade of premium organic clutch material available in Europe.
The Friction is of a woven composite construction rather than lower grade Laminate/Moulded type frictions, giving improved stiffness and wearing capabilities. The woven technique is ideal for preventing Delimitation of the friction face which can quickly lead to serious clutch failure.
The friction material has been engineered to contain high levels of copper and brass, which gives it the ultimate protection against heat damage and clutch fade. With Burst strengths of over 11,000 RPM, the HDTF is superior to cheaper faces which can begin to break up at as little as 5000 RPM.
One of the fundamental reasons clutches fail on high torque applications is due to the clutch plate centre hubs. On most low quality or mass produced clutches the manufacturers run a ‘coined’ centre hub. This allows them to manufacture various different hubs by pressing the splined section in to the centre hub.
LOF have gone out of our way to resolve this issue by sourcing and in some cases having our own centre hubs manufactured from a single piece. This means they cannot separate or spin out. We realise that for a reliable and strong clutch a solid centre hub is a basic requirement, especially with Mapped and Tuned engines that are producing more torque.
The way that OEM manufacturers specify clutches for Land Rover is to work on a maximum torque rating of the engines stated maximum power figures and then add as little as 10% as a load buffer.
LOF clutches know that’s not enough! Therefore through extensive research and development they have designed clutch plates that have maximum Torque of over 40% greater than the standard book value.
The Clutch Cover is the simplest component in the clutch kit, LOF clutches spent a lot of time sourcing the right parts to make a solid Cover. The two main concerns are diaphragm spring load and the shape quality and material used in the cover. The cover needs to cope with a lot of heat. It needs to be substantial enough to absorb then dissipate the heat. It also needs to be thick enough and have enough material so it doesn’t warp due to the enormous heat involved.
The diaphragm spring needs to have a high enough load rating so that it gives enough clamping force for the job but not so high that it causes strain and stress on the other components in the clutch system. LOF inspected and tested various clutch cover components to find the characteristic they needed to build their clutches to the highest specification and quality.
