The deeper profile increases oil capacity by up to 100cc helps reduce oil temperature in long races especially in extreme muddy/sandy conditions where clutch abuse is most common. Our Clutch Covers are CNC machined from a solid billet of 6061-T6 aluminium which allows thin light weight sections to be machined whilst still increasing strength and durability over standard covers. This helps to resist damage from stones/rocks/footrests and brake pedals which can hole a standard cover almost guaranteeing a DNF. Theu also feature an extra tough Black Anodized  surface treatment which drastically increases the wear resistance from boots and grit to give a lasting stylish look.
