This is our stealth lock-up clutch that fits under the stock side cover with only slight modifications. The lock-up is machined from 6061 billet aluminum, anodized black and utilizes ball bearings to apply pressure to the clutch pack. The billet pressure plate that houses the ball bearings takes the place of the stock cast pressure plate giving it a more ridgid durability.
Our lock-up uses ball bearings to apply pressure to the clutch pack and is fully adjustable from the trail rider to the full drag racer. The amount of pressure that is applied to the clutch varies depending on the amount of ball bearings used in conjunction with the clutch spring stiffness. We have used our lock up clutch on 50H.P. quads up to 145H.P. drag engines.
The purpose of a lock up clutch is to limit the amount of clutch slippage and apply the H.P. to the ground. Since there is a limited amount of clutch slippage the life span of the clutch pack is greatly extended.
