Limited Slip DifferentialThe “EVOLUTION” limited slip has won yet another national championship!You too can know have the same limited slip that powered the Joe Huffaker Midget to last year’s national championship in F-Production. The EVOLUTION limited slip is a modern version of the Salisbury clutch type. It has improved clutch material and a unique design of smooth transitions between loaded and unloaded. Extremely easy and predictable to drive! This design will NOT allow the wheels to spin even if one of them loses contact with the ground. All our limited slips are pre-set for full race applications but can be changed easily for other applications. Modern engineering and design allows variations in static pre-load, percentage torque transfer and accelleration/decelleration action to be made. This facilitates tuning the diff to suit individual requirements and applications – be it road, rally or race! Static settings are easily changed by replacing one diff plate with a thicker one; a selective plate pack is available separately. Static pre-load is checked by holding the unit in a vise and checking slip-point with a torque wrench on one of the crown wheel retaining bolts. Percentage torque bias is increased by interleaving the plate configuration, but is also dependent on ramp angle; shallower ramp angles give higher percentage torque bias. The design of the cross pins and ramps in which they operate allow torque bias changes to be made. The closer to 90 degrees the ramp angle, the less action it has – so a 90 degree ramp effectively unlocks the diff making it behave like a standard diff. Conversely, the shallower the angle, the greater the locking action. There are three basic types available; “90/50” for gentle road use, “50/40” for rally and autocross, and “90/35” for full race.
