Th400 Rapid Release Yoke

Mark Williams Extreme Duty transmission slip yokes are machined from high strength 4340 steel and thru hardened in house for ultimate strength. All machining is done in relationship to the spline pitch diameter to ensure each yoke is symmetrical for balance and smooth operation. Rapid release yokes allow the driveshaft to be disconnected at the transmission rather than at the pinion. The cap design prevents over-tightening and possible damage to the u-joint cups. Care must be taken not to mix u-joint caps and maintain indexing after shaft is balanced. MW-built driveshafts with these yokes have identifying index marks. Racing Use Only, Not Legal for Road Use.
