Uses 1350 series U joint. Fits Powerglide and Turbo 350 transmissions. "D"=5-13/16". 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. Manufactured from high strength 4340 steel. 100% machining creates a perfect balanced part. weight 2.70# Installation - Service instructions can be found on Service Bulletin #0085.

*Note* Our previous design rapid release yokes had threaded holes in the ears for cap attachment, and were sold with standard caps. New style rapid release yokes have a through hole in the ears for cap attachment using the 2nd Generation alloy steel cap kit for added strength.
