Brand New Group A 組 1 Piece Drive shaft

Material: Steel

Weight: 13lbs

Application: Corolla GTS (84-87)

Advantage: Quicker throttle response (like light weight flywheel)

Steel 1-piece replacement shaft for the AE86 platform. It used all new yoke and diff flange. Chevy 3/4ton user serviceable u-joints This shaft is about 5lb less than the factory 2-piece.  Faster throttle response due to the fact the carrier bearing is not moving up and down during acceleration. This will work with any engine using the stock T50 transmission -
