If you're doing a JZ swap in an S14, you'll need a driveline. We've got several options to chose from.
The fitment of our drivelines is based on our swap motor brackets and cross member and in some cases, transmission adapters. The fitment is based on an S14 NON-ABS chassis. This driveline will be to long for ABS differentials!
While many transmissions are "similar" in fitment, we build each driveline for it's specific application. For the JZ swap we currently support the W58, R154, Nissan VG 5 speed and Nissan VQ (CD009) 6 speed.
Xcessive makes all of their drivelines from 3" x .083 DOM steel. We've found steel to handle the most abuse and last the longest but we can also make aluminum shafts, just inquire for cost. All shafts are hydraulically pressed together in phase, rotationally welded then straightened before balancing. The universal joints are size 1310 and the slip yolk and rear flanges are sized to match, no stepped down conversion universal joints. All components are new, never sourced from old drivelines
