EMPI Porsche 934 CV Joint — Joint Only, for 930 Turbo & 934 Axles (98-5097-B)

Turbo-era torque punishes a driveline in a way a stock engine never does, and the 934 constant velocity joint is the heavy-duty answer built to take it.

This is the EMPI 98-5097-B joint on its own, so you can rebuild a 930 Turbo or 934 axle with fresh boots and grease instead of buying the whole assembly.
