Key features
- Yoke for TeraFlex High-Angle Rzeppa CV drive shaft conversion
- Dust shield included
- Made for models with a 3 to 6 inch lift
- Lists 2-door and 4-door 2007–2018 Wrangler JK models
Driveline angles and lift
A high-angle CV conversion changes how the driveline sits, so the yoke and shaft must work at steeper angles than a standard setup. Lift height changes those angles again, and the combined effect determines whether the joints stay within their operating range and whether the dust shield clears moving parts under articulation.
Before final assembly, check the shaft length, the pinion and transfer case angles, and clearance to the crossmember and frame at full droop. Inspect the dust shield for contact during articulation, and recheck the bolts after the first drives on the trail. Shops that handle these conversions often verify angles with measurements, which is a sensible step for any driver who changes lift or tire size later.
- Measure driveline angles after the lift is installed
- Check dust shield clearance at full articulation
- Recheck fasteners after the first trail runs
