Front axle geometry after a lift
A front lift that uses replacement radius arms and coil springs changes the axle position and the angle of the drive components. The radius arms control how the axle moves under braking and acceleration, so their mounting angle matters for both ride and driveline health. After installation, the front driveshaft angle, the brake lines and the steering components should be checked for stretch or binding.
Rear blocks and U-bolts set the rear height to match the front, which keeps the vehicle level and the wheel positions consistent. Uneven rear height can change how the front and rear share load, so measure both ends once everything is torqued. Re-check fasteners after the first few trips, especially on rough roads.
- Check driveshaft angles after installation
- Re-torque radius arm and U-bolt fasteners after the first trips
- Recheck brake lines and steering components for stretch
