Eliminate the biggest weak link in your Ford English axle drivetrain with the Blackline Heavy Duty Group 1 halfshaft. Machined from high-strength 4340 steel, this uprated shaft is built to handle up to 300bhp when correctly set up, making it the ideal upgrade for fast-road, track, and stage-rally builds.
Unlike overly rigid shafts that transfer violent impacts straight into your gearing, the controlled ductility of these 4340 shafts helps absorb aggressive shock loads, protecting your differential and crownwheel and pinion from premature failure.
How the Group 1 Setup Works with the Bearing:
- Two-Piece Design: Unlike a stock factory halfshaft where the shaft and wheel hub/flange are a single forged piece, the Group 1 setup separates them into the shaft and a distinct end flange.
- No Separate Bearing Collar: On an OEM factory English halfshaft, a pressed-on metal collar is used to lock the bearing in place. The Group 1 design eliminates this collar entirely; instead, the separate bolt-on flange clamps down tightly against the inner race to lock the bearing securely onto the shaft.
- Retaining Hardware: It still seats inside the standard axle casing using the classic English axle wheel bearing dimensions and utilises a standard-style halfshaft retaining plate to secure it to the axle casing.
