100mm - 150mm Slugs / Fork Extensions – Triumph Thruxton / Bonneville / Speedmaster
Material: 6061 T6 Billet Aluminium
Fitment: All Air Cooled Triumphs with 41mm legs
Take your Triumph to the next level—literally. These 100mm or 150mm fork extensions are designed to give your front end a taller, more aggressive stance while improving clearance for custom wheels or fenders. Machined from high-strength 6061 T6 aluminium, they offer an ideal combination of lightweight performance and durability.
Features:
- Precision CNC-machined from aircraft-grade 6061 T6 aluminium
- Adds 100mm (4 inches) or 150mm (6 inches) of fork height
- Easy bolt-on installation—no modification required
- Perfect for custom chopper or bobber build
Whether you’re chasing a more stretched-out front end or just need extra clearance, these fork extensions offer a clean and safe solution built to handle the road ahead.
Extending the forks will also distance the wheel out further from the bike - you may require a Extended Speedometer Drive Cable which can be found here.
