Kelford uses modern CNC machines for small batches, ensuring high quality and precise tolerances. Our gears are crafted from premium 6061 T6 aluminum, with beveled tooth edges for better belt life and hard anodized for durability. Laser-etched degree markings assist in engine tuning. High-quality fasteners and a heli-coil thread insert in the ring gear allow for secure tightening and multiple adjustments without thread wear.
