Engineered specifically for Harley-Davidson V-Twin applications, the All Balls Racing High Torque Starter is constructed entirely from new components to ensure reliable ignition performance. The unit features a 10/32 threaded output shaft, accompanied by a conversion bolt for compatibility with earlier 1/4-20 threaded shafts, covering Big Twin models from 1989 through 2005. Precision manufacturing is evident in the cold-chamber die-cast end frames, which are machined on precision fixtures, while the idler gears are produced from cold-heated steel to withstand high-stress conditions.
Internal components are optimized for durability and power delivery, with armature hairpins resistance-fused to the commutator and clutches utilizing 20% oversize rollers. Depending on the specific variant, the Hitachi starter measures 5.25 inches in overall length, while the Prestolite version is 6 inches long. To maintain the limited lifetime warranty, installation requires the use of a 4 gauge battery cable set to accommodate the increased electrical performance of the unit.
