Milwaukee Twins OEM-Style Clutch Hub For Harley Big Twin 1984-1989
Milwaukee Twins OEM-Style Clutch Hub: Reliable Restoration for the Evolution Era
When the clutch on your classic Evolution-powered Harley begins to chatter or drag, the culprit is often a worn or grooved clutch hub. The Milwaukee Twins OEM-Style Clutch Hub is specifically designed for 1984–1989 Big Twin models, providing a cost-effective, high-durability alternative to expensive dealership replacements. This hub is the backbone of your clutch assembly, designed to hold your friction and steel plates in perfect alignment for crisp, reliable shifting.
Precision Machined for Smooth Engagement
This clutch hub is manufactured from high-strength steel and precision-machined to ensure that the splines and plate channels are perfectly uniform. Over decades of use, original hubs can develop “notches” from the clutch plates, which leads to a “grabby” feel or difficulty finding neutral. Replacing your worn unit with this Milwaukee Twins hub restores the smooth, sliding action required for effortless clutch modulation.
Ready to Install with Pre-Pressed Bearing
To save you time and the need for specialized shop tools, this hub comes with the main center bearing already pressed in. This ensures that the hub spins true and eliminates the risk of damaging a new bearing during a DIY installation. The internal splines are cut to match the 5-speed mainshaft perfectly, providing a secure, wobble-free connection that handles the torque of the 80-cubic-inch Evolution engine.
Durable OEM-Spec Replacement
Milwaukee Twins understands the importance of maintaining the “stock” feel of a vintage Harley. This hub is built to the exact OEM dimensions (Replacing HD #37550-84), meaning it is fully compatible with your existing stock clutch basket, pressure plate, and springs. Whether you are performing a full engine overhaul or just a mid-season primary service, this hub provides the long-term reliability you expect from a premium replacement part.
Fitment Guide (1984–1989)
This hub is a vehicle-specific fit for the following 5-speed Big Twin models:
- Softail: 1984–1989 (FXST, FLST).
- Touring: 1984–1989 Electra Glide, Tour Glide, and Road King precursors (FLT, FLHT).
- FXR: 1984–1989 Super Glide and Low Rider models.
- Note: Not for use on 1990-later models, which transitioned to the splined-style hub without the tapered keyway.
