Milwaukee Twins OEM-Style Clutch Hub For Harley Big Twin 1998-2006

Durable Drivetrain Restoration: Milwaukee Twins OEM-Style Clutch Hub

The clutch hub is a critical link in your motorcycle’s powertrain, responsible for transferring torque from the clutch plates directly into the transmission input shaft. Over years of high-mileage riding or aggressive shifts, the splines and studs on a factory hub can wear, leading to clutch chatter, poor engagement, or even catastrophic failure. The Milwaukee Twins OEM-Style Clutch Hub for 1998–2006 Harley-Davidson Big Twins is designed to solve these issues. Engineered as a high-quality, cost-effective alternative to expensive dealership parts, this hub (which replaces OEM #37554-98A) is the perfect solution for riders performing a primary drive overhaul. Whether you are refreshing a high-mileage Twin Cam 88 or repairing a damaged assembly, this hub provides the factory-level precision required to keep your Road Glide, Street Glide, or Fat Boy moving smoothly down the road.

Precision Engineering and Heavy-Duty Construction

Milwaukee Twins understands that a clutch hub must withstand immense mechanical stress and heat. That is why this hub is manufactured from high-tensile strength steel, ensuring it can handle the torque output of both stock and mildly modified Twin Cam engines. The internal splines are precision-broached to provide a snug, “no-play” fitment onto the transmission mainshaft, which is essential for preventing shaft wear and ensuring crisp shifting. Furthermore, the clutch plate studs are reinforced to resist shearing and bending under heavy loads. By maintaining strict tolerances during the manufacturing process, Milwaukee Twins ensures that your friction and steel plates slide freely on the hub without hanging up, which is the key to a consistent lever feel and a predictable “friction zone” when taking off from a stop.

A Direct Replacement for 1998-2006 Big Twin Models

This clutch hub is a specific fitment part, covering the final era of the Evolution Big Twin and the first generation of the Twin Cam platform. It is designed to work seamlessly with your existing factory clutch basket, pressure plate, and diaphragm spring.

• Perfect Fitment: Compatible with 1998–2006 Softail, Dyna, and Touring models (except 2006 Dyna models with the 6-speed transmission).
