Elite Engineering: HHI 4-Piston Rear Caliper Kit (2000–2010 Softail)

Give your Softail the braking authority it deserves with the Hawg Halters Inc. (HHI) 4-Piston Rear Caliper Kit. Designed to replace the uninspiring factory rear brake on 2000–2010 models, this kit provides a massive increase in performance by utilizing a high-pressure, 4-piston design that offers superior modulation and heat dissipation compared to the original single-piston floating setup.
The Hawg Halters Advantage

HHI has built a reputation for creating some of the most rigid and effective braking components in the V-Twin industry:

High-Stiffness Billet Construction: Every HHI caliper is CNC-machined from a solid block of aircraft-grade 6061-T6 aluminum. This rigid design prevents “caliper spread” during hard braking, ensuring that 100% of your hydraulic pressure is converted into stopping power at the rotor.

Aggressive 4-Piston Bite: By doubling the number of pistons compared to many factory setups, this caliper provides a larger, more even pressure footprint on the brake pads. This results in shorter stopping distances and a much more linear, predictable feel through the rear brake pedal.

Low-Profile Aesthetics: The HHI design is significantly more compact than the stock assembly, cleaning up the look of your rear wheel and swingarm—perfect for showing off custom wheels.

Precision Fitment for 2000–2010 Softails

This is not a “universal” caliper; it is a dedicated kit designed for the specific geometry of the 2000-series Softail:

Direct Bolt-On Bracket: The kit includes a precision-machined mounting bracket that aligns perfectly with your 3/4″ or 1″ axle (depending on the specific year) and the standard 11.5″ rear rotor.

Finishes to Match Your Build: Choose from a mirror-like Chrome, a sleek Black Anodized, or a Polished finish to perfectly complement your bike’s theme.

Complete Package: Every kit comes pre-loaded with high-friction brake pads and all necessary hardware for a clean, rust-free installation.
