The complete dual-seal rebuild kit for HHI's 500-series four-piston calipers — the freshen-up kit for a caliper that's weeping, dragging, or due for service. The 500 series is HHI's differential-bore caliper line, including the rear FLH/FLT caliper kits and the direct bolt-on front calipers.
FITMENT
Fits HHI 500 series 4-piston brake calipers (any model running them). This is the dual-seal version — the 100-series single-seal calipers take a different kit (HHI-101-002).

SPECIFICATIONS
Manufacturer: Hawg Halters Inc (HHI) — part number HHI-501-002
Caliper rebuilds are safety-critical brake work — installation by a qualified service technician is recommended. Follow HHI's published caliper instructions and your Harley-Davidson service manual for disassembly, seal installation, torque and brake bleeding. No official Hawg Halters install video exists for this product — installation is manual-only.
QUESTIONS RIDERS ASK
Does one kit rebuild one caliper? Yes — this is a complete rebuild kit for one HHI 500-series 4-piston caliper.
Will it fit my 100-series caliper? No — the 100 series uses a single-seal design and takes the HHI-101-002 kit. If you're not sure which series your caliper is, email us before ordering.
