Radial Mount 6-Piston Brake Caliper

A CNC billet six piston radial caliper that bolts directly to the 108mm mounts used on most aftermarket lower leg sets and front ends.

Six pistons and a radial mount are the two things that separate a serious front brake from a stock one. More pistons spread clamping force evenly across a longer pad, and mounting the caliper radially rather than on an axial lug stops it flexing away from the rotor under hard braking. Hawg Halters machines these from 6061 billet with differential bore technology, which sizes the pistons differently front to back so the pad wears flat instead of tapering.

Features of the Radial Mount 6-Piston Caliper

• Precision CNC machined 6061 billet aluminum construction
• Direct bolt on to the 108mm mounting brackets used by leading custom lower leg sets and front ends
• Differential bore technology for even pad loading
• Dual EPDM copolymer seals and stainless steel pistons
• Quick change design for easy pad maintenance
• Dual hidden bleeders for easy bleeding
• Stronger and more rigid than a stock caliper while weighing less
• Ships complete with chrome grade 8 hardware and fittings
• Install parts for both 11.8 inch and 13 inch rotors are included
• Made in the U.S.A.

Radial Mount Caliper Fitment

For Harley-Davidson front ends with 108mm caliper mounting brackets. That covers most aftermarket performance lower leg sets and custom front ends, and it is the mount pattern rather than the model year that determines fitment.

Sold individually. Left and right are different parts, so order both if you are running dual discs. Offered in chrome and black.

Important Notes

• ⚠️ VERIFY that your lower legs use 108mm caliper mounts before ordering. This caliper does not bolt to a stock Harley-Davidson lower leg without the correct bracket.
• Brake work should be done by a qualified technician and the system bled properly before the bike is ridden.

Common Questions About the Radial Mount Caliper

Will this fit my stock front end?
Not on its own. It is cut for 108mm radial mounts, which is what aftermarket lower leg sets and custom front ends use.

Do I get a left and a right in one order?
No. They are separate part numbers. A dual disc front end needs one of each.

Which rotor size does it take?
Both. The install parts for 11.8 inch and 13 inch rotors are in the kit.
