BrakeTech AXIS Cobra SS Rear Brake Rotor — 310mm x 6mm, Harley 2000–2026

BrakeTech's AXIS rear floater brings the same full-floating Direct-Link technology as their front rotors to the back wheel — 100% billet construction that runs 10–35% lighter than the OE rotor it replaces (application dependent, per BrakeTech), designed for use with the stock caliper.

FITMENT

Fits 2000–2026 Harley-Davidson models — Touring fitments include Road King, Road Glide, CVO Road Glide, CVO Road Glide ST, Electra Glide, Street Glide, Limited and Ultra (fitment as published by BrakeTech). IMPORTANT: the floater buttons need clearance behind the carrier — some stock wheels don't provide it. Read the installation notes below before ordering, and email us if you're running a stock rear wheel so we can talk it through.

INSTALLATION

BrakeTech's rear floaters require clearance for the floater buttons to extend through the back of the center carrier. Some OEM wheels do not provide this clearance and require compatible aftermarket wheels, and the caliper bracket or wheel hub may need modification for button clearance — confirm your wheel's clearance before installation. No official BrakeTech install video exists for this rotor — installation is manual-only.

QUESTIONS RIDERS ASK

Is a floating rear rotor right for how I ride?
BrakeTech designs the rear floater for light-to-moderate rear brake use, with the front brake doing most of the work. If the rear brake is your primary brake (roughly 40% or more of your braking), BrakeTech recommends a fixed one-piece rear rotor instead.

Will it clear my stock rear wheel?
Maybe not — the floater buttons extend behind the carrier and some stock wheels don't leave room. Check for backside button clearance before ordering; if you're unsure, email us your wheel details and we'll help you confirm.

Does it work with my stock caliper?
Yes — BrakeTech designs this rotor for use with OE calipers.

When will my rotor ship?
These are on backorder at BrakeTech with no published ETA. Ordering reserves yours — we relay it to BrakeTech right away and email tracking as soon as it ships.
