Russel floating brake disc.

Floating

RUSSELL BRAKE DISCS FOR BIG TWIN & SPORTSTER

Available in your choice of Satin Finish, Pro Polish or Floating type.
Satin finish discs have a machined surface and are a good economical choice for OE replacement.
Pro Polish discs feature an exclusive EFS® (extremely flat surface) finishing process that produces a mirror finish that has a near perfect flatness providing zero disc runout.
Floating discs have a machined satin disc surface with a chrome plated mounting center. The two pieces are separated by spring loaded retention spacers that provide a rattle free self alignment function. The floating effect helps to eliminate disc warpage by not transferring heat to the center.
All discs are made from 420 stainless steel (SVS420JZ) that provides superior durability with excellent resistance to oxidation.
The discs longevity is achieved by a high frequency induction hardening process prior to the final surface finishing process.
Precision placement of holes provide improved heat dissipation, water dispersion and reduced unsprung weight.
Compatible with all types of brake pads including the OE type sintered metal, Kevlar® or organic.
Can be used with the OE mounting hardware or our chrome plated hardware kits.
All discs are sold each.  Prices include shipping*.
