Product Details

The Wilwood GP310 is a high-performance 4-piston rear sprocket brake caliper engineered specifically for custom motorcycle builds. Constructed from billet aluminum and finished in a durable black anodized coating, the GP310 delivers race-proven stopping power with the clean, purposeful aesthetics demanded by custom builds.

Designed as a right-hand caliper, this unit features four 1.25" stainless steel pistons clamping a .35" disc, combining the thermal management and corrosion resistance of stainless with high-temperature piston seals for consistent performance across a wide operating range. The seals are engineered for controlled retraction, minimizing residual drag for a cleaner, more responsive brake feel.

Key Features:

  • 4-piston billet aluminum caliper with black anodized finish
  • Right-hand (R/H) mounting orientation for rear sprocket brake applications
  • Four 1.25" stainless steel pistons — reduces brake fade and resists corrosion
  • .35" disc compatibility
  • Compatible with 48-tooth and 51-tooth rear sprocket configurations
  • High-temperature piston seals for extended service life and drag-free operation
  • Exclusive pad anti-rattle clip for noise-free performance
  • Bright-finish bleed screws and hardware included
  • Brake pads formulated for broad temperature and environmental ranges
  • Stainless steel rotor-compatible pad compound
  • Bolt-on installation with bracket-mounted caliper design

The GP310 sprocket brake system brings Wilwood's motorsport engineering heritage to the custom motorcycle market, offering a clean bolt-on upgrade that integrates both performance and style. Available in polished or black finish to suit any build aesthetic.

easy to to search for items

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.

Lowest prices of what I was looking for and super fast shipping!!
