FOX IFP-R Adjustable Rear Shocks for Harley Sportster — Street Performance

Upgrade your Harley Sportster suspension with FOX IFP-R V-Twin rear shocks. The Internal Floating Piston (IFP) separates nitrogen gas from the shock oil to maintain consistent damping control over long rides. A wide-range 12-position internal rebound lets you precisely tune rebound to match spring preload, keeping the rear wheel planted and improving stability and comfort.

  • Precise rebound control: 12-position adjustable rebound for fine tuning ride feel and handling.
  • Consistent damping: IFP design isolates gas from oil so damping remains stable ride after ride.
  • Vehicle-specific tuning: Model-specific optimized ride tune with linear spring rates for confident connection to the road.
  • Durable, serviceable construction: 1.5" 6061‑T6 aluminum Type III hard‑anodized body, fully rebuildable and revalvable.
  • Advanced valving: High‑flow, deflective disc velocity‑sensitive damping for controlled absorption of bumps.
  • Quality hardware: 5/8" low‑friction, super‑finished hard chrome shaft; matte black spring and black anodized preload ring.
  • Series & spring: Street Performance series. Standard spring — recommended for rider weight up to 240 lb.
