The 2.0 Adventure Series IFP smooth body shocks give you increased ride quality and the control you need when heading into the unknown. They use Fox's proven damping technology to provide a comfortable on-road ride and predictable off-road handling in a variety of conditions. The large 5/8 inch alloy steel shock shaft adds increased strength and rigidity. The shafts are hard chrome plated and heat-treated to resist pitting and scratches that can damage shaft seals. Fox's Internal Floating Piston (IFP) separates the shock oil from the high-pressure, nitrogen charged gas chamber. The IFP eliminates oil aeration allowing maximum performance from the factory-tuned precision valving. Fox's bolt on, 2.0 Adventure Series IFP shocks provide increased damping in any terrain.
