The IFP eliminates oil aeration allowing maximum performance from the factory-tuned precision valving. That design is the core of the FOX 2.0 Performance Series IFP rear shock, part 980-24-679. It is a single rear unit for Toyota 4Runner applications calling for 2-3 inches of rear lift. The internal floating piston keeps shock oil apart from the high-pressure nitrogen charge, so the performance-tuned valving stays consistent on rough trails and daily driving alike.
Compared with a stock rear shock on a lifted 4Runner, this unit is valved for the vehicle it is sold for. Its black anodized, CNC-machined aluminum body is built to pull heat away faster than steel, which helps the damper hold its composure over long descents and washboard runs. The unit is listed at roughly 7.0 lb, so it adds little unsprung weight for the performance it offers. Shoppers searching for a 4Runner 2-3 inch rear lift shock or an IFP monotube rear shock for Toyota will find it sits in the 2.0 Performance line rather than the entry-level range.
