FOX Factory Race Series 2.5 Performance Elite coilovers and shocks are designed to improve handling, comfort, and suspension control on pavement and demanding off-road terrain. The oversized aluminum shock bodies dissipate heat efficiently, while the increased oil capacity and FOX race-developed high-flow pistons provide consistent damping during extended use.
The adjustable Dual Speed Compression, or DSC, system allows low-speed and high-speed compression damping to be tuned independently for different terrain, driving styles, vehicle loads, and installed accessories.
Diesel-equipped Ram 1500 models carry significantly more front-end weight than comparable V8 models. Because FOX developed these coilovers around the 5.7L HEMI using standard 450 lb/in springs, diesel models or trucks carrying additional front-end weight may require higher-rate springs.
The pictured Ram 1500 4WD diesel used 600 lb/in x 16" Eibach springs and achieved approximately 3" of total front lift with little to no spring preload. This setup was selected with plans for a future front bumper and winch. For diesel trucks without substantial additional front weight, 550 lb/in springs are generally recommended to balance ride quality and lift height.

- 883-06-166: FOX Performance Elite Series 2.5 adjustable reservoir coilovers for approximately 2-3" of front lift. Sold as a pair. Excludes factory air-ride models and requires aftermarket upper control arms.
FOX coilovers are supplied with 450 lb/in x 16" springs as the standard configuration. Higher-rate Eibach springs are available for diesel engines, added accessories, increased front-end weight, or specific ride-height requirements.

Aftermarket upper control arms provide increased suspension articulation and help restore proper alignment on lifted vehicles. Upper control arms are required when using the 2-3" lift coilovers and are particularly important for vehicles lifted approximately 3-3.5".

Timbren helper springs replace the factory frame-mounted jounce stops with progressive-rate rubber springs. They automatically respond to changing load conditions to provide additional support and reduce suspension sag.
Timbren helper springs do not increase the vehicle manufacturer's Gross Vehicle Weight Rating, or GVWR.

TERMS OF WARRANTY
This warranty is conditioned on the FOX suspension product being operated under normal conditions and properly maintained as specified by FOX. This warranty is only applicable to FOX suspensions purchased new from an authorized FOX source and is made only to the original retail owner of the new FOX suspension product and is not transferable to subsequent owners. This warranty is void if the FOX suspension product is subjected to abuse, neglect, improper or unauthorized repair, improper or unauthorized service or maintenance, alteration, modification, accident or other abnormal, excessive, or improper use.
Should it be determined by FOX in its sole and final discretion, that a FOX suspension product is covered by this warranty, it will be repaired or replaced, by a comparable model, at FOX's sole option, which will be conclusive and binding. THIS IS THE EXCLUSIVE REMEDY UNDER THIS WARRANTY.

This limited warranty gives the consumer specific legal rights. The consumer may also have other legal rights which vary from state to state or country to country. Some states and countries do not allow the exclusion or limitation of incidental or consequential damages or warranties, and if dictated by law the above limitations or exclusions may not apply to you. If it is determined by a court of competent jurisdiction that a certain provision of this limited warranty does not apply, such determination shall not affect any other provision of this limited warranty and all other provisions shall remain in full effect.
THIS IS THE ONLY WARRANTY MADE BY FOX ON ITS SUSPENSION PRODUCTS AND COMPONENTS, AND THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION HEREIN.
