17-18 Raptor FOX 3.0 Bypass Reservoir Coilover Pair 883-06-140

Raptor FOX 3.0 Bypass Front Coilover Features:

Provides 2 inch front lift
Features massive 3" diameter shock body
Features a black hard anodized finish
Featuring Fox's Dual Speed Compression adjusters for adjusting ride

Huge Improvement in Performance and Fade Resistance with Adjustable Ride Height

We knew it was going to be hard to top the 3.0 Coilovers that came on the 2017-2018 Raptors from the factory, but Fox has managed to do it with their 3.0 Factory Series Coilovers that feature an internal bypass design and recirculating remote reservoirs with a finned design to promote awesome levels of cooling so that your 2017-2018 Raptor never suffers from fade, no matter how hard you push it off-road. The Fox 3.0 Bypass Recirculating Reservoir Coilovers even feature 2" additional ride height so that your Raptor gets a more leveled stance and the clearance to mount up larger wheel and tire combinations. The remote reservoirs are even fitted with Fox's Dual Speed Compression (DSC) adjusters, which allow you to dial in your Raptor's ride quality and performance just to your liking. If you thought the Raptor's suspension performance couldn't get any better, then Fox 3.0 Factory Series Coilovers are here to prove you wrong.

Massive 3" Diameter Shock Body with Recirculating Bridged Remote Reservoirs with Cooling Fins

The Fox Factory Series 3.0 Coilovers are purpose-built to improve the performance of your mighty 2017-2018 Raptor, all while squeezing out just enough extra ride height for a great look and improved tire clearance. The 3.0 Coilover is built around a massive 3" diameter shock body made out of hard anodized aluminum that resists corrosion and aids in heat dissipation. The coilovers feature a 7/8" 17-4 H900 stainless steel shaft that's hard chrome plated for corrosion resistance. Fox carefully tuned the valving inside each coilover in order to provide excellent off-road performance while still maintaining excellent ride quality on the road. The mounts of each coilover are made out of CNC machined 6061-T6 billet aluminum and come standard in a black hard anodized finish. The coilover features a 3.75" race spring that can handle violent articulation and helps adjust ride height with its upper preload collar. The remote reservoirs of each coilover feature a finned design to promote excellent oil cooling, as well as a Recirculating Bridge with two lines that promotes awesome levels of oil flow in and out of the reservoir. The lower mount of the coilover uses a spherical bearing made with PTFE-lined stainless steel. The coilovers are designed to drop right into place of stock and come with installation instructions and hardware.

17 Ford Raptor

Im off-road weekly and love the adjustability of the Fox shocks. Fox has the best customer support if you want to get the most from your vehicle. I would not purchase any other shocks. The team at Stage 3 did a great job in helping me with my purchase.

Can you run 37/13.50/17 with an aftermarket ADD stealth fighter bumper?

Asked by: Gmay - 12/3/2021

That depends entirely on what wheel you're planning to run, specifically its width, offset, and backspacing. An ADD Stealth Fighter bumper will help with clearance, but your best bet would be to call us directly at 623-434-5277 or email us at [email protected] so we can get more specific about your truck.

Can you run 37's with with no rubbing (2018 Raptor)?

Asked by: tigertat - 5/4/2020

Not with the factory bumper, and further rubbing issues may be caused by your choice of wheels. The biggest you can go if you want to avoid chances of rubbing is a true 35x12.50".

Do these require a new upper control arm?

Asked by: csher - 4/3/2020

They do not outright require a UCA upgrade. However, if you are pushing your truck hard enough to require these coilovers, then you may want to consider a UCA upgrade.

How do these compare to the factory 2019 Raptor shocks?

Asked by: Evasive - 6/17/2019

There really is no comparison. The 3.0 Bypass Kit is an all-around superior kit over the stock 3.0s. Between the extra ride height, adjustable ride quality, superior cooling, reduced fade, on-road handling, and off-road performance, the 3.0 Bypass kit outshines the stock coilovers. That being said, Fox makes you pay a pretty penny for the privilege, which is the only (albeit major) downside.

Will these work on a 2018 Raptor with a 4” Fabtech suspension lift?

Asked by: Brad - 9/16/2018

You'd likely run into issues with mounting the coilover's reservoir, and you'd have to reuse the Fabtech Kit's strut and rear shock extensions, but in theory, it would work. I personally wouldn't recommend it.
