It doesn’t matter if you are searching for high-end bolt-on shocks that fit your stock 4x4, or if you are building a one-off creation with custom shock mounts, the top-tier aftermarket shock industry is blossoming bigger and brighter than it ever has. We’ve compiled the companies that offer high-performance off-road shocks that fit or can be fit to your 4x4. Most of these companies offer many different shock models, so if you don’t see what you like here, don’t be shy—head on over to the company’s website.
ARB recently jumped into the high-end shock market with the Old Man Emu BP-51 externally adjustable internal bypass shock. The shocks are designed to utilize existing mounting locations on Jeep and Toyota 4x4s to allow bolt-on installation without the need for additional vehicle modifications. The shocks feature a 51mm-diameter bore. In addition to the velocity-sensitive damping, BP-51 shock absorbers also generate damping dependent on the position of the piston within the shock absorber’s body via the bypass design. The bypasses are independently adjustable for both rebound and compression damping. This shock valving combination is said to provide the best of both worlds, with a comfortable and compliant ride during normal driving and a more controlled ride over rough terrain. With increased damping at each end of the stroke, the shock piston slows as it approaches full compression and extension, preventing harsh topping and bottoming out of the suspension. Each shock absorber body is manufactured using aircraft-grade 6061 anodized aluminum to dissipate heat and provide corrosion resistance.
The new Bilstein 8125 Series is said to be designed specifically for the serious off-road enthusiast. The new monotube coilover shocks are available in 46mm (2-inch) and 60mm (2.65-inch) diameters in 8, 10, 12, 14, and 16-inch travel lengths. The company also offers short-body versions of the 60mm coilovers for those who are fitting shocks into confined spaces. Each shock features a zinc-plated threaded body with dual-rate coilover hardware. The remote reservoir with a large -8 AN hose provides greater resistance to heat, and the high temperature seals are said to extend the life of the shock. The shocks cycle via a 22mm case-hardened piston rod and have industry-standard 5⁄8-inch bearings at each end for mounting. The 8125 Series shocks are designed to be owner rebuildable. All components are billet machined and made right here in the USA. There are no cast parts used. Bilstein offers a full line of high-end shocks for custom and race applications as well.
EVO Manufacturing specializes in modifying the ’07-current Jeep Wrangler JK. The company offers several different kits that include King shocks with EVO-spec shock valving for the JK. These kits range from bolt-on adjustable performance shocks that fit stock applications, to complete bolt-on coilover kits and Double Throwdown EVO Lever cantilever long-travel coilover kits with bypass shocks. The shock kits are designed to fit most aftermarket suspension systems for ease of installation on nearly any JK Wrangler. Kits with bypass shocks can be tuned externally to match your driving style or compensate for the weight of extra gear or people in the back of your Jeep.

Fabtech offers a full line of 2, 21⁄4, 21⁄2, and 4-inch high performance Dirt Logic shocks. The company has expanded the line of high-end Dirt Logic shocks to include adjustable piggyback and adjustable remote-reservoir shocks. This new design gives the user the ability to change the compression damping of the shock while on the vehicle. A 10-way knob with detents allows for wide range of adjustments to suit many different driving conditions. The adjuster features the exclusive Fabtech Port Flow system. Shock fluid is channeled through specific-sized ports between the reservoir and shock body, controlling the compression forces of the shock as it cycles. Each detent provides a different sized port for the fluid to pass through. Also new for 2015 is that all Dirt Logic shocks feature a 304 stainless steel body and black NitroSteel piston rod for maximum corrosion resistance.
The FOA OEM shock upgrade kits are said to provide an easy, hassle-free, bolt-on installation for your ’07-current Jeep Wrangler JK. No cutting or welding required. The FOA shock kits are available for Jeep JKs with lifts from 0 to 6 inches. The 2-inch-diameter shocks are made from zinc-plated 1026 steel and feature black anodized aluminum components. Also new from FOA is the External Compression Adjuster available for 2 and 21⁄2-inch shocks. The External Compression Adjuster gives you the ability to adjust compression damping from super soft to super firm with the twist of a knob. This feature can soften your ride when just cruising or firm up the compression when hammering over rough terrain or carrying additional gear.
You’ll find Fox shocks on factory applications ranging from mountain bikes, UTVs and snow machines, to the ’17 Ford Raptor. However, the company offers a full line of aftermarket universal air, smooth-body, coilover, and adjustable bypass shocks, as well as bolt-in performance shocks for many popular 4x4 applications. The latest includes the adjustable Dual Speed Compression (DSC) shocks for the ’07-current Jeep Wrangler JK. The DSC adjusters provide tuning for on-road use while also offering more aggressive damping for use off-road. The simple adjusters increase both low- and high-speed compression levels up to 25 percent, giving you the ability to maximize small bump compliance and traction while still having the extra damping required for big hits.

The STX from ORI Struts is more than just your typical air shock. STX struts are compact, internally bypassed, nitrogen-charged long-travel suspension systems. The light weight struts are said to be designed to handle a high load capacity and control body roll. Each strut features a dual pressurized chamber and other internal features that are said to provide stability in fast turns and on off-camber side hills. The design is said to allow most users to eliminate sway bars, external bumpstops, and limiting straps. Each STX strut can be easily tuned by simply adjusting nitrogen gas pressures. Available in lengths from 8 to 20 inches of travel, the STX struts can support up to 1,900 pounds each. The STX Strut is velocity-sensitive with seven-position externally-adjustable rebound damping. They feature an internal hydraulic bumpstop on the compression stroke, a hydraulic end-of-stroke cushioning at full extension, cooling fins to dissipate heat, a massive 13⁄4-inch piston shaft, and 5,000 psi seals. Both 1⁄2-inch and 5⁄8-inch mounting points are available.
