Before you shop, one fact decides half of this purchase: the FJ Cruiser’s front suspension is a coilover strut, not a plain shock. The rear takes a conventional shock. That means a “full set of shocks” is really two different parts, and a front unit either arrives as a bare shock body that has to be assembled onto your spring with a spring compressor, or as a preassembled coilover you can bolt straight in. Getting this wrong is the most common ordering mistake on this vehicle. The second decision is whether you are lifting. Most FJ owners buying shocks are also adding an inch or three of height, and a shock valved for stock ride height will run out of travel and wear out early on a lifted truck. Ten options below, from a straight OE replacement to competition-grade remote-reservoir hardware, with what each actually suits.

The picks, in detail
Bilstein 5100 Series
The default FJ Cruiser upgrade and the value benchmark. The front unit has snap-ring grooves at multiple heights, so it sets your lift without buying new springs.
- Monotube gas-pressure design, 46mm digressive piston
- Front has multiple snap-ring positions for 0 to about 2.5 inches of lift
- Zinc-plated body, yellow boot
- Sold individually; front units need spring compression to assemble
- Lifetime limited warranty
- Roughly $300–$400 for a full set — the cheapest real improvement over stock
- The adjustable front height means a modest lift costs nothing extra
- Reduces body roll noticeably; the best choice if you tow or haul
- Firmer than stock to the point of harshness over speed bumps and broken tarmac
- Lifting via the snap ring preloads the stock spring, which stiffens the ride further and costs down-travel
- Not rebuildable — when it fades, you replace it
Bilstein 6112 Front / 5160 Rear
The grown-up Bilstein answer. The 6112 is a proper preassembled front coilover with its own spring, and the 5160 adds a remote reservoir at the rear for heat capacity.
- 6112 front coilover ships assembled with a spring — no compressor needed
- Adjustable front lift, typically 1.5 to 3 inches
- 5160 rear uses a remote reservoir to separate gas from oil
- 60mm front piston, larger than the 5100
- Commonly sold as a kit paired with OME rear springs
- Solves the 5100’s two real weaknesses at once: no spring compressor, and a correct-rate spring instead of a preloaded stock one
- The rear reservoir genuinely resists fade on long washboard roads
- Bolt-in installation in an afternoon
- Roughly triple the price of a 5100 set
- The reservoir needs mounting and hose routing at the rear
- Overkill if the truck never leaves pavement
Old Man Emu Nitrocharger Sport
ARB’s overland-tuned damper, designed around a loaded truck. If your FJ carries a roof tent, drawers and recovery gear, this is valved for the weight you actually have.
- Nitrogen gas-charged twin-tube design
- Valving matched to OME’s own spring rates
- Sized for the standard OME lift heights
- Designed and tested for sustained corrugated-road use
- Widely available as a complete matched lift kit
- Rides better loaded than unloaded, which is the opposite of most shocks and exactly right for overlanding
- Buying OME shocks and OME springs together removes all the guesswork about matching
- Excellent durability record on long-distance dirt
- Twin-tube design fades sooner than a monotube under hard, fast off-road driving
- Can feel underdamped and floaty when the truck is completely empty
- Not rebuildable
Fox 2.0 Performance Series IFP
The compliance choice. Where Bilstein controls the body, Fox absorbs the hit — it takes the edge off sharp impacts better than anything else at this price.
- 2.0-inch aluminium body, internal floating piston
- Rebuildable and rechargeable with nitrogen
- Available in stock-height and lifted valving
- Front sold as bare shock or preassembled coilover
- Race-derived damping curve
- Clearly softer over speed bumps, potholes and rock than the Bilstein 5100
- Rebuildable, so it can genuinely last the life of the vehicle
- Aluminium body sheds heat better than steel
- Typically $500–$600 per set, meaningfully more than the 5100
- Allows more body roll; less suited to towing
- Rebuild service is a specialist job, not a driveway one
King 2.5 OEM Performance Series
The point at which suspension stops being a part and becomes a tuning exercise. Remote reservoirs, adjustable compression, and a rebuild programme that treats these as serviceable equipment.
- 2.5-inch body with remote reservoir
- Available with compression adjusters
- Fully rebuildable and revalvable to your weight and use
- Preassembled front coilovers with matched springs
- Made in the USA, race-proven in desert competition
- FJ forums consistently place King and Fox 2.5 at the top of the hierarchy
- Revalving means the shock can be re-tuned when you add bumpers and a winch
- Enormous heat capacity — effectively fade-proof at any speed a road-legal FJ will reach
- $1,500–$2,500 per set, more than many FJs are worth as a proportion
- Requires reservoir mounting and periodic servicing to be worth the money
- Wasted on a truck that mostly commutes
Icon Vehicle Dynamics 2.5 Series
King-tier hardware with a slightly more road-biased tune. The usual pick for people who want a competition shock that is still pleasant on a daily commute.
- 2.5-inch aluminium body, remote reservoir options
- Compression Damping Adjuster available
- Preassembled front coilovers, height adjustable
- Rebuildable with published service intervals
- Sits in the tier between Bilstein and King on FJ forums
- More civilised on pavement than most 2.5-inch race shocks
- Height adjustability lets you fine-tune rake after adding a steel bumper
- Strong dealer and rebuild network in the US
- Premium pricing, and the adjusters add more on top
- Coilover preload adjustment is easy to get wrong and hurt ride quality
- Like all 2.5s, needs the reservoir mounted properly or hoses chafe
Rancho RS9000XL
The one shock here you can retune from outside the vehicle. Nine manual damping positions means one set covers empty commuting and a loaded weekend.
- Nine-position externally adjustable compression damping
- Twin-tube gas-charged design
- Optional in-cab remote adjustment kit
- Available for stock and lifted heights
- Long-standing 4×4 aftermarket product
- Genuinely useful adjustability — soften it for the highway, stiffen it for a loaded trip
- Reasonably priced for what it does
- Easy to dial in without removing anything
- Even at its firmest it does not match a monotube for body control
- Twin-tube construction fades on sustained hard off-road running
- You have to crawl under the truck to adjust unless you buy the remote kit
Dobinsons IMS and MRA
An Australian outback brand with the same design brief as OME but a monotube option, which is the gap in OME’s lineup.
- IMS is a three-stage variable-valving monotube
- MRA offers a remote-reservoir option at moderate cost
- Tuned specifically for heavily loaded touring vehicles
- Matched Dobinsons spring range for the FJ
- Designed for sustained corrugation
- Monotube heat resistance with overland-oriented valving — a combination that is otherwise expensive
- Remote reservoir at well under King or Icon money
- Well regarded on Australian and South African touring forums
- Thinner US dealer network; parts and support can be slower
- Less brand recognition affects resale
- Fewer independent reviews to check against
Toytec Boss Adjustable Coilovers
A Toyota-specialist house brand, sold preassembled and pre-tuned for the FJ. The convenience option in the mid-upper tier.
- Preassembled front coilovers with matched springs
- Height adjustable across the common lift range
- Aluminium bodies, some models with reservoirs
- Sold as complete FJ-specific kits
- Toyota-only vendor with model-specific support
- Everything arrives matched and assembled — no parts-picking, no spring compressor
- Vendor support actually knows the FJ Cruiser specifically
- Sits in the well-regarded tier between Bilstein and King
- House-brand hardware often manufactured by another company; verify what you are getting
- Less resale value than a King or Fox badge
- Kit pricing can hide how much you are paying per corner
KYB Gas-A-Just
The honest budget answer. If your original shocks are simply worn out and you have no intention of lifting, this restores the truck to how it left the factory for very little money.
- Monotube high-pressure gas design
- Direct OE-replacement fitment, no modification
- Stock ride height only
- Widely stocked at general auto parts retailers
- Among the lowest-cost monotubes available
- Cheapest way to fix a genuinely worn suspension
- Monotube design at a twin-tube price
- Available same-day at most parts stores
- Slightly firmer than the original Toyota unit and some owners notice it
- No adjustability and no lift capability at all
- Not built for repeated hard off-road use
Buying tips
- Decide the lift height before you decide the brand. Almost every shock here is sold in stock-height and lifted valving, and they are not interchangeable. A stock-length shock on a 3-inch lift becomes the thing that limits your droop travel, which is both a worse ride and a way to tear a shock apart.
- Front is a coilover strut, rear is a shock. A bare front shock body has to be assembled onto your existing spring with a spring compressor — a genuinely dangerous job with the wrong tool, and one most shops charge for. Preassembled coilovers (Bilstein 6112, King, Icon, Toytec) cost more precisely because they remove that step. Factor the labour in before comparing prices.
- Match shocks to springs, not to a brand you like. A shock is a damper for a specific spring rate. OME shocks with OME springs, or King coilovers with King springs, will out-perform a more expensive mismatched combination. If you already have springs, tell the vendor which ones.
- Monotube versus twin-tube is the real technical divide. Monotubes (Bilstein, Fox, King, Icon, KYB) separate gas and oil and shed heat better, so they resist fade on long dirt roads. Twin-tubes (OME Nitrocharger, Rancho) are more compliant at low speed and cheaper. Neither is better in the abstract — it depends on whether your problem is washboard or potholes.
- Weigh the truck as it actually sits. Steel bumpers, a winch, sliders, a drawer system and a roof tent easily add 400–500 kg, and that changes which spring and valving you need. Suspension chosen for a bare FJ will sag and ride badly once the build is finished. Buy for the finished truck, not the current one.
- Replace them in pairs, per axle, always. A new shock on one side and a worn one on the other creates a genuine handling imbalance, most noticeable under braking on a rough surface. If money is tight, do one complete axle now and the other later rather than one corner at a time.
- Budget for an alignment afterwards. Any change in ride height alters caster and toe on this platform. Skipping the alignment will wear a set of tyres in a few thousand kilometres, which costs more than the alignment did.
- Check the bushings and the upper mounts while you are in there. FJ Cruisers are old enough now that the rubber is frequently the actual source of the clunk people blame on the shocks. New dampers bolted to perished mounts will still knock.
