Toyota 4Runner King Shocks OEM Kit Models
The following King OEM suspension upgrade kits are available for the 1996 through 2002 Toyota 4Runner:

**Coilovers set for 1.5-3" over stock height depending on year and configuration.**
**Rear shocks fit factory rear springs with up to 3" lift.**

Important Vehicle Specific Notes and Recommendations

Toyota Tacoma Gen. 3 4Runners are extremely popular and Filthy Motorsports works with customers every day doing everything from simple King shock replacements (like this kit), to full race-spec long travel kits, and many solid axle swaps. These trucks are an excellent platform, but there are a few very important tips that we have to keep in mind to build them well:

1. Gen. 3 4Runners had a wide variation in ride heights and fender flare styles from the factory so determining the amount of lift available from your front coilovers will depend on the model year and configuration of your particular 4Runner. Filthy Motorsports and King shocks ship their coilovers preset for the ideal mid-shaft ride height for the best overall performance. The coilovers should not be pre-loaded more than an extra 1/2" of lift at the tire and setting the proper wheel alignment after the installation is critical.

2. The front suspension geometry is very tight with about 7.5" of wheel travel leveraged to about 4" of movement on the coilover. This leaves plenty of room inside the coilover cylinder for King to run an internal reservoir (IFP), yet it also makes the suspension very sensitive to ride height positioning. For the best performance, the coilovers should be set at mid-shaft plus or minus 1/2" compared to stock height. For added movement, an aftermarket upper control arm (UCA) can be used to allow for an extra 1/2" of down travel when the coilovers are built with the extended travel option.

2. DO NOT use coilover pre-load to lift the vehicle over 2.5" to 3" of lift. Even at those heights, and aftermarket UCA and differential drop is required and the tires must be properly aligned to retain good ride quality. The factory geometry works best at about 1.5" to 2" over stock and lifting it more than that puts the CV shafts, steering linkages, tie rod ends, and control arms at steeper angles which reduces ride quality significantly and causes those components to wear out faster. For these reasons, if you want more than 2.5" to 3" of lift AND excellent performance, you will need an aftermarket lift kit that drops the lower control arm and front differential.

Complete Suspension Upgrade Recommendations

Improving the performance and handling of a Gen. 3 Toyota 4Runner can be done in many ways on many different budgets, however, it's always best not to spend your hard earned money twice to get your desired results. With that in mind, Filthy Motorsports recommends choosing one of the following options:

1. Best Performance on a Budget: [ $1,745 Delivered ]
If you don't have a lot to spend and your 4Runners will be your daily driver, we recommend these King coilovers up front and King shocks in the rear with factory front upper control arms and factory rear springs.

2. Best Trail Runner Performance on a Budget: [ $2,322 to $2,440 Delivered ]
For those that want the best performance off-road and on the trails, Filthy Motorsports recommends these King OEM coilovers up front built with extended travel and paired with SPC Upper Control Arms. In the rear we recommend 1.5" lift spacers or your choice of 3" rear lift springs paired with these rear King shocks. If you plan to add a significant amount of weight in the form of bumpers, armor, and gear, we'll increase the front coilover spring rates as needed.

3. Best Desert Racing Performance on a Budget: [ $2,730 to $2,930 Delivered ]
For the ultimate in ride quality on and off-road while maintaining a reasonable budget, we recommend King OEM coilovers up front built with extended travel and paired with SPC or Camburg upper control arms, and a 1" differential drop. For the rear, a set of 3" rear springs and these rear King shocks with compression adjusters will round out the package and allow for maximum suspension travel, adjustability, and proper wheel alignment.

4. Race-Spec Long Travel:
For the ultimate off-road racing suspension, contact Filthy Motorsports about a long travel suspension system with coilovers, bypasses, and hydraulic bump stops.

Remember, all orders are treated as custom orders and we will review the spring rates, valving, and configuration to make sure they not only fit the vehicle, but also match your expectations and goals.

Free Spring Exchange Program: All King OEM Coilover Kits are covered by the Filthy Motorsports Free Spring Exchange Program. While we always do our best to select the proper spring for your vehicle, if the ones we send you settle the vehicle too high or too low, let us know and we'll swap them out for you.

King Compression Adjusters Upgrade
Add 16 levels of compression valving adjustments to your King OEM shocks with King's proprietary compression adjustable reservoirs. Easily switch from a soft, street-friendly ride to stiff, race-ready valving by simply turning the adjustment knob on the reservoirs. Includes custom valving.

King Internal Bypass (IBP) Upgrade
Upgrade your King OEM shocks with an Internal Bypass that consists of a secondary piston and a tapered metering rod that gradually increases the compression valving during the last few inches of compression travel and ultimately serves as a built-in hydraulic bump stop.

External Bypass Tubes Upgrade
For OEM applications where space permits, up to four externally adjustable bypass tubes can be added for compression and rebound zone tuning. Bypass tubes are placed in strategic areas on the shock and are paired with special valving for the ultimate shock setup.

Custom Colors and Finishes
While the standard King-blue components look spectacular, your custom color and finish options are only limited by your imagination. Available finishes include color anodizing, color powder coating, black zinc coating, chrome plating, and even gold plating. Contact us for pricing.

SPC UCAs SPC Adjustable Upper Control Arms
SPC upper control arms feature a greaseable, heavy duty, zero-play, high-misalignment ball joint for increased down travel and significantly improved durability and are adjustable ± 2.0° in camber and -1.0° to +3.0° in caster for perfect alignment.

Camburg UCAs Camburg Racing Upper Control Arms
Camburg desert racing upper control arms feature welded and heat treated chromoly arms, over-sized uniball joints, and polyurethane bushings or heim joints for added strength, increased wheel travel, and improved long-travel geometry for aggressive off-road driving.

King OEM Performance Shock Upgrade Kits are direct bolt-on replacement shocks and/or coilovers for your vehicle and come custom tuned for the ultimate balance of on-road handling and off-road performance. They include all of the necessary hardware you need for a bolt-on installation that can easily be done over the weekend. Custom length shafts and cylinders are available to work with any brand and size lift kit. Additional options include compression adjusting reservoirs, custom colors, internal or external bypass tubes, and race-spec valving.

Servicing, Tuning, and Rebuilding
All OEM upgrade shocks and coilovers are hand-built with the same parts as all of King's other Performance Race Series shocks. They are completely serviceable, tunable, and rebuildable to last a lifetime and it only requires a few simple hand tools, a few hours, and the appropriate King replacement parts from Filthy Motorsports. If you prefer not to do the work yourself, you can always bring (or send) your shocks to us and we will service them for you.
