long-icon-questionWhy Choose Strutmasters?

Why choose the Conversion Kit over replacing the air suspension system on your 2003-2011 Toyota 4Runner X-REAS?

A variety of complicated parts make up an air suspension system. Strutmasters conversion kit eliminates the dependence on these parts to work correctly and together at all times. It simplifies the suspension, so to speak. Our kit includes 2 completely pre-assembled coil-over struts that can be installed with five bolts per strut, two rear shocks, and two rear replacement coil springs that slide right into the preexisting spring seats! The kit takes about one hour per wheel to be installed- your 4Runner will be running in no time. Not to mention the price- the kit saves you a lot of money. Below we have compared the price difference between choosing an active vs. non-active suspension system. There are three price comparisons: that of repairing your active hydraulic suspension at the dealer, that of installing aftermarket active hydraulic suspension parts on your vehicle, and that of removing the faulty active hydraulic headache and installing a brand new coil-over suspension conversion kit (DIY).

long-icon-xIs Your Suspension Failing?

How do I know if my 2003-2011 Toyota 4Runner X-REAS Air Suspension is failing?

A failed or leaking hydraulic suspension in your 2003-2011 Toyota 4Runner X-REAS has some obvious signs that you need to look for. The most common is a sudden noticeable and uneven height difference between sides of the 4Runner. Most drivers notice a sagging rear or front, a “leaning” look from side to side, or perhaps the whole 4Runner looks to be hanging too low to the ground. Take note of the 4Runner’s overall ride height- it should not be too low or too high, and should maintain consistency at all times. If you suspect a bad suspension, check for an illuminated suspension warning message or light on the instrument cluster. If the hydraulic compressor is no longer working or working too hard it will sound loud and jarring. Any of these signs means you may need to repair your suspension. Waiting to get it fixed will only cause more components to wear out.

long-icon-gearVehicle Components

What kind of suspension does my 2003-2011 Toyota 4Runner X-REAS have?

The 2003-2011 Toyota 4Runner X-REAS is built with the following suspension components:

2003-2011 Toyota 4Runner X-REAS Coil Springs(x2)- what we love! Coil springs hold the vehicle up in the rear, but be careful, they are rated for and designed to work with the rest of the suspension system, so when you change hydraulic shocks to passive shocks, then you will need a different rated coil spring that works well with the new type of shocks other

2003-2011 Toyota 4Runner X-REAS Active Hydraulic Struts (x2)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. The hydraulic bag assembled on top of the strut controls the height and weight distribution of the vehicle.

2003-2011 Toyota 4Runner X-REAS Height Sensors (x4)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

2003-2011 Toyota 4Runner X-REAS Hydraulic Lines- tubes that run from a hydraulic pump which carries pressurized fluid from the hydraulic pump to the hydraulic suspension components in order to adjust the height of the vehicle, respectively.

2003-2011 Toyota 4Runner X-REAS Hydraulic Pump- creates/sends pressurized hydraulic fluid to active suspension components. When the hydraulic suspension starts leaking, the pump starts working harder to try to keep the system inflated. By the time hydraulic suspension leaks down completely, sitting the vehicle on its tires, the pump will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the pump still needs to be replaced can be very frustrating, time-consuming, and expensive.

2003-2011 Toyota 4Runner X-REAS Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.
