On the 5th Generation 4Runner there is a ton of questions about suspensions systems and what people should get to run what tires. I put together this bit of information more as a beginning for people just starting out in the suspension modification game. These are just my recommendations and don’t cover half the available options. Please see [MENTION=66316]1engineer[/MENTION] post about tire fitment here – http://www.toyota-4runner.org/5th-gen-t4rs/156378-5th-gen-tire-fitment-guide.html#post1550444
First you need to identify what suspension system you have:
Standard: What I’ll call regular for lack of a better word, comes with “regular” shocks and springs. It’s a coil-spring independent double-wishbone front suspension with stabilizer bar in the front and a coil-spring 4 link with lateral rod rear suspension with stabilizer bar in the rear.
XREAS: You can identify this by looking at all the shocks, they will have a hose coming off of it. This is a full system dependent on each corner, shocks are cross-linked creating a X pattern, thus the name. More information (Link to
K.D.S.S.: from Harper7 via the service manual.
In the KDSS (Kinetic Dynamic Suspension System), a cylinder is installed to each of the front and rear stabilizer bars. The front and rear cylinder upper chambers and the front and rear lower chambers are each connected by a pipe. The hydraulic circuit is filled with high-pressure suspension fluid. The stabilizer control ECU controls the stabilizer control solenoid valves according to input signals from sensor.More info and links here: Kinetic Dynamic Suspension System - Wikipedia, the free encyclopedia
You can have Standard, or a combination of K.D.S.S. with standard, or you can have XREAS. If you have XREAS and want to keep it you are limited to the top spacer lifts.
If there is a suspension system I missed please pm/reply [MENTION=45399]thebwlife[/MENTION] the info in the format I have below and I'll get it added.
I’ll start with the cheaper systems and work my way up to the more expensive custom systems.
