The Eibach Pro-Truck Stage 2 kit for the 2003–2009 4Runner V6 4.0L is a matched package: Pair of Front Coilovers + Rear Shocks + Rear Springs. The front units are threaded-body 2.0-inch coilovers, so you can set front height after installation instead of living with one fixed lift. Each unit is individually dyno tested for matched performance, and the heavy-duty bushing system is cycle tested. Buyers comparing a 4th gen 4Runner adjustable coilover lift against a basic spring-and-shock swap get front height control and a damper setup built for rough terrain.
The main reason to pay for this kit over a cheaper spring and shock package is adjustability. The manufacturer says the threaded bodies allow fine-tuning of ride height and improved damping performance, which matters if you run larger tires or load the truck for overland trips. Eibach states the front coilovers are engineered, tested and manufactured in the U.S.A. Searches for 03-09 4Runner Stage 2 coilovers, adjustable front ride height, and E86-82-073-01-22 usually come from owners who want a documented lift that still handles on pavement.
Application is listed as 2003-2009 Toyota 4Runner V6 4.0L 2WD/4WD w/X-REAS, so confirm your truck's suspension configuration before ordering. The front lift range is +1.5in to 4in, with 0 to 1.5in at the rear. Owners searching for a 4Runner Stage 2 lift kit or 2003–2009 4Runner rear sport shocks with lift springs will find the complete kit described here.
The manufacturer's kit listing describes a pair of front coilovers, rear shocks, and rear springs, so you do not need to source rear components separately.
The manufacturer lists this kit under the 2003-2009 4Runner V6 4.0L 2WD/4WD application with X-REAS. Confirm with the manufacturer that your trim and suspension setup match that listing before ordering.
Details vary between sources. The manufacturer's page for the related 2.0 front coilover lists a two-year warranty, but other sources give different terms, so confirm the current warranty directly with the manufacturer.
The manufacturer's install sheet for the sibling 2.0 front coilover on this generation says use of a hoist and screw jack is highly recommended and will substantially reduce installation time. It also warns that you should never work on or under a vehicle unless it is properly supported. Expect to disconnect the wheel speed sensor, tie rod, and ball joint, and strap the knuckle to the chassis to ensure the lower control arm doesn't fall. Do not use impact wrenches or impact guns to install or remove shock absorber piston components, shafts and piston rod nuts. Torque to factory specification, and after installation, inspect and adjust wheel alignment, tire and fender clearance, brake line clearance, and ABS sensors.
