Rancho QuickLIFT Leveling Struts With RS5000X Shocks | Fits 1995-2004 Toyota Tacoma 4WD

The Rancho QuickLIFT Leveling Struts with RS5000X shocks kit (RS999907, RS999908, RS55180, RS55226) is a factory-style, vehicle-specific suspension upgrade engineered to remove factory rake, restore correct stance and improve ride control for 1995–2004 Toyota Tacoma 4WD trucks. The system pairs Rancho’s QuickLIFT front loaded strut assemblies (pre-assembled strut, coil spring and upper mount) with matched RS5000X gas shocks for the rear (separately keyed RS55180 for rear right and RS55226 for rear left) so the truck rides balanced front-to-rear under load and during dynamic driving. Front QuickLIFT struts arrive pre-assembled for fast bolt-in installation with no cutting or frame modifications and use Rancho’s proven valving and coil spring rates to provide firm control while keeping a compliant, daily-drivable ride. The RS5000X rear shocks employ a twin-tube, nitrogen-gas pressurized design with increased fluid capacity and Rancho’s proprietary valving for reduced shock fade, improved damping consistency, and better wheel control across a range of speeds and terrain. Built from heavy-gauge steel with durable finishes and backed by Rancho’s warranty program, this matched four-corner kit is ideal for Tacoma owners who want corrected stance, the ability to run larger tires, and improved on/off-road control while retaining a largely OEM installation experience.
