About this kit
M1 Loaded Strut Pair, fitment-checked
Rough Country 502161_B is a pair of M1 loaded struts covering 2003-2009 Toyota 4Runner 4WD (Limited, SR5, Sport) and 2007-2009 FJ Cruiser 4WD, including the TRD Special Edition and Trail Teams Special Edition. They cannot be stacked with a strut spacer, and they do not fit PRO Series models or anything running KDSS or X-REAS. Carries a 3 Year Limited Warranty.
This M1 loaded strut pair fits 2003-2009 Toyota 4Runner 4WD and 2007-2009 FJ Cruiser 4WD applications listed in the fitment section. Each strut uses a 46mm monotube body with a 46mm digressive piston and an 18mm centerless-ground, chromed rod, with self-adjusting deflective-disc valving handling rebound and compression as the surface changes. Bodies are zinc plated and the bushings are vulcanized natural rubber. Check the exclusions first — KDSS, X-REAS, PRO Series, and any existing strut spacer rule this pair out. Rough Country lists the job at 2-3 hours, and a downloadable installation guide is available.
