A high performance rear coil spring manufactured by the best, Eibach Spring. Provides approx. 1? of lift and a comfortable 12% increase in spring rate on the 2003-2009 4-Runner’s and 2007-2014 FJ Cruiser’s. For overland and camping rigs, these springs give you the load capacity needed while increasing wheel travel and improving on and off-road handling. Lifting the rear also increases up travel for better bottoming resistance and running a taller tire will also increase needed ground clearance when off-roading.
