Four Inches Of Lift Purpose Built For The FJ40
The Skyjacker L40KS-H is a 4 inch suspension lift system engineered specifically for the 1964-1980 Toyota Land Cruiser FJ40, one of the most capable and enduring off road platforms ever built. Because the FJ40 has a short wheelbase and a unique leaf spring mounting layout compared to domestic trucks, Skyjacker designed this kit around the FJ40's specific dimensions rather than adapting a generic truck kit. The L40KS-H pairs Hydro shock absorbers with front and rear leaf springs and U-bolt kits to deliver 4 inches of lift all around, improving approach and departure angles for technical trail driving while keeping the FJ40's classic proportions intact. This lift height is a popular choice among FJ40 owners who want more tire clearance without pushing the vehicle's short wheelbase geometry too far.
