Toytec BOSS Suspension System Fits all; 2003-2009 Toyota 4Runners and 2007-2009 FJ Cruisers.
Designed for the best overall ride comfort and performance in mind, this complete lift kit is the best lift on the market.
ToyTec’s new BOSS front coilover is designed with a larger 5/8” Nitro steel shock shaft which is much more corrosion resistant than chrome plating and is valved specific to your Toyota. This improves overall handling and performance. The threaded Clear-Blue Chromate zinc plated steel shock body is adjustable from 0-3” of front lift height and can be fine tuned to level your truck side to side and front to back. The shocks have a 200 psi gas charge and each shock is dyno’d before it is shipped.
Upper mounts and adjustment rings are machined from 6061-T6 Billet aluminum and are then anodized black to prevent corrosion. Long handled TIG welded spanner wrenches are included for easy adjustment.

TAC-DR-05 - When installing a lift on the front of a 4wd 4Runner, the angles of the front CV axles will increase the higher you lift it. At 3 inches of lift, the CV joints will operate at considerable angle which will increase wear on the CV joints and the rubber boots. The front differential drop kit will reduce the angle placed on the CV axles thereby reducing wear on those components.
Rear Toytec BOSS shocks are optimized for maximum travel with Superflex coils
