Quick Overview

10+ FJ Cruiser, 10+ 4Runner, 3" Boss Lift - Ultimate
Boss Basic Kit + SPC Light Racing Front Upper A-Arms + Signature Series 7075 Rear Upper and Lwer Control Arms and adjustable Panhard bar

The BOSS Suspension System by ToyTec fits all; 2010+ Toyota 4Runners and 2010+ FJ Cruisers.

Designed for the best overall ride comfort and performance in mind, this is the most complete lift kit on the market.

The 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 spanner wrenches are included for easy adjustment.

We only use Eibach springs for our coilovers which means you have the best name and quality in the business supporting your vehicle.

Our BOSS kit comes standard with RCC2.0 rear springs- These springs offer 2" of lift with stock rear weight with the best overall ride quality and rear articulation.
Choose optional Heavy Duty rear springs from drop down

75109 Toytec BOSS rear shocks are optimized for maximum travel with Superflex coils

Also includes differential drop kit - When installing a lift on the front of a 4wd FJ and 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.

Now includes Toytec Signature series rear bump stop extensions (Pictured)

Coilovers are fully assembled and ready to bolt on. All parts are 100% made in the U.S.A.NEW!
