The Falcon 2.1 upgrade
More control behind every mile
Tuned specifically for the Toyota Tundra, Falcon 2.1 Monotube rear shocks provide improved ride quality, stability, and control across daily driving, towing, and off-road conditions.
Large 2.3-inch shock body
Increased oil capacity and improved heat dissipation help manage the demands placed on your rear suspension.
Heavy-duty 3/4-inch shaft
An induction-hardened, chrome-plated shaft brings durable construction to this vehicle-specific rear shock upgrade.
See the stance. Choose your height.
Heavy-duty, application-specific engineering
Built for more than a taller stance
Both systems use laser-cut, CNC-bent, welded, and boxed steel crossmembers engineered to maintain proper suspension geometry while increasing ground clearance.
Steering & suspension geometry
CNC-machined iron steering knuckles retain the factory tie rods. The offset front strut-spacer design adds lift without increasing track width, while a complete differential-drop system helps maintain proper CV axle and driveline angles.
A complete system
OEM-style cast-iron rear lift blocks, extended U-bolts, bump-stop extensions, sway-bar relocation components, and a protective skid plate round out each kit.
