Foam Cell Pro 3.5" Suspension Kit Suited For Toyota Tundra 2007-2021 - Stage 1

Ironman 4x4 Foam Cell Pro Lift Kit combines upgraded on-road dynamics, dramatically reducing body roll and increasing stability with excellent off-road touring performance.

Our Foam Cell Pro shock absorbers feature a tough, military spec, big bore 3" twin-tube shock, the largest, strongest shock on the market; they are nearly indestructible, carry no internal parts which can jam, require little to no service, and are rebuildable.

The Foam cell pro shock is filled with premium grade FUCHS oil and our foam cell sleeve technology. The foam cell sleeve, impregnated with millions of tiny bubbles of nitrogen, maximizes oil and thermal carrying capacity and eliminates high internal pressures found on regular nitro gas-shock absorbers.

All of these features combined deliver an incredibly reliable, fit for purpose shock absorber that has stood the test of time in the Australian outback and military theaters around the world.

FOAM CELL PRO SHOCKS

FOAM CELL TECHNOLOGY: Increases shock performance & eliminates shock fade by increasing thermal capacity and eliminating high internal pressures.

2.4” TWIN TUBE BODY: Increased oil volume for improved cooling and endurance. Twin tube construction protects internal components from rock damage.

HARD CHROME PISTON ROD: Hardened and polished, volumetrically balanced to piston size.

FLEXIBLE RUBBER BUSHES: Offers quieter operation and reduces damaging side loads from shock absorber.

SUPPLEMENTARY WELDED MOUNTS: Fusion welded and supplementary welded for maximum strength and reliability.

SINGLE PIECE BILLET EYE RINGS AND STEMS: Ultra robust design prevents breakage or bending of mounts.

VEHICLE SPECIFIC VALVING: Every part number is specially valved for each vehicle application, this ensures the best possible ride and handling as intended by Ironman 4x4 suspension engineers.

EXTENDED TRAVEL: Extended travel over OEM suspension. Suitable for standard and raised height vehicles, additional length increases wheel articulation.

IMPACT RESISTANT STONE SHIELD: Steel or Polyethylene dust shield protects piston rod from impacts and road debris.

COIL SPRINGS

ADDED GROUND CLEARANCE: All Ironman coil springs are designed to provide a safe, comfortable ride while also providing additional ground clearance.

ENGINEERED FOR RELIABILITY: Ironman 4x4 coil springs are CNC cold wound and bar peeled for maximum reliability and consistency, every coil spring is ‘shot-blasted’ to ensure long life, preset to its solid height and load tested to avoid spring sag.

POWDER-COATED: All springs are electro-static powder-coated for a gleaming appearance. Available in raised height and perfectly matched to Ironman 4x4 Shock Absorbers.

LEAF SPRINGS

ADDED GROUND CLEARANCE: All Ironman leaf springs are designed to provide a safe, comfortable ride while also providing additional ground clearance.

ENGINEERED FOR RELIABILITY: Ironman 4x4 coil springs are shot peened for maximum reliability and consistency to ensure long life.

INTER-LEAF LINERS: Ironman 4x4 leaf packs include inter-leaf liners to lower friction between leaves reducing noise and improving comfort.

BOLTED GUIDE CLAMPS: Bolted guide clamps for greater flex and addition of inter-leaf liners.

**NOTE**

Ironman 4x4 recommends using an aftermarket UCA like our Pro Forge UCA's when lifting the front of your Tundra over 2.5 inches.

Go any higher, and you risk the OEM Stock Upper Control Arm contacting the "large and in-charge" Ironman 4x4 coil at full droop.

This can lead to scratching or chipping of the coil's powder coat creating a raw spot where rust and corrosion can occur.

NOTE:

• Ironman 4x4’s Foam Cell Pro Coil-overs are some of the largest over-engineered suspension components in the industry. At full steering lock you might notice slight contact between the FCP coil-over’s lower spring seat and the stock steering tie rod boot. This contact is superficial and not a concern.
