Foam Cell Pro 3.5" Suspension Kit Suited For Toyota Tundra 2007-2021 - Stage 2

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.

UPPER CONTROL ARMS

CASTER CORRECTION: Ironman 4x4 upper control arms are forged with 4 degrees of caster correction for ideal wheel alignment, correcting the vehicle’s geometry back to OEM specs, generating outstanding performance and ride quality.

DROP FORGED CONSTRUCTION: Drop forged construction results in improved strength to weight ratios, increased directional strength with reduced stress concentrations in corners and filets. The precision of drop forging consistently results in superior strength, weight savings, and manufacturing tolerances when compared to machined, rolled, or other cast processes.

HARDENED ZINC COATING: Wrapped in a hardened zinc coating, these UCA’s have up to 75% more corrosion resistance when compared to traditional paint or powder coating. This zinc coating provides maximum effectiveness at warding off the oxidation that typically leads to rust and corrosion.

OEM BALL JOINTS: We use OEM style ball joints and bushings that are tested and manufactured to strict Japanese specifications that are at every dealership and parts store. They feature a fully hardened stud bound in a watertight sealed machined housing which doesn’t allow for contaminates to be introduced into the joint with grease guns or outside environment.
