Product Description
Ironman 4x4 Foam Cell Pro 3.5" Suspension Kit | Stage 1 (Tundra 2007-2021)
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.

Notes:
** 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.
*** Ironman 4x4 and Offroad Elements recommend using an aftermarket UCA when lifting the front of your Tundra over 2.5". Going any higher you risk the OEM stock upper control arm contacting the Ironman 4x4 coil at full droop. This can lead to scratching or chipping of the coils powder coat creating a raw spot where rust and corrosion can occur.
