Ironman 4x4 2022+ Tundra Rear Foam Cell Pro Shocks (Pair)

Loading down the bed of a 3rd Gen Tundra with camping gear, tools, or a bed rack and rooftop tent puts immediate pressure on the factory rear dampers. On washboard Forest Service Roads and sustained off-road treks, stock oil-and-gas shocks rapidly overheat, leading to aeration, uncontrolled rebound, and harsh shock fade. The Ironman 4x4 Foam Cell Pro Performance Rear Shocks are built to resolve these exact handling limitations. Utilizing micro-cellular foam technology to separate hydraulic oil from gas, these shocks maintain maximum oil capacity to eliminate thermal breakdown and deliver consistent rear-end control under heavy loads.

Key Features

• Thermal Endurance & Zero Fade: Micro-cellular foam cell technology prevents oil aeration and cavitation, holding performance steady even when cycling continuously under high operating temperatures.
• Protective Twin-Tube Construction: Built with a 3mm steel outer wall and a 2.4-inch shock body, the twin-tube design safeguards internal valving against rock strikes and severe trail impact.
• Heavy-Duty Internal Components: Features a 20mm hard-chrome piston rod, 45mm internal piston, and single-piece billet eye rings to withstand heavy side-loading without flexing or failing.
• Tundra-Specific Valving: Valved specifically for the 3rd Gen Tundra rear suspension dynamics to maintain smooth highway damping without sacrificing off-road stability.
• Fully Serviceable: Engineered to be fully rebuildable and serviceable, making it a long-term upgrade rather than a disposable factory replacement.

What’s Included

• 2x Ironman 4x4 Foam Cell Pro Performance Rear Shocks
• High-durability natural rubber bushings and top stem mounting hardware
• Replaceable impact stone shield

Pro Tip: Suspension components should always be upgraded as a balanced system. When installing these rear shocks alongside front coilovers, always replace rear shocks in pairs. If you frequently tow or carry significant static weight, consider pairing these with upgraded rear coil springs or leaf packs to maintain proper ride height and prevent premature bump-stop contact.
