Ironman - IM2.5 3" Suspension Lift Kit - Toyota Tundra 2022-Current
Ironman 4x4 IM2.5 Suspension Lift Kit
Give your Tundra a more composed ride on pavement and confident control beyond it. The Ironman 4x4 IM2.5 system combines 2.5-inch monotube shocks, nitrogen pressure, and vehicle-specific tuning for responsive damping across changing terrain.
Build your setup around how you use your truck: choose your suspension stage, then match the rear springs to the weight you carry.
Choose Your Suspension Stage
Stage 1 — Suspension Upgrade
Includes front IM2.5 coilovers, rear IM2.5 shocks, rear coil springs, a differential drop kit, and bump stop spacers.
Stage 2 — Suspension + Upper Control Arms
Includes Stage 1 components plus upper control arms to improve alignment correction on a lifted Tundra.
Stage 3 — Suspension + Upper Control Arms + Panhard Bar
Includes Stage 2 components plus a panhard bar to help restore rear axle centering after lifting.
Front Spring Configuration
All variants on this listing use the 3" Heavy Load front option, rated for 110–240 lbs of additional front weight. Account for your front-mounted accessories when choosing this configuration.
Choose Your Rear Springs
• 1" Light Load — 0–440 lbs: For owners selecting the lower rear lift option within this load range.
• 2" Medium Load — 0–440 lbs: For owners wanting more rear lift within the same listed load range. The difference from Light Load is the listed lift height, not a higher weight rating.
• 2" Medium Load with Accessories — 440–880 lbs: For builds carrying additional rear weight from equipment such as storage systems and regularly carried gear.
• 2" Heavy Load — 880–1,760 lbs: For heavily equipped builds carrying substantial constant rear weight.
Choose springs for the weight that stays on your truck—not an occasional maximum load. Overly stiff springs can compromise unloaded comfort. These ratings do not increase Toyota’s payload or towing limits.
Fitment & Installation
Designed for Toyota Tundra 2022–Current; not compatible with Adaptive Variable Suspension (AVS).
Ironman strongly recommends longer Toyota TRD red CV axles with front lifts of 2.5 inches or more. These axles are not listed among the included components. A professional alignment is required after installation.
Final ride height depends on vehicle configuration and added weight. Confirm compatibility with your truck’s factory equipment before ordering.
