IRONMAN 4X4 FOAM CELL PRO
Foam Cell Pro 2-3" Lift Kit
Heavy-Duty Suspension Built Around Your Tacoma
Fits 2005-2023 Toyota Tacoma applications.
Ironman 4x4 Foam Cell Pro combines large-body twin-tube dampers, pre-built front coilovers, matched rear shocks, upgraded leaf springs and required fitment hardware into a complete suspension system. Choose the front lift and load rating, rear payload rating and Stage that match the way your Tacoma is actually built and used.
THE CAP-IT TAKE
A Complete Tacoma Suspension System, Not Just a Set of Shocks
The strength of this package is the ability to match the suspension to the truck. Front spring choices account for permanent front accessory weight, while Medium and Heavy rear leaf packs let you choose for the payload your Tacoma carries every day.
Foam Cell Pro dampers use a large twin-tube body and foam-cell technology to maximize oil capacity without the high internal gas pressure of a conventional gas shock. The result is a durable, rebuildable damper designed for long-distance touring, rough roads and loaded adventure vehicles.
For most customers, the right kit is determined by permanent accessory weight rather than the maximum load you might occasionally carry. If you are unsure, Cap-it can help choose the configuration before ordering.
Why Foam Cell Pro Is Different
Large-Body Twin-Tube Design
The Foam Cell Pro platform uses a large-volume twin-tube damper body to carry more oil and manage heat during extended rough-road and off-road use.
Foam Cell Technology
A foam-cell sleeve containing microscopic nitrogen bubbles helps control oil expansion while avoiding the high internal pressure used in conventional gas shocks.
Pre-Built Front Coilovers
Application-specific front coilovers arrive pre-assembled in the selected lift and load configuration, simplifying installation and matching the spring to the intended vehicle setup.
Matched Rear Leaf System
Driver- and passenger-side leaf springs, rear Foam Cell Pro shocks, bushings, U-bolts and required spacer hardware complete the rear suspension package.
