Ironman 4x4 Nitro Gas Suspension Kits improve ride quality, stability, strength, and handling over the factory suspension.
Perfect for outdoor adventures into the backcountry and back home again without breaking the bank.
Nitro Gas kits provide increased payload capacity so you can bring all of your gear with you to your favorite spots without compromising safety, comfort or performance.
NITRO GAS SHOCKS
NITROGEN GAS PRESSURIZED: Low pressure nitrogen gas dramatically reduces the likelihood of oil aeration and shock fade.
35mm TEFLON BANDED PISTON: Precision shim-stack piston specifically valved by Ironman suspension engineers, banded with teflon for smooth long life operation.
54mm TWIN TUBE BODY: Increased oil volume for improved cooling and endurance, Twin tube construction protects internal components from rock damage.
16mm-18mm 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.
TRIPLE-LIP HIGH PRESSURE NOK SEAL: Maximum gas and oil retention ability to withstand high displacement offroad use.
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 suspension engineers.
EXTENDED TRAVEL: 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.
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 readily available 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.
