FOAM CELL TECHNOLOGY – Micro-Cellular closed cell foam insert maximises cooling efficiency by occupying less internal space than gas within a pressurised shock absorber. Greater oil capacity and more surface area maintains lower operating temperatures.x40-45mm TEFLON BANDED PISTON – Precision shim-stack piston specifically valved by Ironman suspension engineers, banded with teflon for smooth long life operation. 60-72mm TWIN TUBE BODY – 50%-100% more oil volume than a gas shock absorber for superior cooling and endurance. Twin tube construction protects internal components from rock damage. 18-20mm 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 oil retention ability to withstand high displacement offroad use. SUPPLIMENTARY WELDED MOUNTS – Fusion welded then supplementary welded for higher strength and reliability. 360° WELDED MOUNTS – Fusion welded then fully welded around mounting 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. LONG 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.
