Arb3506 Old Man Emu Front Coil Spring Set for Ineos Grenadier
Engineered with a progressive rate design and chromium-alloy steel construction, the ARB3506 Old Man Emu front coil spring set directly replaces factory units to restore baseline ride height while resisting sag under roof racks, winches, and camp gear.
-
Zero-Modification Bolt-On Fit: Curved to match the Ineos Grenadier’s exact upper control arm mounting cradle, requiring no cutting, drilling, or custom fabrication hardware.
-
Progressive Spring Rate: Loosely wound coils flex over pavement seams and small rocks, while tightly spaced windings engage under heavier loads to limit chassis dive and maintain headlight aim.
-
Fatigue-Resistant Material: Heat-treated chrome-moly alloy wire, shot-peened and gas-charged to reduce internal friction, prevent premature settling, and guard against moisture ingress.
-
Restored Steering & Brake Tracking: Returns proper suspension travel parameters lost to factory drop, improving turn-in response and reducing uneven shoulder wear on all-terrain tires.
-
Precise Enclosure Dimensions: Overall spring length measures 21 inches with a compressed profile of 14.5 by 7.2 inches; the front pair weighs 24.5 pounds and clears factory sway bar end links.
-
Balanced Rear Compatibility: Spring constants calibrated to pair smoothly with Old Man Emu Nitrocharger shocks and rear leaf or airbag upgrades, eliminating front-rear mismatch on choppy trails.
Replacing worn or collapsed stock coils eliminates bouncing, improves tow stability, and reinstates the vehicle’s designed center of gravity. Professional wheel alignment is required after installation to recalibrate camber, caster, and toe specifications. This assembly is covered by the manufacturer’s limited warranty against structural failure or winding defects.
