The remote reservoir 2.5 shocks give you that plush ride you’re looking for while staying cool and consistent under pressure. You also get dual steering stabilizers to tame oversized tires, and an adjustable track bar that keeps everything dialed in even when terrain gets unpredictable. If your truck needs to do more than just look good in the driveway, this kit brings the muscle to match the mission. It’s a full-package upgrade built for trucks that never stay parked for long.

Complete Suspension Control For Demanding Applications

The ICON Stage 4 4.5" Suspension System is engineered for gas-powered Super Duty owners who need serious performance without compromising everyday usability. At the core are dual rate coil springs designed for precise control and comfort across changing terrain, delivering increased wheel travel and better bottom-out resistance during off-road use. Front and rear 2.5 Aluminum Series shocks with remote reservoirs allow for cooler operating temps and better shock response, especially on long drives or technical trails. Radius arm drop brackets restore proper caster and alignment after lifting the front end, while the included adjustable track bar helps center the front axle and reduce bump steer. The dual opposing 2.0 steering stabilizers are specifically built to counteract the feedback caused by larger tires, giving you better steering feel both on and off the road. Out back, heavy-duty fabricated 5-inch lift blocks and extended U-bolts deliver rear height without sacrificing strength under load. Stainless steel braided brake lines and other high-quality components round out the system, ensuring everything works together as a complete performance package.
