Engineered Lift Without Sacrificing Tow Capability

The ICON dual rate coil springs provide 2.5 inches of front lift over stock without requiring driveshaft modifications or any cutting, drilling, or welding. Towing capacity is unchanged from stock, making this system a practical choice for trucks that haul regularly. Application-specific alignment cams are included to restore proper caster geometry after the lift, a step that many aftermarket systems leave to the owner to source separately.

Matched Front and Rear Shock Tuning

ICON 2.0 Aluminum Series internal reservoir shocks are included for both the front and rear axle, tuned as a matched set with the springs. The internal reservoir extends shock stroke before fade sets in, which matters on washboard roads and rough construction-site terrain where repeated small hits accumulate heat quickly. The result is increased wheel travel and reduced body roll compared to stock, with a highway ride character that does not feel stiff or punishing.

Rear Compliance and Axle Wrap Reduction

The rear of the system uses ICON leaf spring expansion packs, a 1-inch cast block kit, a 2-inch rear bump stop spacer kit, and a 12-inch U-bolt kit. On F-250 models, this combination adds approximately 0.5 inches of rear lift over stock. On F-350 models, the rear ride height sits approximately 0.5 inches below stock due to differences in the OEM rear spring setup, a fitment-specific detail worth confirming before ordering. The expansion packs are designed to reduce axle wrap under acceleration and improve compliance on uneven surfaces.

Specifications

Who This Is For and Isn't

This system suits owners of 2011–2016 Ford F-250 or F-350 Super Duty 4WD Diesel trucks with single rear wheels who want a bolt-on 2.5-inch front lift that preserves towing capacity and improves ride quality on rough terrain and highway alike.

This system does not fit F-250 or F-350 gas engine models, dual rear wheel configurations, F-350 Cab and Chassis models, or any Ford Super Duty outside the 2011–2016 model years. An adjustable track bar (sold separately, ICON part 64039 track bar bracket recommended) may be needed to correct bump steer geometry after installation.

Common Questions

Does this system require any cutting, welding, or driveshaft modifications?

The ICON Stage 1 Suspension System for 2011–2016 Ford F-250/F-350 4WD Diesel is a 100% bolt-on system. No drilling, cutting, welding, or driveshaft modification is required for installation.

Will this system work on my F-350 with dual rear wheels?

No. This ICON Stage 1 system fits single rear wheel models only. It is not compatible with F-350 dual rear wheel configurations or F-350 Cab and Chassis models.

How much rear lift does this system add?

The rear lift result differs by model. On F-250 trucks, the rear expansion pack and block combination adds approximately 0.5 inches of lift over stock. On F-350 trucks, the rear ride height sits approximately 0.5 inches below stock due to differences in the OEM rear spring setup.

Does this system work with gas engine F-250 or F-350 models?

No. The coil springs in this ICON Stage 1 system are rated for diesel engines only. A separate ICON system is required for gas-powered F-250 and F-350 Super Duty trucks.

What is included in the system, and do I need any additional parts?

The ICON Stage 1 system includes dual rate front coil springs, two 2.0 Aluminum Series internal reservoir front shocks, two 2.0 Aluminum Series internal reservoir rear shocks, two rear leaf spring expansion packs, a 12-inch U-bolt kit, a 1-inch cast block kit, a 2-inch rear bump stop spacer kit, and alignment cams. An adjustable track bar and track bar bump steer bracket are recommended separately to fully correct axle alignment and bump steer geometry.
