ICON Stage 5 Suspension System for 2011-2016 Ford F-250/F-350 7-Inch Lift

The ICON Stage 5 Suspension System lifts 2011–2016 Ford F-250 and F-350 trucks 7 inches in front and 5 inches in the rear, providing clearance for 37-inch tires while preserving factory towing capacity. Front and rear 2.5 Aluminum Series piggyback reservoir shocks with CDCV, dual-rate coil springs, a progressive-rate rear leaf pack, and a fully adjustable 4-link radius arm system are included. Springs are rated for diesel engines only.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Consistent Damping Under Hard Use

The front and rear 2.5 Aluminum Series piggyback reservoir shocks extend the oil volume available during sustained off-road driving, which keeps operating temperatures lower and damping force more consistent over rough terrain than a standard monotube or twin-tube shock. The CDCV (Compression Damping Control Valve) lets the driver adjust ride firmness externally without removing the shock, so the same truck can be tuned for a loaded tow run or an unloaded trail day without tools or disassembly.

Steering and Alignment Geometry Corrected for the Lift

Lifting a solid-front-axle Super Duty without correcting the radius arm geometry introduces bind and accelerates tire wear. The fabricated radius arm drop mounts, track bar drop bracket, forged pitman arm, and adjustable 4-link upper and lower links reposition the steering and axle geometry to match the 7-inch lift height. The result is correct caster, reduced bind through the suspension's range of motion, and alignment figures that fall within spec. No driveshaft modifications are required.

Rear Lift Matched to the Front

The rear 5-inch progressive-rate leaf springs replace the factory pack and are tuned to complement the front coil spring rate. A progressive design means the spring rate increases as load is added, so the truck rides compliantly when empty and stiffens appropriately under cargo or towing weight. U-bolts, a U-bolt plate kit, and brake line brackets are included so the rear installation does not require sourcing additional hardware separately.

• 5-inch progressive-rate rear leaf springs: included with U-bolts and U-bolt plate kit
• Adjustable 4-link radius arm system: fabricated drop mounts, upper and lower links, and 4-link frame bracket kit; minor frame drilling required
• Steering geometry hardware: track bar drop bracket, forged pitman arm, sway bar links, bump stop extensions, and brake line brackets included
• OEM wheel and tire fitment confirmed: 37 x 12.50-inch aftermarket tires fit; larger tires may require fender trimming

Specifications

Who This Is For and Isn't

This system suits 2011–2016 Ford F-250 and F-350 owners running diesel engines who want 7 inches of front lift, 5 inches of rear lift, externally adjustable damping, and a complete geometry-corrected radius arm solution in one purchase. OEM wheels and tires fit the lifted height, and 37-inch aftermarket tires are confirmed to clear without body modification.

The coil springs in this system are rated for diesel engines only and are not suitable for gas-engine F-250/F-350 trucks without additional evaluation; gas-engine models may also require exhaust modification to clear the front driveshaft. Installation requires minor drilling into the frame to mount the radius arm and 4-link frame brackets. Tires larger than 37 x 12.50 inches may require fender trimming. This system does not fit F-250/F-350 trucks outside the 2011–2016 model years.

Common Questions

Do the springs in this system work with gas-engine F-250 and F-350 trucks?

The coil springs included in the ICON Stage 5 system are rated for diesel engines only. Gas-engine 2011–2016 Super Duty models are not a confirmed fit for the spring pack, and those trucks may also require exhaust modification to clear the front driveshaft at this lift height. Buyers with gas-engine trucks should confirm compatibility before ordering.

Does installation require drilling into the frame?

Yes. The radius arm and 4-link frame brackets in this Stage 5 system require minor drilling into the frame to complete installation. This is a permanent modification to the truck's frame rails. Buyers should factor this into their installation planning and confirm their comfort with the procedure before purchasing.

Will OEM wheels and tires still fit after installing this system?

OEM wheels and tires are confirmed to fit the 2011–2016 F-250/F-350 with this 7-inch Stage 5 system installed. For buyers upgrading to aftermarket wheels, ICON specifies 17x8.5-inch wheels with 5.00-inch backspace, 18x9-inch wheels with 5.25-inch backspace, or 20x9-inch wheels with 5.25-inch backspace as compatible fitments.

What tire size does this lift support without body modification?

The ICON Stage 5 7-inch lift system for the 2011–2016 F-250/F-350 is designed to clear 37 x 12.50-inch tires without body modification. Larger tires may fit but will require fender trimming and additional modifications; ICON does not confirm a specific larger size as a no-trim fitment.

Are the shocks serviceable, and can ride firmness be adjusted after installation?

The 2.5 Aluminum Series piggyback reservoir shocks included in this Stage 5 system are fully serviceable. The CDCV (Compression Damping Control Valve) allows external adjustment of compression damping without removing the shock from the vehicle, so ride character can be tuned for different loads or terrain without disassembly.
