PMF 3.5" Alpha Suspension Lift Kit for 2017-2022 Ford Super Duty

Want a 3.5" lift that rides smooth, tows confidently, and stays planted under power?

The PMF 3.5" Alpha Lift Kit delivers a comfortable street ride and added travel up front, plus a rear setup designed to keep factory payload while controlling axle wrap when you’re towing or putting power down. 

• Fits: 2017, 2018, 2019, 2020, 2021, 2022 Ford Super Duty F-250, F-350, F-450
• Intended use: Comfortable daily driving, confident towing, and a stable rear end for higher-HP builds

Why Choose the PMF Alpha 3.5" Lift Kit?

• Smoother ride + more control: Progressive dual-rate coils improve street comfort and provide additional travel vs. stock for better control on rough roads and job sites.
• Towing stability: Rear system retains the OEM leaf pack to maintain payload, then adds a gusseted traction bar kit to reduce wheel hop and axle wrap.
• Dialed stance: Multiple rear block heights let you fine-tune level, slight rake, or a taller rear look.
• Built to last: Heavy-duty links, brackets, brake lines, and track bar components engineered for real-world use.

What’s Included

• Front Coils: 3.5" ICON progressive-rate springs
• Front Links: Short-Arm 4-Link with flex joints or Adjustable 3-Link
• Sway Bar: Heavy-duty replacement sway bar links
• Brakes: Full replacement stainless brake lines (front & rear; set up for dual rear lines)
• Steering/Centering: HD adjustable track bar
• Rear Traction: Stage 2 gusseted traction bar kit
• Rear Height: Fabricated blocks (choose height) + U-bolts with top plates
• Shocks: Multiple valved-for-this-kit options (see below)

Choose Your Front Setup

• Short-Arm 4-Link: Maximum control over axle movement and wheel hop—great for hard launches, sled pulls, and high-torque use.
• Adjustable 3-Link: Tighter steering feel, excellent street manners, more articulation and shock absorption off-road; fully adjustable caster.

Rear Blocks & U-Bolts

• Blocks: Choose your block height to fine-tune stance (level, slight rake, or higher rear).
• U-Bolts: Available in 5/8" or 3/4" diameters (select SRW or DRW to match your truck).

Leaf Pack Type (How to Pick)

• Standard Leaf Pack: Top leaf runs eye-to-eye; typical stack is ~2–3" thick.
• Top-Mounted Overload: Thicker stack with a small spacer between the main pack and the top overload (not fixed at the ends). Choose this if your pack is thicker than ~3". 

Shock Options (Valved for This Application)

• Bilstein 5100: Great all-around ride and looks
• Bilstein 5160 (front resi): Step-up control; better seal orientation for harsh/salty climates
• Fox 2.0 IFP: Non-resi or front-resi packages for increased performance
• PMF-Tuned King 2.5 Resi: Ultimate on/off-road performance

Important Notes

• Front driveline: At ~3.5" lift, most trucks maintain acceptable front driveshaft angles for typical street/towing use. Aggressive off-road or high-angle use may warrant driveline upgrades—ask our team for guidance.

Who This Kit Is For

• Owners who want a true 3.5" lift with a comfortable daily ride
• Trucks that tow regularly and need rear stability
• Higher-horsepower builds that need to control wheel hop
