Want a 6" lift that balances daily comfort, towing authority, and rear stability under high horsepower?

• Intended use: Daily driving comfort, confident towing, and solid control for high-HP builds

Why Choose the PMF Alpha 6" Lift Kit?

• Smooth ride + extra travel: Upgraded front dual-rate coil springs offer a comfy street ride and more than 3" of travel over stock. 
• Towing confidence: Retains OEM rear spring for payload capacity, plus adds a Stage 2 Gusseted Traction Bar for reduced axle wrap and wheel hop. 
• Adjustable stance: Multiple rear block heights let you dial in level, mild rake, or slight lift look.
• Shock options available: Choose shocks suited for looks, performance, or off-road endurance. 

What’s Included

• Front Coils: 4.5" ICON progressive-rate springs
• BMC Spacer: 1.5" body-mount cushion spacer
• Front Link System: Option of Long-Arm 4-Link or Adjustable 3-Link
• Sway Bar: 2.5" drop brackets & HD replacement links
• Brake Lines: Full-replacement stainless steel front & rear lines (dual-rear setup ready)
• Steering Alignment: HD drop track bar bracket with pitman arm + adjustable track bar
• Rear Traction: Stage 2 gusseted traction bar kit
• Rear Height: Fabricated blocks (choose height) + U-bolts w/ top plates
• Shocks: Multiple valved packages available (Bilstein 5100, 5160, Fox 2.0 IFP, PMF-tuned King 2.5). 

Choose Your Front Setup

• Long-Arm 4-Link: Maximizes axle control and wheel hop resistance—great for hard launches, tow, or sled pulls.
• Adjustable 3-Link Arms: Tighter steering feel, better street manners, improved articulation off-road, with caster adjustability. 

Rear Blocks & U-bolts

• Blocks: Choose the height that best matches your desired stance (level, slight rake, raised look).
• U-Bolts: Standard 5/8"; upgrade to 3/4" for high-HP/performance setups. Available for SRW or DRW. 

Leaf Pack Type (How to Pick)

• Standard Leaf Pack: Full-length top leaf from eyelet to eyelet, 2–3" thick. 
• Top-Mounted Overload: Thicker pack—includes spacer between main pack and overload (not fixed ends); select if pack > 3". 

Shock Options (Valved for This Application)

• Bilstein 5100: Great for daily driving and style
• Bilstein 5160 (front resi): Stepped-up performance, better seals for harsh or salty conditions
• Fox 2.0 IFP: Non-res / res options for more performance flexibility
• PMF-Tuned King 2.5 Resi: The top choice for on/off-road performance.

Important Notes

• Transfer Case Index Plate & Crossmember: 2017+ models have a front driveshaft sensitive to angles. Off-road or heavy 4x4 use demands the index plate/crossmember to maintain driveshaft angle. Moderate use may work without it, but risk of damage increases without. 

Who This Kit Is For

• Owners who want a true 6" lift with a comfortable daily ride
• Trucks that tow often and need rear stability
• High-horsepower builds looking to control wheel hop
