When you're looking to transform the stance and capability of your 2015–2020 Ford F-150, two popular options are a 4-inch suspension lift kit or a 2.5-inch leveling kit. Each offers unique benefits, challenges, and outcomes—so which one is right for your build?

What Is a 2.5-Inch Leveling Kit?

A 2.5-inch leveling kit raises the front of your truck to eliminate factory rake and gives you just enough lift to fit larger tires. This makes it a great choice for budget-conscious daily drivers who want a more aggressive look without modifying the rear suspension.

Pros of a 2.5" Leveling Kit:

• Affordable and easy to install
• Fits up to 33” tires
• Similar ride quality to stock
• Perfect for achieving a level stance

Cons:

• Minimal ground clearance increase
• Upper control arm contact on some builds at full droop
• Increased stress on front end components

This leveling kit from Auto Spring features CNC laser-cut steel spacers with an innovative 1/4" offset design that clears the upper control arm at full suspension travel—solving a common issue with other spacer kits.

What Is a 4-Inch Lift Kit?

A 4-inch lift kit raises the front and rear suspension, giving your F-150 a commanding presence and increased ground clearance. It’s perfect for those who want to run 35” tires, explore rugged terrain, or simply turn heads.

Pros of a 4" Lift Kit:

• Solid improvement in ground clearance
• Clears 35x12.50" tires
• Significantly more aggressive appearance

Cons:

• Higher cost and install complexity
• Requires cutting and drilling
• May need aftermarket wheels
• Fuel economy may decrease slightly

Real Reviews from Stage 3 Customers:

"Rides great and looks even better"

Do I Need an Alignment After Installation?

YES—for both kits.

No matter the size of the lift, installing a leveling or suspension kit changes your alignment geometry. Without a proper post-install alignment, expect:

• Uneven tire wear
• Reduced steering response
• Reduced ride comfort

Always have a professional alignment done immediately after installation.

What About Wheel Fitment?

Stock Wheels & Leveling Kits:

You can run your stock wheels with up to 33" tires using a 2.5” leveling kit like the Auto Spring. Some customers have fit up to 35s with no rub, depending on tire width and offset.

Stock Wheels & 4" Lift Kits:

Stock wheels don’t typically work with most 4” kits—including the Rough Country 55530. The lifted knuckles and repositioned components require:

• At least 18" wheels
• 4.5” of backspacing
• Offset of 0mm to -12mm

Stock 18" wheels are limited to an 11" wide tire due to clearance issues
