Suspension Strut Spacer

What Are Suspension Strut Spacers?

A suspension strut spacer is a precision-machined component that installs above or below your vehicle's existing strut assembly, effectively increasing ride height without requiring a full suspension overhaul. Rather than replacing your factory struts or coil springs, a strut spacer works with what you already have, making it one of the most straightforward ways to level a truck or SUV and gain a modest lift.

In practice, strut spacers are most commonly used as part of a leveling kit — correcting the front-to-rear rake that most factory trucks are built with to accommodate payload. By adding a spacer at the front strut mount, owners can bring the front of the vehicle up to match the rear stance, creating a cleaner, more level look and opening up clearance for larger tires and wheels.

How Strut Spacers Work

Strut spacers typically mount at the top of the strut tower — between the strut assembly and the vehicle's chassis — effectively lowering the strut's mounting point and raising the vehicle's ride height. Quality spacers are commonly manufactured from CNC-machined billet aluminum or heavy-gauge steel, both of which offer the structural integrity needed to handle road and trail stress over time.

One of the key practical advantages of a strut spacer is installation simplicity. Because the spacer goes on top of the existing strut assembly, there's no need to disassemble the strut or use a coil spring compressor. This makes strut spacers one of the more DIY-friendly suspension modifications available to truck and SUV enthusiasts. Typical lift ranges run from about 1 inch to 3 inches, though the actual lift at the wheel can vary based on the suspension geometry of a specific vehicle.

What to Consider Before Buying

• Lift height: Strut spacers are generally best suited for modest lifts. For larger lifts, a full suspension kit may be more appropriate to maintain proper CV joint angles and steering geometry.
• Material: Billet aluminum spacers are lightweight and corrosion-resistant; steel options offer maximum strength for heavier-duty applications.
• Vehicle compatibility: Always verify that a spacer is designed specifically for your year, make, and model — fitment matters for both safety and alignment.
• Post-install alignment: A professional wheel alignment is strongly recommended after any ride-height change to ensure proper tire wear and handling.
• Existing strut condition: Strut spacers work best on vehicles with struts that are in good condition. Installing a spacer on worn struts can accelerate component wear.
