Rough Country Wheel Spacers for Chevy/GMC 1500 — 1.5" Pair Silver, 6x5.5 Bolt Pattern

Rough Country 1.5" aluminum wheel spacers push your wheels outward to accept wider tires and give Chevy/GMC 1500 trucks and SUVs a broader, more stable stance without changing suspension components.

These 1.5-inch wheel spacers are engineered to work with Chevy and GMC 1500-series trucks and SUVs that use a 6x5.5 (6x139.7mm) bolt pattern. Machined from 6061-T6 aluminum for strength and corrosion resistance, the spacers include preinstalled studs and come as a pair to shift wheel position outward by 1.5 inches. They are a simple bolt-on solution for drivers who want increased track width, an aggressive look, and improved handling when running wider tires.

How do these spacers help my truck handle wider tires?

By moving each wheel 1.5 inches away from the hub, these spacers create room for larger or wider tires without altering suspension geometry. The wider track reduces lateral load transfer in corners and can make steering feel more planted.

• 1.5" offset increase per wheel for additional clearance
• Better tire clearance at fenders and control arms
• More stable cornering due to increased track width
• Compatible with typical light-truck wheel dimensions

What are the construction and fitment specifics I should know?

Rough Country wheel spacers are CNC-machined from 6061-T6 aluminum, providing a balance of strength and corrosion resistance while keeping weight low. They are drilled for a 6x5.5 bolt pattern with a 3.08-inch center bore and M14x1.5 thread pitch.

• Material: 6061-T6 aluminum for durability and rust resistance
• Center bore: 3.08" to center on hub accurately
• Thread pitch: M14x1.5 with preinstalled studs for easy assembly
• Sold as a pair; designed for Chevy/GMC 1500 trucks and SUVs (1988–2021)

Do I need to modify anything during installation?

Installation is a straightforward bolt-on process using the included studs, but certain model years require a small trim to factory studs. Follow the vehicle-specific guidance to ensure correct stud engagement and wheel fitment.

• Includes (2) 1.5" spacers with preinstalled studs for quick fitment
• 1999 and newer Chevy/GMC models: factory studs must be trimmed by 0.25" before installing
• Torque lug nuts to the wheel manufacturer's specifications after installation
• Check wheel backspacing and caliper clearance before final assembly

What warranty and support come with these spacers?

• Rough Country Limited Lifetime warranty for manufacturing defects
• Technical fitment notes for 1988–2021 Chevy/GMC 1500 models included
• Customer support available for installation or compatibility questions

Who is this for: These Rough Country 1.5" wheel spacers are intended for Chevy and GMC 1500 truck and SUV owners who want to run wider tires, improve lateral stability, or achieve a more aggressive wheel stance without changing suspension parts. They suit DIY installers and professional shops alike, provided the installer follows the trim requirement for late-model factory studs and confirms wheel clearance and torque specifications.
