Richeer 1.5in 6x5.5 Wheel Spacers Kit — Billet Aluminum, 108mm Hub-Centric, Grade 12.9 Studs

These spacers are a set of four billet-aluminum adapters designed to move each wheel outward by 1.5 inches (38.1 mm). Built with CNC machining, anodized finishes and Grade 12.9 studs, they pair modern manufacturing with high-strength hardware to fit a long list of full-size trucks and SUVs. Use them to correct offset, create a wider stance for a more aggressive look, or gain a small handling advantage when fitment and vehicle clearance are properly considered.

Which vehicles will accept these spacers?

The Richeer 6x5.5 (6x139.7) spacers have a 108 mm hub bore and are intended for many GM full-size platforms plus select Ram models. They are sold as a four-piece kit with 14×1.5 stud threads and vehicle-specific fitment should be checked before purchase.

• Compatible models include Silverado and Sierra 1500 (1999–2023), Tahoe (1995–2023 variants), Suburban and Yukon XL ranges, Avalanche, Express, Savana, Escalade, and select Ram 1500 years.
• Designed for 6-lug applications — confirm your wheel bolt pattern matches 6x5.5" (6x139.7).
• Hub-centric 108 mm bore helps center the wheel on the hub for proper load transfer.

How are these spacers made and how durable are they?

Richeer manufactures these spacers from forged 6061-T6 billet aluminum with CNC precision, then applies an anodized surface to resist corrosion and wear. They use Grade 12.9 studs, which provide significantly higher tensile and yield strength compared with lower-grade fasteners.

• 6061-T6 billet forging provides a strong, fatigue-resistant base material.
• CNC machining ensures accurate bolt patterns, hub bore sizing, and flat mounting faces.
• Grade 12.9 studs rated to roughly 1000 MPa tensile strength for improved joint security.

What handling and fitment benefits can I expect after installation?

Moving the wheel outboard by 1.5" widens the track, which can deliver a more planted appearance and slight improvements in lateral stability and anti-roll characteristics. Results depend on tire size, suspension setup and alignment; spacers are primarily an aesthetic and clearance solution rather than a performance retrofit.

• Gives a wider, more aggressive stance and clears larger brake components or suspension parts.
• Can improve perceived handling by increasing track width and reducing body roll marginally.
• Helps fit aftermarket wheels with negative offset without rubbing the fender or inner components.

How should I install and maintain these wheel spacers?

Installation requires correct torque procedures, using the supplied hardware and following vehicle manufacturer torque specs for studs and lug nuts. Periodic re-check of torque and inspection for corrosion or damage will help ensure long-term safety and performance.

• Mount each spacer flush to the hub; use hub-centric alignment before torquing to spec.
• Tighten hardware in a star pattern and re-torque after the first 50–100 miles.
• Inspect studs, nuts and anodized surfaces regularly for wear, corrosion, or loosening.

Who is this for: Richeer 1.5" 6x5.5 wheel spacers suit truck and SUV owners who need improved wheel clearance, a wider stance, or proper fitment for aftermarket wheels. They are aimed at DIY installers and professional shops alike who prioritize precision machining, high-strength studs, and hub-centric design on GM full-size platforms and compatible Ram 1500 years. Verify your vehicle’s bolt pattern, wheel offset, and brake clearance before ordering to ensure correct fitment and safe use.
