Dynofit 6×5.5 to 6×5.5 Wheel Spacers – 4Pcs
The Dynofit set converts 6×139.7mm bolt patterns to a firm 6×139.7 setup with a 108mm hub bore and two-inch thick spacers. Manufactured by forged 6061-T6 aluminum, these spacers emphasize strength-to-weight efficiency and corrosion resistance. The included M14x1.5 studs are designed to resist rust and wear, and CNC processing ensures precise fitment. This option is suitable for a broad range of GM trucks and SUVs, including Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon, and Escalade models, as well as Ram 1500 variants. When installing, verify that the vehicle’s hub and wheel studs align with the 108mm bore and 6×5.5 bolt pattern for optimal balance and safety. The spacer’s dual-purpose design makes it appropriate for both street driving and off-road conditions, provided proper torque specifications are observed.
KSP 4PCS 6×139.7 Wheel Spacers For Toyota/Tacoma/Tundra
These 6×139.7 spacers are forged from 6061-T6 aluminum to deliver added stiffness and resilience under load. They’re designed for 2023+ Tundra, 2025+ Tacoma, and other Toyota-Lexus models, with a hub bore of 95.2mm and a thickness of 1.5 inches. The kit includes heat-treated, 10.9-grade bolts and a thread locker for secure fastening. The manufacturer notes careful measurement of OEM hub dimensions to minimize vibration, and emphasizes compatibility with non-locking lug patterns. This option works well for widening stance on select Toyota trucks while maintaining reliable alignment and load distribution when used with the recommended torque range of 85–95 ft-lbs.
KSP 6×135 To 6×135 Wheel Spacers For F150
Designed for Ford’s 6×135 pattern, this KSP kit converts F-Series bolt patterns with 1.5-inch thickness and an 87.1mm hub bore. It includes M14x1.5 studs and is built from forged 6061-T6 aluminum with 10.9-grade bolts, which provides strength without excessive weight. The package targets 2015–2025 F150, Expedition, and Navigator models, and comes with a recommended torque range of 85–95 ft-lbs. It’s important to confirm the vehicle’s wheel stud configuration and hub dimensions before purchasing, especially if your truck has locking hubs or aftermarket components that could affect fitment.
KSP 6X5.5 Tacoma/4Runner Wheel Spacers
This set provides 1.5″ spacers for Toyota’s 6×5.5″ pattern (6×139.7mm) with 108mm hub bore. It is marketed as non-hubcentric, which means it relies on proper wheel centering through bolts and lug nuts rather than a built-in hub centering lip. The hardware uses M12x1.5 studs, and the kit includes thread locker for secure fastening. It’s suitable for a wide array of 4Runner, Tacoma, and Tundra configurations, including variants that lack locking hubs. Users should verify the vehicle-specific compatibility and ensure the OEM wheel studs are long enough to accommodate the spacers and extended nuts, especially on lifted or modified suspensions.
KSP 6X5.5 Spacers For Silverado/Sierra/Tahoe/Yukon
These spacers adapt 6×139.7mm bolt patterns with a 78.1mm hub bore, 1.5″ thickness, and M14x1.5 studs. Manufactured with forged 6061-T6 aluminum, the spacers are designed for heavy-duty performance on Silverado 1500, Tahoe, Suburban, Yukon, Sierra, and Escalade models. The product emphasizes corrosion resistance and precise machining to ensure a snug fit with minimal vibration. The included high-grade bolts and thread locker help secure the spacers during operation, while the non-hub-centric design requires careful torque and alignment to maintain stability at speed and during off-road use.
Buying Guide: Key Purchase Considerations
- Vehicle compatibility: Match bolt pattern (PCD), hub bore, and wheel stud configuration. Incompatible spacers can cause vibrations, improper seating, or safety risks.
- Material and construction: Forged aluminum (6061-T6) spacers offer greater strength and durability than cast alternatives. Look for corrosion-resistant finishes such as black anodizing.
- Thickness and stance goals: Decide how much width you want to add. Heavier spacers may affect steering feel and brake clearance; consider total wheel offset and fender clearance.
- Hub-centric vs non-hub-centric: Hub-centric spacers improve balance by centering on the hub. Non-hub-centric spacers rely on lug nuts for alignment and may require exact fitment to avoid vibrations.
- Hardware quality: Durable studs and high-grade bolts (ISO/DIN 10.9) reduce the risk of stripping or loosening under load. Ensure thread locker is included and properly applied during installation.
- Torque specifications: Follow manufacturer torque ranges to secure spacers without over-tightening, which can damage studs or wheels.
- Warranty and testing: Look for products that have SGS or similar testing and clear warranty coverage for safety-critical components.
- Installation considerations: Some models require extended or ET-style lug nuts, especially when using extended spacers or lifted suspensions. Verify nut compatibility before purchasing.
- Legal and liability aspects: Ensure the spacers comply with local regulations and won’t interfere with safety systems or warranties.
When selecting wheel spacers or adapters, prioritize compatibility with your vehicle’s specific year, trim, and wheel package. Consider consulting a professional installer if you’re uncertain about bolt-length requirements, hub bore tolerances, or potential interference with brake calipers and suspension components. With careful selection and proper installation, wheel spacers can widen your track, improve braking clearance, and accommodate broader wheel choices without compromising safety.
