ezaccessory 4 Wheel Adapters: 4×156 to 5×4.5

These adapters convert a 4x156mm bolt pattern to 5×4.5″ (5×114.3mm) bolt pattern. They are constructed from aircraft-quality TRUE forged 6061-T6 billet aluminum and CNC-machined for precision. The set uses heat-treated 12×1.5 studs and includes lug nuts. Anodized coating offers corrosion resistance and a robust load-bearing design suitable for off-road use. The manufacturer notes compatibility with Polaris RZR Turbo R or Pro R wheels, among others, but vehicle fit should be validated with a garage check to ensure wheel compatibility beyond the listed examples.
ECCPP 4×4.5 to 5×4.5, 1 Inch Adapters

ECCPP presents a 1-inch thickness wheel adapter kit, converting 4×4.5 to 5×4.5. The package includes two adapters with thread locker glue. The listing specifies a range of fitment guidance, including hub bore and torque recommendations (75-85 ft-lbs). It emphasizes verifying bolt count, circle diameter, and bore size prior to ordering, and notes that this product changes the bolt pattern rather than functioning as a spacer. The design aims to improve handling and stability at speed while providing an aggressive look.
SuperATV Polaris Adaptor: 4/156 to 5/114.3

SuperATV’s billet-aluminum adapters convert 4/156 bolt patterns to 5/114.3, with a 1.5-inch thickness and isc pre-installed wheel studs.

Buying Guide
- Bolt pattern compatibility: Ensure the adapter converts the exact vehicle bolt pattern to the wheel bolt pattern you intend to use. Common conversions in this set are 4×4.5 to 5×4.5 and 4×156 to 5×4.5.
- Thickness and clearance: Adapter thickness affects wheel offset and clearance with suspension, calipers, and fenders. Thicker adapters (1.5″ or more) may improve stability but could require longer lug nuts or careful fit checks.
- Center bore and hub-centric design: A hub-centric adapter reduces vibration and mounting stress. Check the hub bore size (e.g., 73.1mm) and whether the adapter is hub-centric for your vehicle.
- Material and construction: Billet aluminum and forged aluminum offer high strength-to-weight ratios and corrosion resistance. Steel options are typically more budget-friendly but heavier.
- Studs and lug nuts: Verify whether adapters include studs and nuts, and ensure thread pitch (commonly 12×1.5) matches your wheels and hub.
- Torque specifications: Follow the recommended torque (often around 70–85 ft-lbs) to ensure safe installation and to prevent stud or lug failures.
- Installation considerations: Some entries require garage verification (Amazon-confirmed fit) to ensure compatibility with your exact vehicle, wheel size, and rim type.
- Warranty and safety: Look for corrosion resistance (anodized finishes) and manufacturer-provided safety notes. Consider adapters that provide clear installation instructions and support.
- Intended use: Off-road driving, towing, or high-speed highway use may demand different thicknesses or materials. Balance clearance, weight, and load capacity for the intended application.
