Aeagle 4x110 to 4x137 Wheel Adapters 1" Forged 6061-T6 Aluminium 4-Lug Spacers with M10x1.25 Studs (4-Pack)

Aeagle 4X110 to 4x137 1" wheel adapters are forged 6061-T6 aluminum 4-lug spacers that convert a 4x110 bolt pattern to 4x137 while maintaining a 77.8mm hub bore and using M10x1.25 studs.

These wheel adapters let owners of many Honda, Yamaha and Suzuki ATVs and UTVs fit alternate wheels safely and accurately. CNC-machined from forged 6061-T6 aluminum and supplied with grade 10.9 heat-treated studs, the four-piece set is engineered for precision fitment, consistent wheel offset, and reliable lateral strength. The kit includes four 1" (25.4mm) thick adapters designed to match popular OEM hubs and broaden wheel options without altering original suspension geometry.

Which vehicle models will these adapters fit?

These adapters are designed for a variety of Honda, Yamaha and Suzuki ATVs with a factory 4x110 bolt pattern. Always verify model year and hub measurements before purchase to ensure correct fitment.

• Honda: Recon 250 (1997–2009), FourTrax 300 (1988–2000), Rancher 350 (2000–2009), Rancher 400 (2004–2009), Foreman series (1996–2006, 1998–2004, 2005–2016), Rancher 420 (2004–2016), Rincon 650/680 (2003–2016).
• Yamaha: Bear Tracker, Big Bear series, Bruin 250/350, Wolverine 350X/450FX, Grizzly 350/450/550/700 (various 1987–2016 models).
• Suzuki: Eiger 400 (2002–2007), Ozark 250 (2002–2009), King Quad 400/450 (2001–2016).
• Measure hub bore 77.8mm and confirm bolt pattern conversion 4x110 to 4x137 before installation.

How are these adapters made and what materials are used?

The adapters are produced by CNC machining from forged 6061-T6 aluminum for a high strength-to-weight ratio and consistent dimensional accuracy. Threaded studs are grade 10.9 heat-treated bolts, chosen for improved tensile and shear resistance compared with lower-grade hardware.

• Material: forged 6061-T6 aluminum (CNC machined).
• Studs: M10x1.25, grade 10.9 heat-treated bolts.
• Thickness: 1" (25.4mm) to adjust track width without major suspension changes.
• Hub bore: 77.8mm to match many OEM hubs for centered fitment.

What installation and safety steps should I follow?

Proper installation is crucial for secure operation. Clean mating surfaces, inspect hubs and brake components for damage, and torque the hardware to the recommended value to avoid loosening or uneven stress.

• Clean hub and adapter surfaces to remove rust and debris before fitting.
• Check brake discs and hub for cracks or damage; do not install if compromised.
• Tighten wheel bolts to 110–150 N·m as specified; use correct torque sequence.
• Do not use these adapters for towing and verify non-OEM wheels match specifications.

Will these adapters change handling or wheel clearance?

A 1" spacer increases track width slightly, which can alter scrub radius and wheel clearance; effects are usually subtle but vary by vehicle and wheel choice. Confirm tire, wheel and fender clearance to prevent rubbing during suspension travel and steering lock.

• Offset change: +25.4mm per wheel (1" thickness) affects stance and clearance.
• Check turning and suspension travel for tire or fender contact.
• Non-original wheels should be verified for correct offset and load rating.

Who is this for: These Aeagle adapters are intended for ATV/UTV owners, mechanics and aftermarket modifiers who need a reliable, precision-made solution to adapt 4x110 hubs to 4x137 wheels on compatible Honda, Yamaha and Suzuki models. Choose this kit if you require CNC accuracy, a centered 77.8mm hub fit, and high-strength studs for everyday off-road use—while following recommended installation and safety checks.
