2 Inch Wheel Spacers For CAN-AM And More
The FLYCLE spacers provide a solid 2-inch thickness suitable for widening stance on machines with a 4×137 bolt pattern. They feature a 110 mm hub bore and 10×1.25 thread pitch, aligning with common hub designs on CAN-AM Defender, Outlander, Commander, and Kawasaki Mule models. The package includes four spacers, as well as two high-strength threadlockers and two user manuals to ease installation. Torque guidance suggests eight turns achieving roughly 85-90 LBS for secure mounting. While designed for several Can-Am and related platforms, users should verify precise fitment against their vehicle’s hub and wheel specs to avoid interference with drive components.
Key features at a glance include compatibility with 4×137 vehicles, accurate hub bore, and included installation aids. The spacers’ build aims to balance strength with a lower profile, helping maintain steering input and avoiding caliper contact on many setups. Potential users should confirm that their wheels and studs align with the 10×1.25 thread pitch, and note that some CAN-AM Maverick X3 variants may require different spacers or adapters.
ezaccessory 4×156 To 4×137 Wheel Adapters
The ezaccessory adapters convert a 4×156 bolt pattern to 4×137, enabling use of 4×137 wheels on machines that originally require 4×156. They are described as forged 6061 T6 billet, CNC-machined for precision, with high load capacity and corrosion resistance due to anodizing. The package includes 1-inch thick adapters and mounting hardware, including studs or nuts as specified. Designed for Polaris Outlaw and Can-Am Commander families among others, this solution can widen compatibility without changing the vehicle’s hub assembly. Always verify your vehicle’s year and model against the listed specs to ensure a proper match with the 110 mm hub bore and 12×1.5 thread pitch.
Considerations include ensuring the aftermarket wheels have correct center bore alignment, maintaining proper offset, and accounting for any impact on stability or suspension geometry when converting bolt patterns. This solution emphasizes durability and precision engineering while serving as a flexible option for mixed wheel sets.
Rough Country 1.5″ Wheel Spacers
Rough Country offers 1.5-inch spacers designed for 4×137 bolt patterns. These spacers come with preinstalled studs for convenience and are compatible with 4×137 mm wheels. They aim to widen tire stance and improve traction in off-road environments while preserving wheel alignment and hub engagement. The product emphasizes straightforward installation and a robust mounting system. Ideal for drivers seeking a simple upgrade to accommodate larger tires or improve stance without a full wheel conversion. As with any spacer, check clearance against brakes, fender arches, and suspension travel to avoid rubbing at full steering lock or suspension travel.
RockTrix RT104 14-Inch ATV Wheels Set
RockTrix RT104 wheels are 14×7, designed for 4×137 bolt patterns with a 4+3 offset. The package includes four wheels and 10×1.25 spline lug nuts, compatible with Can-Am Commander, Defender, Maverick, Outlander, and related models. The hub bore must be 110 mm or smaller, with a listed load rating per wheel. Buyers should verify fitment by cross-checking bolt pattern, center bore, and offset against their machine, and note that wheel caps are included while valve stems and lug nuts may be separate. The set provides a sturdy, stylish upgrade for enthusiasts seeking a broader footprint and improved traction on rough terrain.
Raceline A95SG Trophy 15×7 Wheels
The Raceline A95SG Trophy wheels are 15×7 with a 4×137 bolt pattern and a 10 mm offset, designed for rugged off-road use. They feature heavy-duty A356 aluminum construction with a beadlock-appearance and stainless steel bolts for a rugged, high-strength aesthetic. Available in satin black and stealth grey, these wheels are offered in multiple diameters to fit a variety of UTV configurations. The design emphasizes durability for aggressive trail riding, with attention to load distribution and tire stability. As with any upgrade, verify that the hub bore and stud size match your machine’s specifications to ensure a secure fit and reliable performance on demanding terrain.
Buying Guide: Key Purchase Considerations For 4×137 Wheels And Spacers
- Bolt pattern and hub bore compatibility: Confirm 4×137 bolt pattern and hub bore size (often 110 mm) to ensure proper fit with your vehicle and wheel choice.
- Wheel width and offset: Offsets like -4 to +0 or +4, and widths such as 14×7 or 15×7 affect track width, stability, and clearance against suspension, fenders, and brakes.
- Spacer vs. adapter vs. proper wheel: Spacers widen stance but do not change bolt pattern; adapters convert bolt patterns but add more rotating mass and potential load considerations. Choose based on intended use and load expectations.
- Material and build quality: Forged 6061 T6 billets, anodized finishes, and reinforced studs enhance durability, corrosion resistance, and longevity in off-road conditions.
- Center bore and lug measurements: Ensure the center bore matches or is larger than the hub bore; verify lug nut size and thread pitch (commonly 10×1.25) for secure mounting.
- Installation considerations: Check for clearance with brakes, calipers, sway bars, and fender clearance at full steering lock. Preinstalled studs and included hardware can simplify installation but verify torque specs from manufacturers.
- Impact on handling and warranty: Wider stance can improve traction but may alter steering response and ride characteristics. Confirm compatibility with vehicle warranty and recommended tire sizes with your manufacturer’s guidelines.
- Model-specific fitment: Some adapters and wheels are model-specific or year-specific. Always cross-check your exact vehicle year, model, and trim against the product description.
- Cost vs. value: High-quality forged components and genuine wheel sets offer durability but compare against spacer-based solutions for your intended use, especially if you switch between multiple vehicles.
