ATV Wheel Spacers 12x1.5 Studs 1.5in 4 Lug Spacer Adapters - Improved

In this review the focus is on a set of 1.5 in ATV wheel spacers that aim to increase tire clearance and give a wider stance to compatible Polaris models. The reviewer found these spacers useful for owners who need a reliable way to fit wider or higher-traction tires or to create extra room for chains and accessories. Fitment is the single biggest reason to buy: they are designed specifically for 4/110 bolt pattern wheels with M12x1.5 studs and a center bore not larger than 74mm, so when they match your machine they solve clearance and stance issues cleanly.

Key Features

• Fitment: Designed for 4/110 bolt pattern and M12x1.5 studs, these spacers ensure correct alignment on compatible Polaris Ranger and RZR models.
• Thickness: At 38mm (1.5 in) thickness they provide measurable increase in track width and tire clearance for wider tires or chains.
• Material: CNC machined from 6061-T6 aluminum billet for a strong but lightweight spacer that resists flex under load.
• Hardware: Pre-installed 10.9 grade bolts provide higher strength fasteners out of the box and simplify installation.
• Finish: Anodized surface adds corrosion resistance so the silver finish does not rust or fade quickly in outdoor use.
• Compatibility note: Intended only for wheels with a hub bore up to 74mm and not for 3/8-24 or 12x1.25 studs, which avoids misuse.

Who It's For

This product is best for owners of Polaris 2013+ Ranger, 2014+ RZR XP 1000, 2015+ RZR S 900 and 2015+ RZR Trail 900 models with 4/110 bolt pattern and M12x1.5 studs who want extra clearance or a wider stance. It is also suited to riders who fit larger tires or need room to run front tire chains without rubbing.

It is not for vehicles with a hub bore larger than 74mm, wheels using 3/8-24 or 12x1.25 studs, or those that have different bolt patterns. Buyers unsure about fitment should verify wheel stud thread pitch and hub bore before purchase or contact the seller for clarification.

Pros & Cons

Cons
