The single biggest reason to buy is straightforward: these spacers are CNC machined from 6061-T6 aluminum and come pre-installed with high strength 12.9 grade bolts, delivering a lightweight yet robust spacer that fits the specified 4\/156 bolt pattern and a 131mm center bore. For riders on Polaris and Kawasaki models listed in the fitment, they provide a reliable way to run wider or larger tires without complex modifications.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCNC machined construction:\u003c\/strong\u003e The 6061-T6 aluminum build keeps weight low while providing durable support for heavier tires and wider track setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-installed high grade bolts:\u003c\/strong\u003e The included 12.9 grade bolts reduce installation steps and improve long term clamping strength for safer wheel mounting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnodized finish:\u003c\/strong\u003e The black anodized surface adds corrosion resistance so the spacers resist rust and fading in wet or muddy conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise fitment:\u003c\/strong\u003e Designed for a 4156 to 4156 bolt pattern and 131mm center bore, these spacers fit specific Kawasaki and Polaris model years without hub grinding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25mm thickness:\u003c\/strong\u003e The 1 in spacer thickness gives noticeable additional clearance for wider tires or chains while maintaining handling balance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThese spacers suit ATV owners who ride Polaris Rangers, RZR, Sportsman series or the listed Kawasaki quads and who want a bolt-on way to increase tire clearance or achieve a wider stance.

Also, if a vehicle requires a different bolt pattern than 4156mm, these spacers will not work.\u003c\/p\u003e\u003ch2\u003ePros \u0026amp; Cons\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSolid build from 6061-T6 aluminum for good strength-to-weight performance.\u003c\/li\u003e\n\u003cli\u003ePre-installed 12.9 bolts simplify installation and improve durability.\u003c\/li\u003e\n\u003cli\u003eBlack anodized finish resists corrosion and keeps appearance consistent.\u003c\/li\u003e\n\u003cli\u003eCompatible with many Polaris and Kawasaki model years, offering broad fitment where specified.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCons\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOnly compatible with wheels using 3\/8-24 studs and a center bore up to 131mm, so fitment is limited.\u003c\/li\u003e\n\u003cli\u003eAvailable only in a single thickness (25mm) which may not suit every desired clearance or stance preference.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBolt Pattern\u003c\/td\u003e\n\u003ctd\u003e4156 to 4156\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter Bore\u003c\/td\u003e\n\u003ctd\u003e131mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThickness\u003c\/td\u003e\n\u003ctd\u003e25mm (1 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Pitch\u003c\/td\u003e\n\u003ctd\u003e3\/8-24\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e4 pcs 4 lug wheel spacer adapters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e6061-T6 aluminum billet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlack anodized\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eOur Verdict\u003c\/h2\u003e\u003cp\u003eThe GAsupply 4156 25mm wheel spacers are a practical, well-made option for owners of compatible Polaris and Kawasaki ATVs who want extra tire clearance or a wider stance without heavy modification.
