Engineered to withstand the extreme lateral loads of competitive racing, this spacer (measuring an actual 5mm in width) provides a rock-solid mating surface between your wheel hub and spindle. It eliminates the vague handling and wheel deflection that plague inferior setups, allowing you to attack high-speed apexes with absolute confidence.\u003c\/p\u003e\u003ch2\u003ePrecision Tuning Beyond the Engine Carburettor\u003c\/h2\u003e\u003cp\u003eA winning chassis setup demands the same meticulous attention to detail as tuning your \u003cem\u003eengine carburettor\u003c\/em\u003e or installing comprehensive \u003cem\u003eengine rebuilding kits\u003c\/em\u003e. Every millimeter of track width directly impacts your kart's scrub radius, jacking effect, and overall grip levels. By utilizing this 17mm ID metric spacer, racers can execute micro-adjustments to the front track, shifting the weight transfer characteristics to cure mid-corner understeer or stabilize corner-entry oversteer. Constructed from high-density, crush-resistant materials, it guarantees that your wheel fitment remains perfectly square, lap after grueling lap.\u003c\/p\u003e\u003ch2\u003eDurability That Matches Your Brake Calliper Parts\u003c\/h2\u003e\u003cp\u003eJust as you rely on premium \u003cem\u003ebrake calliper parts\u003c\/em\u003e to haul your chassis down from top speed, your wheel spacers must endure immense compressive forces without deforming. This 4mm\/5mm metric spacer is machined to exacting tolerances, ensuring a seamless slide over 17mm international stub axles. Whether you are fine-tuning a high-horsepower shifter kart or maximizing the momentum of a spec class setup running a fresh \u003cem\u003elo206 carburetor kit\u003c\/em\u003e, this spacer maintains structural integrity under heavy braking and aggressive curb strikes. It simplifies pit lane adjustments, allowing mechanics to rapidly swap widths during frantic practice sessions.\u003c\/p\u003e\u003ch2\u003eCore Technical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExact 17mm Inner Diameter:\u003c\/strong\u003e Slides flawlessly over standard international kart stub axles without binding or excessive play.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Track Width Control:\u003c\/strong\u003e Listed as a 4mm spacer with an actual 5mm width, ideal for granular front-end geometry adjustments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrush-Resistant Construction:\u003c\/strong\u003e Engineered to withstand extreme compressive loads from wheel nuts without deforming or cracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Contact Patch:\u003c\/strong\u003e Facilitates precise scrub radius tuning to maximize tire grip and reduce rolling resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Class Compatibility:\u003c\/strong\u003e Fully legal and highly effective across all sprint, enduro, and oval karting divisions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid Pit Lane Swaps:\u003c\/strong\u003e Smooth internal bore allows for lightning-fast track width changes during critical tuning windows.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVibration Dampening:\u003c\/strong\u003e High-quality material composition helps isolate the hub from minor spindle vibrations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is this listed as a 4mm spacer if it measures 5mm?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e While commonly referred to as a 4mm spacer in karting terminology, the actual physical width is 5mm. This is a standard industry naming convention, but please account for the 5mm measurement when calculating your total front-end track width.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this spacer compatible with all kart stub axles?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, this spacer features a 17mm inner diameter, which is the standard size for international karting stub axles. It is designed to slide on easily without binding.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I use these spacers to tune my kart's handling?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e You can use these spacers to adjust your front track width. Increasing the track width generally increases front-end grip and can help reduce mid-corner understeer, while decreasing the width can help stabilize the kart if it feels too aggressive or \"darty\" on corner entry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to replace these spacers frequently?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e These are constructed from high-density, crush-resistant material designed to withstand extreme lateral loads. However, you should inspect them periodically for signs of cracking or deformation, especially after heavy curb strikes or if you notice your wheel fitment is no longer square.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I stack multiple spacers on one side?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, you can stack spacers to achieve your desired track width. Ensure that you have enough thread engagement on your stub axle to safely secure the wheel nut after adding additional spacers.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Products From Vendor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/k711n-ridolfi-righetti-40mm-rear-hub-115mm-length-black-k711n\"\u003eRighetti Ridolfi K711N 40mm Rear Wheel Hub - 115mm Length Black - Shifter \u0026amp; 206 Karts\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/30mm-sprocket-hub-black-sc30-bk\"\u003eRighetti Ridolfi SC30-BK 30mm Sprocket Hub - Black Anodized - CIK\/FIA Legal\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/40mm-soft-axle-40mmaxs\"\u003eRighetti Ridolfi KD120-S6 40mm Soft Rear Axle - 3mm Wall - Margay Ignite\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SwiftKarting","offers":[{"title":"Default Title","offer_id":48158138401027,"sku":"WS4MM","price":1.46,"currency_code":"USD","in_stock":true}],"url":"https:\/\/phishstonesproducts.myshopify.com\/products\/righetti-ridolfi-metric-front-wheel-spacer-17mm-id-x-4mm-all-classes","provider":"PhishStones Products","version":"1.0","type":"link"}
