They combine forged 6061-T6 construction, CNC machining and high-grade studs to deliver improved stability and a cleaner fit when vehicle compatibility is confirmed. For drivers who require a 3.0in offset on the listed models, these spacers offer good function and cost efficiency, though buyers should check fitment and inspect units on arrival for consistent build quality.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWill these spacers fit my Corvette?\u003c\/strong\u003e\u003cbr\u003eThey fit Corvettes in the listed year range if your vehicle uses a 5x120.65 \/ 5x4.75 bolt pattern and a 70.5mm hub bore; always recheck vehicle compatibility before purchase.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo they cause vibration?\u003c\/strong\u003e\u003cbr\u003eWhen installed to the recommended torque, with mating surfaces cleaned and properly centered on the hub lip, vibration is typically avoided thanks to the hubcentric design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the bolts strong enough for highway use?\u003c\/strong\u003e\u003cbr\u003eYes, the preinstalled 10.9 grade studs are heat treated with high tensile strength designed to provide robust clamping for road use.\u003c\/p\u003e","brand":"ECCPP","offers":[{"title":"Default Title","offer_id":48204760547547,"sku":"B0186XW3BQ","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/1043\/1707\/files\/61ehKW_2AIL._AC_SL1500.jpg?v=1770226934","url":"https:\/\/gearmusthave.com\/products\/5x4-75-hubcentric-wheel-spacers-3in-5x120-65-to-5x4-75-centered-fit","provider":"GearMustHave","version":"1.0","type":"link"}
