Our ball-bearing design replaces that sliding motion with rolling contact, which dramatically reduces friction.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eIn addition to the friction-reducing advantages of the bearing barrels, these components are made from specially treated Ti-6Al-4V Grade 5 titanium alloy. This material delivers exceptional strength while significantly reducing rotational inertia. The result is faster acceleration and efficiency, giving stock racers a competitive edge.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eR1B \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWeighing in at just 5.76g for the pair, these bones are 40.40% lighter than the standard bones and barrels.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli class=\"MsoNoSpacing\"\u003eServiceable and rebuildable\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIn-house ultra-high precision tight tolerance swiss machining\u003c\/li\u003e\n\u003cli\u003eMade from treated Ti 6Al-4V grade 5 Titanium alloy\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eImproved acceleration\u003c\/li\u003e\n\u003cli\u003eBetter braking response \u003c\/li\u003e\n\u003cli\u003eIncreased power transfer \u003c\/li\u003e\n\u003cli\u003eBetter agility and responsiveness when cornering\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLower overall vehicle weight\u003c\/li\u003e\n\u003cli\u003eLaser-etched logos and identification markings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIncludes:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ex2 R1B Titanium Bearing Barrel CVA Bones\u003c\/li\u003e\n\u003cli\u003ex2 Ball Bearing Barrel Axles\u003c\/li\u003e\n\u003cli\u003ex4 Ball Bearing, 3\/32\" × 3\/16\" × 1\/16\"\u003c\/li\u003e\n\u003cli\u003ex4 E-Clip, 1\/16\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eNote:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBearing barrels are not compatible with kit CVA shafts. \u003c\/li\u003e\n\u003cli\u003eR1B CVA bones are \u003cspan style=\"text-decoration: underline;\"\u003eonly\u003c\/span\u003e compatible with R1B differential outdrives.\u003c\/li\u003e\n\u003cli\u003eThese ultra-lightweight bones are optimized for stock racing, specifically for the 21.5 to 17.5 classes.
