Camshaft Kit, Chain Drive, Twin Cam, Part 330-0328","description":"Camshaft Kit - 635 H.O. - Chain Drive - Twin Cam\n\u003cp\u003eThe S\u0026amp;S Cycle 635 H.O. Camshaft Kit is designed for modified Harley-Davidson Twin Cam engines requiring a high-lift camshaft and strong midrange-to-top-end performance. It is intended for large-displacement engines with compression ratios from 10.0:1 to 11.0:1, making it a suitable choice for performance builds that demand increased valve lift and optimized power delivery. The chain-drive design supports reliable operation in compatible Twin Cam applications.\u003cbr\u003eThis camshaft kit can be used with stock, unported cylinder heads, although S\u0026amp;S Cycle CNC-ported heads are recommended to help maximize the performance potential of the camshaft profile. The strongest power gains are targeted across an operating range of approximately 3,000 to 6,000 rpm, making this kit well suited to riders and builders seeking enhanced acceleration and higher engine output. This is not a bolt-in camshaft kit and requires careful installation and engine-component verification by a qualified technician.\u003cbr\u003eEach kit includes the camshafts, cam bearings, gear cover gasket, retaining ring, O-ring, thread-locking compound, and installation instructions. During installation, the installer must verify coil-bind clearance, valve-to-valve clearance, and valve-to-piston clearance to ensure proper operation and prevent engine damage. Manufactured in the USA, the S\u0026amp;S Cycle 635 H.O. camshaft kit combines application-specific performance design with the components needed for a professional installation. Confirm engine configuration, compression ratio, cylinder-head setup, and required clearances before ordering.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eApplication: Designed for modified Twin Cam engines with large displacement and compression ratios between 10.0:1 and 11.0:1\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePerformance: High-lift camshaft profile delivers its strongest power from approximately 3,000 to 6,000 rpm\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCylinder Heads: Compatible with stock, unported heads, with S\u0026amp;S Cycle CNC-ported heads recommended for maximum performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInstallation: Not a bolt-in camshaft kit; professional installation and clearance verification are required\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eClearance Checks: Installer must check coil bind, valve-to-valve clearance, and valve-to-piston clearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncluded Components: Camshafts, bearings, gear cover gasket, retaining ring, O-ring, thread-locking compound, and instructions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eManufacturing: Made in the USA\u003c\/li\u003e\u003c\/ul\u003e","brand":"S\u0026S CYCLE","offers":[{"title":"Default Title","offer_id":50542156513473,"sku":"0925-0836","price":418.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0060\/5929\/4802\/files\/12769.png?v=1787979377","url":"https:\/\/teamdreamrides.com\/products\/s-s-cycle-635-h-o-camshaft-kit-chain-drive-twin-cam-part-330-0328","provider":"Team Dream Rides","version":"1.0","type":"link"}
