Yes. Kami Speed is an authorized Exedy dealer sourced directly through Exedy Globalparts Corporation (Exedy USA). Every clutch kit, Hyper Single, twin-plate, and flywheel ships in original Exedy packaging with the Daikin winged logo, full warranty documentation, and the serial number intact. Exedy counterfeits are less common than with brands like HKS or MOMO, but gray-market parts and old stock can show up at suspiciously low prices on auction sites — typically missing warranty, often with incorrect specs, and never with manufacturer support if something goes wrong. Authorized purchasing keeps your warranty valid and your install backed by Exedy's tech support.

Most in-stock Exedy clutch kits and flywheels ship within 1 to 3 business days from US warehousing. Popular applications — K20, K24, B-series, SR20, EJ25, 4G63, 2JZ — are typically stocked. Less common applications, full Hyper Twin twin-plate setups, and made-to-order racing variants may have a 1 to 3 week lead time from Exedy USA. We confirm exact stock and ETA at order placement.

Exedy clutch kits and flywheels carry the standard Exedy manufacturer warranty against defects in materials and workmanship for unused, properly installed components. Returns on unused, uninstalled clutches and flywheels in original packaging are accepted within 30 days. Once a clutch has been installed or a flywheel has been mated to a crank, it is no longer returnable — this is standard across the clutch industry, since friction surfaces and contact patterns alter on first use. Defective products are handled through Exedy USA's warranty program, and Kami Speed processes RMA claims on your behalf.

Exedy Stage 1 Organic is a direct OEM-replacement upgrade — stock pedal feel, slightly increased holding capacity, full street manners. Good for bolt-on builds running near factory power. Stage 2 Sports uses a more aggressive friction material (cerametallic or sport disc) with stiffer pressure plate — handles meaningful power increases (turbo upgrades, supporting mods) with somewhat firmer pedal effort and slightly less smooth engagement than Stage 1, but still streetable. Hyper Single is Exedy's flagship single-disc performance clutch — significantly higher clamp load, sprung hub for shock dampening, and far higher torque capacity. Hyper Single is the right call for built engines, big turbo setups, and dedicated street/strip cars. For anything beyond Hyper Single's capacity, Exedy's twin-plate Hyper Twin handles 600+ horsepower applications.
