{"product_id":"36mm-swap-hubs","title":"36mm Swap Hubs","description":"The Karcepts 36mm Swap Hubs provide a robust and cost-effective drivetrain upgrade for track use and high-horsepower builds. Engineered to replace the original \"Small Brake\" hubs found on 1992-2000 Honda Civics, these hybrid units feature a center bore precisely machined to accommodate the larger 28-tooth spline pattern of \"36mm\" Honda\/Acura axles. This critical modification enables the direct use of stronger axles from models such as the RSX Type S, 2006-2011 Civic Si, and 1997-2001 Prelude, significantly mitigating the risk of axle failure experienced with smaller \"32mm\" (26-tooth spline) axles in high-power K-Swap or all-motor applications.\n\nCustomers have reported running full race seasons with 1,000 WHP Civics on OE \"36mm\" axles without failure, though it's noted that axles in high-HP applications should be treated as wear items. The hubs themselves are CNC turned from billet chromoly steel, then oil quenched and tempered to enhance fatigue strength. They feature 38mm bearing journals and retain the original equipment (OE) rotor-centric attributes and offset, ensuring proper fitment with the existing brake setup.\n\nKey specifications include a 4x100mm bolt pattern and the 38mm I.D. wheel bearing journal. Wheel studs are not included and must be purchased separately. These hubs are sold in pairs.\n\n**Fitment:** These hubs are specifically designed for 1992-2000 Honda Civic models equipped with 240mm (9.4-inch) diameter \"Small Brake\" rotors and 38mm I.D. wheel bearings. It is crucial to verify your vehicle's hub size by measuring the brake rotor diameter, as trim level alone may not be indicative of the original hub size. For \"Big Brake\" (10.3-inch rotor) Civics with 43mm I.D. wheel bearings, a different Karcepts hub set is required.","brand":"Karcepts","offers":[{"title":"Default Title","offer_id":52871998308664,"sku":"KCH-CIV-36-4X100-SB","price":400.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/36mm-swap-hubs","provider":"MOTORMIA","version":"1.0","type":"link"}
