$325.00

Karcepts 36mm Swap Hubs provide the SOLUTION for upgrading to OEM Honda/Acura “36mm” axles in high powered 1992-2000 Civics and 1994-2001 Integras. Perfect for K-Swaps; but can also be used with high output B, D, F, H, and J-Swaps.

***AS OF 1/25/21 WE ARE CARRYING THE NEW "V2" VERSION OF KARCEPTS SWAP HUBS***
Make sure you select the correct part #

Like breaking axles? Level 1 Swap Axles just don't cut the mustard with a rating of only 200WHP. Whose K-Swap doesn't make over 200WHP?!? Level 2.9 Swap Axles are not much better of an alternative as they still utilize the smaller Civic/Integra/CRX axle spline and will run a good $800 for a pair. This is where OEM Honda/Acura “36mm” axles fit in. They utilize a substantially larger axle spline which allows them to handle higher horsepower and torque outputs, yet they are extremely cost effective. This larger axle spline is observed in chassis such as the Acura RSX-S, Honda 06+ Civic Si, and Honda Prelude. Unfortunately, this larger spline is unable to be installed directly into OEM Civic, Integra, or CRX hubs, so that is where our Karcepts 36mm Swap Hubs come into play. Karcepts Hubs are modeled almost exactly after the OEM Honda/Acura hubs they replace, except that the splines now match that of the larger “36mm” axles.

Side Note: Internet forum terminology has named the larger OEM spline axles “36mm”. We have conformed to that terminology as not to confuse others. However; for educational and axle identification purposes, “36mm” is actually the socket size used for the axle nut of these larger spline axles. The larger spline diameter in reality measures 29.50mm on these axles.

  • CNC turned out of billet high strength chrome-moly steel
  • Oil quenched and tempered
  • Maintains OEM rotor-centric attributes
  • Designed for the larger OEM 29.50mm axle spline (36mm axle nut socket)
  • OEM “36mm” axles have proven time and again to easily sustain 500+ WHP
  • "V2" Version does not include STUDS, you must purchase one of the following:

    IF YOU NEED ANY OTHER HUBS, PLEASE CONTACT US! IF YOU ORDER THE INCORRECT HUBS THERE ARE NO RETURNS!

  • Use Karcepts P/N: KWH01-V2 to replace factory OEM Honda hub P/N: 44600-S04-980 found on 70% of USDM 1992-2000 Honda Civic models.  These vehicles use a 38mm I.D. wheel bearing and also have factory brake discs which measure 240mm (or 9.44 inch) O.D.

    Use Karcepts P/N: KWH02-V2 to replace factory OEM Honda/Acura hub P/N: 44600-S04-A00 found on ALL USDM 1994-2001 Acura Integra models (excluding Type-R) and 30% of USDM 1992-2000 Honda Civic models.  These vehicles use a 43mm I.D. wheel bearing and also have factory brake discs which measure 262mm (or 10.31 inch) O.D.

    Karcepts 36mm Swap Hubs / 94-01 Integra (excluding Type-R) / Big Brake 92-00 Civic / 262mm (10.3") Brake Rotor / 43mm Wheel Bearing

    Karcepts 36mm Swap Hubs offer one of the most reliable and economical drivetrain solutions for track and high horsepower applications. These hybrid hubs share identical external dimensions with the original 1994-2001 4-lug Integra and “big brake” 1992-2000 Civic wheel hubs they replace; however, their center bores have been machined to accept the larger 28 tooth spline pattern found on “36mm” Honda/Acura axles. This allows EG, EK, and DC2 chassis to simply pop in the more robust axles found in vehicles like the RSX Type-S, 06-11 Civic Si, and 97-01 Prelude. Prior to this solution, simple all-motor K-Swaps using stock wheel hubs with standard “32mm” (26 tooth spline) axles would experience far too frequent axle snapping incidents. Karcepts 36mm Swap Hub customers making 8 second passes with their 1,000 WHP Civics have reported the ability to run a full race season on the same pair of factory Honda/Acura “36mm” axles without failure. Please note, axles subjected to high HP race applications should be treated as wear items, though historical data has shown OE “36mm” axles can handle much abuse.

    • CNC turned from billet chromoly steel
    • Oil quenched and tempered for improved fatigue strength
    • Accepts the larger 28 tooth spline axles (these use a 36mm axle nut socket)
    • Precision ground 43mm bearing journals
    • 4x100mm bolt pattern
    • Maintains OE rotor-centric attributes and offset
    • Wheel studs not included
    • Sold in pairs

    Fits:
    1994-2001 Acura Integra models (excluding Type-R)

    1992-2000 Honda Civic models with 262mm (10.3") diameter brake rotors and 43mm I.D. wheel bearings

    1992-2000 Civics left Honda's factories with two hub sizes. OE “big brake” (10.3" diameter rotor) Civics shared the same hub, knuckle, and 43mm I.D. wheel bearing with 1994-2001 4-lug Integras. OE “small brake” (9.4" diameter rotor) Civics came with a smaller hub, a smaller knuckle, and a smaller 38mm I.D. wheel bearing. It is not always possible to determine hub size based on the vehicle's trim level, so the easiest way to confirm which Karcepts hubs to order is by measuring the diameter of the factory brake rotors. If the vehicle has an aftermarket brake kit, then the only way to know hub size is to measure the wheel bearing or hub itself. Karcepts 36mm Swap Hubs designed to fit 1992-2000 Honda Civic models with 240mm (9.4") diameter brake rotors and 38mm I.D. wheel bearings may be purchased here.

    Wheel stud options:
    OE Honda Stud: 90113-SM1-005
    ARP 1.85" Long Stud (4pk): 100-7709
    ARP 2.85" Long Stud (4pk): 100-7711 <-- BUY FROM XENOCRON

     

    Axle Lengths:

    It is critical to use proper length axles for the chassis and transmission utilized. There are several companies making specific "36mm" axles already built to the proper lengths. However, if you are able to score some premium OE Honda/Acura axles from a salvage yard, below are some combinations we have verified (We do recommend using only original equipment Honda/Acura axles, as their joints are far stronger than the generic auto parts store axles. Try searching car-part.com to view a database of salvage yard inventory across the country).

     

    EG/EK/DC2 K-Swap Axle Options:

    Option #1 - One USDM 2002-2006 Acura RSX Type-S Driver Side Axle + One USDM 2006-2011 Honda Civic Si Passenger Side Axle (most ideal length)

    Option #2 - One USDM 2002-2006 Acura RSX Type-S Driver Side Axle + One USDM 1997-2001 Honda Prelude Base Driver Side Axle (slightly shorter than ideal length, but still within specifications)

    Option #3 - One USDM 2002-2006 Acura RSX Type-S Driver Side Axle + One USDM 1997-2001 Honda CRV Driver Side Axle (slightly longer than ideal length, but still within specifications)

    Option #4 - One pair of USDM 2002-2006 Acura RSX Type-S Axles (Driver + Passenger Side) with inboard joints swapped between the pair

    Option #5 - One pair of USDM 2006-2011 Honda Civic Si Axles (Driver + Passenger Side) with inboard joints swapped between the pair

    Option #6 - One pair of USDM 1997-2001 Honda Prelude Base Axles (Driver + Passenger Side) with inboard joints swapped between the pair

    Options #4, #5, and #6 require the inboard joints to be swapped between the pairs of axles listed. This joint swap effectively adjusts (corrects) the axle lengths, and is mandatory to avoid issues. To perform an inboard joint swap: (1) Take one pair of axles mentioned above. (2) Remove (or cut) the large boot clamps on the inboard joints. (3) Slide the inboard joints off from each axle without disturbing the tripod bearings (hold axles vertically and lift joints straight upward). (4) Re-install the inboard joints to the other respective axle (i.e. move the male inboard joint to the original female axle; move the female inboard joint to the original male axle). (5) Pop the boots back into position on the joints and re-secure original boot clamps or install new boot clamps. You can find boot clamps at most auto parts stores that do not need any form of special tool in order to re-secure the boots to each joint (Beck Arnley P/N: 103-0001).

    EG/EK/DC2 B Series Axle Option:

    One pair of USDM 2002-2006 Acura RSX Type-S Axles (Driver + Passenger Side) + One Karcepts K-Series Axle Spacer for B-Series Transmission
