Karcepts 36mm Swap Hubs

Karcepts 36mm Swap Hubs provide the SOLUTION for upgrading to OEM Honda/Acura “36mm” axles in high powered 1988-2000 Civics, 1990-2001 Integras, and 1988-1991 CRX’s. Perfect for K-Swaps; but can also be used with high output B, D, F, H, and J-Swaps.

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 Civic, Integra, and CRX 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
■Maintains OEM rotor-centric attributes
■Includes 2.50" long ARP extended studs
■Designed for the larger OEM 29.50mm axle spline (36mm axle nut socket)
■OEM “36mm” axles have proven time and again to easily sustain 300+ WHP

Use Karcepts P/N: KWH01 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 to replace factory OEM Honda/Acura hub P/N: 44600-S04-A00 found on ALL USDM 1994-2001 Non-ITR Acura Integra models 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.

If you are uncertain which OEM Honda hubs are used on your 1992-2000 Honda Civic knuckles, simply measure the I.D. (inner diameter) of your wheel bearing or the O.D. (outer diameter) of your original factory brake disc and compare with the above.

Use Karcepts P/N: KWH03 to replace factory OEM Honda hubs found on all USDM 1988-1991 Honda Civic and CRX models.

Use Karcepts P/N: KWH04 to replace factory OEM Acura hubs found on all USDM 1990-1993 Acura Integra models.

Use Karcepts P/N: KWH05 to replace factory OEM Acura hubs found on all USDM 1997, 1998, 2000, and 2001 Acura Integra Type-R models. You may also use these hubs on any USDM 1994-2001 Non-ITR Acura Integra knuckle if you desire to convert to 5 lug. Just note that you will also need to upgrade to USDM ITR brake discs and calipers.

The above Karcepts part numbers are valid for USDM vehicles only. We have found JDM and EDM vehicles may differ. Please consult us if your hub application is not specified above.

Install wheel hubs per the procedure called out in the Honda/Acura Service Manual. As instructed, ALWAYS use new wheel bearings for hub replacement as its inevitable you will be placing side loads never intended for the wheel bearings when having to remove the old hub. Wheel bearing type does not change with our hubs, so just use replacement wheel bearings for whatever your application may be.

NOTE: We recommend using only OEM Honda/Acura axles. Trust us; a used and rusty 80,000 mile OEM Honda/Acura salvage yard axle will outlast the generic auto parts store replacement axles by tenfold!


EG/EK/DC2 K-Series Axle Options:
Complete Set (MANDATORY inboard joint swap for 3 options below):

Option #1 - One pair of USDM 2002-2006 Acura RSX-S Axles (with inboard joints swapped between the pair)
Option #2 - One pair of USDM 2006-2011 Honda Civic Si Axles (with inboard joints swapped between the pair)
Option #3 – One pair of USDM 1997-2001 Honda Prelude Base Axles (with inboard joints swapped between the pair)

If needing to perform an inboard joint swap; take one pair of axles mentioned above, cut/remove the large boot clamps on the inboard joints, simply slide the inboard joints off from each axle, and then re-install the inboard joints to the other respective axle (i.e. move male inboard joint to original female axle; move female inboard joint to original male axle). 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).

Left Side (No joint swap; pop in and go!):
One USDM 2002-2006 Acura RSX-S Driver Side Axle

Right Side (No joint swap; pop in and go!):
Option #1 – One USDM 2006-2011 Honda Civic Si Passenger Side Axle
Option #2 – One USDM 1997-2001 Honda Prelude Base Driver Side Axle
Option #3 – One USDM 1997-2001 Honda CRV Driver Side Axle

EF/DA K-Series Axle Options:

Re: Karcepts K-Series Swap Hubs

Nice, but why no highway use...
Typical legal statement just to cover ourselves from lawsuit if someone re-uses a wheel bearing or installs improperly and has a failure on a public road because of it. We are not going to be held responsible for a situation like that.

That's definitely possible, and we keep getting requests for that; however, I would assume most would just want to source themselves some CRV knuckle/hub assemblies to go 5 lug that way (as CRV's use the larger spline as well). I think that would be a more cost effective option. But let me know, am I missing something here? Or is there a specific reason you prefer to go this route vs. a CRV setup? We'll give the customers what they want, but if there is a better option; where not needing a custom part, then there may not be the need.

Re: Karcepts K-Series Swap Hubs

I like McCoy's idea but I think see you're point Brian.

Lets say you did make the 36mm hub set to be used in civic/integra spindles. Would be nice but now we're talking about buying new pads, rotors and calipers.

Or keeping the same pads and calipers and have the rotors redrilled to 5x114 to be a little less cheaper.

Regardless, I still like the idea Kevin. Still have to consider changing the rears to 5x114 as well.

Re: Karcepts K-Series Swap Hubs

I think there may be some 5 lug rotors out there (from different makes) that could still fit with the standard size Integra calipers/pads. So maybe that could be an appealing option to some. But like you said, the rear still has to be taken care of. This still may be something to get into... I'd like to keep hearing feedback/opinons on the matter, so keep it coming!

Re: Karcepts K-Series Swap Hubs

i think the biggest reason is total cost effectiveness and tried and true dependablity. yes u can get some used parts and come out the same but most would rather get new for multiple reasons. me personally i look at my car like its my bed, sure its used but iam put fresh new sheets on it and sleep better at night:silly:
