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 1990-1993 Acura Integra 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 DA chassis to simply pop in the more robust axles found in the RSX Type S. 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.

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).
DA K Swap Axle Option:
One pair of USDM 2002-2006 Acura RSX Type S Axles (Driver + Passenger Side)
The B-Series Axle Option requires the inboard joints to be swapped between the pair of RSX Type S axles. 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 RSX Type S axles. (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: 103-0001).
I’m not going to go this route since I’m making stock power and don’t want to run hybrid axles with spacers, but this is a super helpful reply so thank you.
the back side of the karcepts hub looks basically identical to the ones i’m looking at save for the splines
I think I’ll pull the trigger on the stock spec ebay ones and update everyone on how it goes.
I also emailed Karcepts to let them know that there might be demand for an oem spec hub for the da9 since we don’t have any other options.
Update: I got an email back from Brian at Karcepts and he said they have been thinking about making OE spec replacement hubs for DA’s and DC’s for a while but they need to see business slow down for them a little bit before they will have time to develop them. He made no commitment, but this is potentially good news for us nonetheless.
Leave a reply or a like if you would be interested in a set and I’ll let Brian know. Maybe we can get a group buy
