Kartboy Rear Diff Crossmember Bushings Standard Set



  • Q: just to be clear  Tim P.8 years ago

    These go between the cross member and the frame above the differential carrier right? Not the outriggers under the back seats. Above the cross member would require 4 bushings or 2 kits right? These look similar to the oem but the oem has a metal sleeve around their's.

      A:  Correct, this will attach to the outrigger/crossmember mounts between the subframe. For better information Kartboy has an installation guide on their website. This is used in conjunction with the OEM bushing to help fill voids.

  • Q: Fitment question   driftingrotaryz187198 years ago

    Fitment question, is this suppose to eliminate the metal plate that's found above my rear diff crossmember on my GC?

      A:  No these will not remove anything these are simply inserts to help prevent diff clunking.

  • Q: Legacy GT fitment problems  Charlie Tango9 years ago

    I have an 07 Legacy spec.B on which I tried to fit this part (KB-003-DIFF) onto; however, I could not find a correct place anywhere on my car to install it. I called my tuning shop, they weren't any help. I called Whiteline (because I didn't have time to email Kartboy and wait for a response), they didn't have the right information. Is anybody sure this part actually fits on my car, and if so, where? Thanks.

      A:  Pull the plate where the ARB is on each side for one set. Then in front of the tow arm in the front will be the same thing. pull the plate and place a bushing in there. You will use 4 of the bushings that are the same thickness.

  • Q: Are these the same as the Rear Diff Lock Bushings?  laplacexformofs1279410 years ago

    I have heard the Rear Differential Lock Bushings called about 20 different things, and there are around 3 different companies that make bushings that look very similar. Are these the Lock Bushings? Thanks!
  • Q: install only this?  dman70311 years ago

    Hi I am wondering if it would be beneficial to install these but not the differential mount bushings (turn in race). I am looking to install either one, which is easier to install, quieter, and will give better performance?

      A:  I think that these would be easier to install, and quieter as well, but I also think you would see much greater performance with the rear diff bushings, as that will have more of an affect on the rear diff movement than these would. Thanks, Rick

  • Q: Install on GC  Boxercide12 years ago

    Everything I've been able to find says that the large thin bushing is used on the GC... but how? In addition to the large thick bushing? Or by itself? On top of the thick bushing or on bottom? Nobody seems to know.
    • 1 of 1 people found the following answer helpful

      A:  Very good question. The larger thin bushing is used on GC/GF chassis. So the larger thick bushing is not used when installed on the GC/GF. This bushing will be placed on top portion of the diff support bar, where as on GD's for example you would use the thicker bushing.

  • Q: question about the install  irvin78787812 years ago

    for a 2007 wrx tr. i use the large thick bushing on top and the thick small one on the bottom right? this is what i seem to be finding on the net just want to double check.
    • 0 of 0 people found the following answer helpful

      A:  Yes you are correct. The Larger thin bushing is designed to work on the GC (1993-2001) Impreza, where as the larger thicker bushing is to be used on the GD 2002-2007 Impreza.
