The GKTECH IS300 / JZX diff bushes are a direct OEM replacement, engineered to eliminate the slop and movement of factory rubber mounts, giving your rear differential a more precise, connected feel.
CNC machined from 6061 T6 aluminium and anodised black for durability and corrosion resistance, each kit also includes all replacement rear hardware for a complete, hassle-free install. Ideal for improving throttle response, rear-end stability, and overall drivetrain feedback - perfect for both spirited street driving and track use.
In addition to limiting the movement of your rear diff, we give the option to raise the diff within the subframe 8mm limiting the angle of your axles on a lowered vehicle. If your car isn't super low, the OEM style solid bush is recommended.

OEM Style or 8mm raised version?
If your car is lowered, go with the 8mm raised version. There are no negatives and it fixes up bad axle angles which cause blown cv's.
NOTE: If using the 8mm raised bushes in conjunction with solid subframe riser bushes, a small amount of trimming/hammering of the transmission tunnel heatshield is required
NOTE #2: The 8mm risers were also designed around the OEM diff/driveshaft/tailshaft, if you have aftermarket driveshafts/tailshaft then it may make contact with the heat shield, which is circumstantial and needs to be checked.

FAQs
What's the difference between your OEM style solid diff bushes and the "raised 8mm" version?Solid is as the name suggests, solid. Where the risers come in to it is if you have lowered your car the axle angles get messed up. The OEM axles don't work well at high angles and as such can blow our CV joints. By raising your diff 8mm you are correcting the axle geometry by 8mm.
Why not go more than 8mm?
The diff physically can not sit any higher in the subframe. To go one step further you can however raise your subframe also.
Will this fit my car?
We can only confirm fitment for the vehicles listed above under "vehicle compatibility". If your car is not listed there, then we don't know if it will fit.
Do you make these to suit other cars?
We only sell the parts listed on our website. If it's not listed on our website, then we don't sell it. Sorry.
What's the advantage of using the GKTech solid diff bushes?
Being solid they ensure that movement of the diff is kept to a minimum within the subframe which is quite common under hard driving conditions.
What modifications are required, is this hard to fit?
No modifications are required, simply install the front bushes and then press the rear bush into the subframe.
Is there anything else needed for installation?
No, we provide hardware to suit the new diff bushings, in terms of the bushes they will arrive as shown in the product photo.
Can I install this myself? If so how long will installation take?
Yes, if the subframe is out the job so take around 30 minutes to install the bushes and diff.
Do these cause much vibration/noise in the cabin?
Not really. Obviously, anything solid or more rigid is going to cause an increase in noise and vibration. However, I'd hardly say that it's noticeable. Chances are if you're installing these you've already got coilovers, your car is lowered, you've got an aftermarket exhaust etc.
