The GKTECH Z33 dual stud diff covers were purpose designed in house for grip racing, drifting and drag racing. With the Z33 OEM diff cover using a single stud at the rear it is incredibly prone to breakage in high grip/hp setups. We are confident this is the BEST aftermarket diff cover available!
Through a lengthy design phase, destructive testing and a lot of real world drifting and drag car testing - this is the end result. It's no secret our billet dual stud diff covers were a popular piece, but by going down the route of proprietary Aluminium Alloy used for casting we've been able to make these more accessible and more affordable than EVER before.
Stronger than OEM in EVERY way possible, added stud mounting ribs, increased thickness, single and dual stud compatible, increased oil capacity, added cooling fins and much much more.
Check out the full list of benefits here:
- Increased overall thickness by 10%
- Increased oil capacity by 0.5L

- Additional M18 x 1.5 port for use with external coolers
- Additional M14 x 1.5 port for compatibility with RZ34 OEM temperature sensor
- M14 x 1.5 to NPT adapter for aftermarket temperature sensors (non RZ34)
- Magnetic drain plug
- Flux AN fittings throughout
- Durable black powder coating
To ensure our diff cover is stronger than OEM we did some in-house destructive testing, resulting in over a 20% strength increase in single stud application and even more in dual stud configuration: Breaking our 15 tonne hydraulic press.
NOTE: Not compatible with the use of a diff brace, including our own. We strongly suggest using this cover in a dual stud format.

FAQs
Will this fit my car?We can only confirm fitment for the vehicles listed above under "vehicle compatibility". Note that the difference between
Do you make these to suit other cars?
We unfortunately don't offer these for any other vehicles at present.
What's the advantage of using the GKTech extended diff cover?
This beautiful piece of engineering provides an extra 500cc capacity over the standard cover, incorporates a secondary diff stud and has the provision for an external cooler. This extra capacity helps regulate diff oil reducing wear of your LSD/bearings.
What modifications are required, is this hard to fit?
The secondary diff bush must be installed using our template. It's pretty straight forward and so long as you have a standard sized holesaw, and a welder if opting for the weld in bush, it's easy.
Is there anything else needed for installation?
No, the secondary diff bush will be included, diff studs are included along with all plugs, breather etc.
Will this diff cover work with a car that has 4WS?
No, this cover won't fit a 4WS subframe.
Can I use this cover in conjunction with the OEM diff bushing?
It is not recommended and we would advise strongly against it. Using a secondary diff stud is really advantegous in helping get power to the ground. If you were to have 1 bush solid mounted and the other as the OEM rubber bushing, the loads would be unqeual and would put unnecessary load on the cover. A Polyurethane bushing may be ok but we do recommend the use of a solid primary bush (which we do have available separately)
