Z33 350z/Z34 370z & RZ34 Extended dual stud diff cover (Cover only)

The GKTECH Z33 and Z34 dual stud diff covers were purpose designed in house for grip racing, drifting and drag racing. With the Z33 and Z34 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

- Internal stainless steel baffle to replicate OEM fluid flow and distribution
- Proprietary Aluminium Alloy used for casting
- Added stud mounting support ribs
- Dual stud mounting option to suit polyurethane and solid bushings SOLD SEPARATELY
- Cooling fins for increased passive coolant efficiency

- 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.

To further make this more accessible for everyone, we've been working hard on ensuring a suitable mounting option for everyone - from solid bushing dual stud, polyurethane dual stud options, bolt in or weld in bushings etc. Even including diff bush removal tools when needed!
