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.
