Description

25% off pre buy price - VERY LIMITED QUANTITIES AVAILABLE

The Z33 and Z34 OEM diff cover uses a single stud at the rear which is prone to breakage in high grip/hp setups. We make a diff brace which does help but a dual stud cover is the ideal solution.

What you see here is a CNC Machined 6061-T6 aluminum extended diff cover with dual studs, support for a diff cooler, it's baffled (very important for grip applications) and with an additional 600cc of capacity. 

This item is primarily useful for track use however it is also a very attractive item. From under the rear bumper the diff cover will stand out quite a bit. Our CNC machiend billet diff covers are the original and have been making rear subframes pop since 2012.


- High quality billet aluminium 6061-T6 construction 
- Baffle plate, new studs and new plugs included
- Available in 10 different flavours; black, silver, raw aluminium (uncoated), gold, blue, pink, purple, neo chrome, red or orange.

FAQ'S

Will this fit my car?We can only confirm fitment for the vehicles listed above under "vehicle compatibility". Note that the difference between Z33 and Z34 specific versions is based on the subframe. Z33 350z version is to suit an aluminum subframe and the Z34 370z version is to suit a steel subframe. Do you make these to suit other cars?We have these to suit the S13 4 bolt subframe, S14/S15/R33/R34 2 bolt subframe, Z33 350z and Z34 370z. 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 600cc 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 is 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)Can I use this diff cover if I've done a Z33/Z34 diff conversion in my S-chassis?You can, please select the Z34 diff cover option when ordering. If you don't have our conversion bushings already you will need to purchase them and in this listing select the diff bushing option "Z33/Z34 diff conversion secondary bush (for S14/S15 subframe)"
