With t\u003cspan\u003ehe 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! \u003cbr\u003e\u003cbr\u003e\u003c\/span\u003eThrough a lengthy design phase, destructive testing and a lot of real world drifting and drag car testing - this is the end result.

This extra capacity helps regulate diff oil reducing wear of your LSD\/bearings.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eWhat modifications are required, is this hard to fit? \u003c\/b\u003e\u003cbr\u003eThe 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. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eIs there anything else needed for installation?\u003c\/b\u003e\u003cbr\u003eNo, the secondary diff bush will be included, diff studs are included along with all plugs, breather etc. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eWill this diff cover work with a car that has 4WS? \u003c\/b\u003e\u003cbr\u003eNo, this cover won't fit a 4WS subframe. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eCan I use this cover in conjunction with the OEM diff bushing? \u003c\/b\u003e\u003cbr\u003eIt 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)\u003c\/div\u003e\n\u003cdiv class=\"desc-no-tab\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"block-template--17511439958316__74d69bdf-8fca-47df-a827-03de5d6c63df-10b8d2ec-5527-41af-a9e8-7ac95ba16c29\" class=\"desc-no-tab\"\u003e\n\u003ch2\u003eVEHICLE COMPATIBILITY\u003c\/h2\u003e\n\u003cdiv class=\"vehicle-display\"\u003e\n\u003cdiv class=\"vehicle-compatibility-productpage\"\u003e\n\u003cdiv class=\"model-section\"\u003e\n\u003ch3 class=\"model-title\"\u003eNISSAN\u003c\/h3\u003e\nRZ34 Z\u003cbr\u003eZ33 350Z\u003cbr\u003eZ34 370Z\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"model-section\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"model-section\"\u003e\n\u003ch3 class=\"model-title\"\u003eINFINITI\u003c\/h3\u003e\nG35\u003cbr\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"block-template--17511439958316__74d69bdf-8fca-47df-a827-03de5d6c63df-bf2827d0-8aae-41ee-84f2-1c4eb0d61345\" class=\"desc-no-tab\"\u003e\n\u003ch2\u003eUSER GUIDE(S)\u003c\/h2\u003e\n\u003cdiv class=\"user-guides\"\u003e\n\u003ch3\u003eINSTALL VIDEOS\u003c\/h3\u003e\n\u003cdiv class=\"col-2\"\u003e\n\u003cdiv class=\"video-wrapper\"\u003e\u003ciframe class=\"video\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/0p6u6ne87tY\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"text-container\"\u003e\n\u003ch3 class=\"heading\"\u003eASSEMBLY GUIDES\u003c\/h3\u003e\n\u003ca href=\"https:\/\/us.gktech.com\/cdn\/shop\/files\/Z334-CAST_-_Customer_ASM.pdf?v=1621417486646805304\"\u003eDownload Z334-CAST - Customer ASM\u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"GKTech","offers":[{"title":"Default Title","offer_id":47334361891003,"sku":"GKTECH-Z334-CAST","price":309.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/9556\/2683\/files\/image_484d4052-c9f0-4399-bf95-43971cc43951.jpg?v=1767431608","url":"https:\/\/drifthq.com\/products\/gktech-z33-350z-z34-370z-rz34-extended-dual-stud-diff-cover-cover-only","provider":"Drift HQ","version":"1.0","type":"link"}
