This unit drops directly into your 2016-2023 Tacoma's rear differential housing, replacing the entire ring and pinion, open carrier, and associated hardware as one assembled unit. The YDAT8.75-430 is the correct choice for open-differential Tacomas that need a gear ratio change to match larger tires. The 4.30 ratio is widely used on Tacomas running 35-37 inch tires to restore factory driveability and cruise RPM.\u003c\/p\u003e\u003ch4\u003eKey

E-Locker?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Third-generation 2016-2023 Tacomas equipped with a rear electronic locker use the T8.75 housing. Open-differential Tacomas without the locker option also use the T8.75 on some configurations. Confirm by checking your option codes or the axle housing tag.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Is 4.30 a good ratio for 35-inch tires?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes. 4.30 is one of the most popular ratio upgrades for 2016-2023 Tacomas running 35-37 inch tires. It restores low-end grunt and reduces the RPM deficit caused by the larger tire diameter at highway speeds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Can I install the YDAT8.75-430 myself?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The dropout design makes the installation more accessible than a traditional cover-style differential. Drain the fluid, remove the axle shafts, pull the old third member, and install the new unit. Professional installation is still recommended for correct torque, pattern verification, and fluid fill.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Do I need to match the front and rear ratios?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, for 4WD applications the front and rear differential ratios must match to avoid driveline bind during 4WD engagement. Plan a front regear at the same time as the rear when changing ratios on a 4WD Tacoma.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What gear oil should I use?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Toyota specifies 75W-90 GL-5 synthetic gear oil for the T8.75 differential. Fill to the bottom of the fill plug hole.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Is this the right part for a Tacoma with a factory E-Locker?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. If your Tacoma has the factory rear E-Locker, you need the YDAT8.75-430E, which includes the E-Locker compatible carrier. Using an open carrier will disable the E-Locker function.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What is the warranty on YDAT8.75-430?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yukon Gear backs this assembly with a Lifetime Limited Warranty.
