This unit drops directly into the 2016-2023 Tacoma's 8-inch rear differential housing, replacing the ring and pinion, open carrier, and associated hardware as one complete assembled unit. The YDATV6C-430 is the correct assembly for open-differential Tacoma models using the smaller 8-inch rear end. The 4.30 ratio is a popular upgrade for Tacomas running 35-37 inch tires to restore cruise RPM and low-end torque delivery.\u003c\/p\u003e\u003ch4\u003eKey

Open-differential models use the 8-inch TV6C unit. Check your build sheet or axle housing tag to confirm your axle type before ordering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Is 4.30 a good choice for 35-inch tires?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes. A 4.30 ratio significantly improves low-end torque and helps maintain usable RPM at highway speeds when running 35-37 inch tires over the factory 3.73 or 3.91 ratios.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Can I use YDATV6C-430 to replace a T8.75 assembly?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. The TV6C 8-inch and T8.75 assemblies are not interchangeable.
