It does not need air, wiring or a switch.\u003c\/p\u003e\u003ch2\u003eConstruction\u003c\/h2\u003e\u003cp\u003eYukon builds it with a forged case and 8620 internals. The clutch teeth use a larger radius at the base, which Yukon says makes them up to 350 percent stronger than back-cut designs and helps the locker hold up to shock loading and catastrophic axle failure. Assembled in the USA.\u003c\/p\u003e\u003ch2\u003eCheck before you order\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYour ring gear ratio has to be 4.10 or numerically lower.
