{"product_id":"gm10-2-73-up-28-spline","title":"GM10 2.73 UP 28 Spline","description":"\u003cp\u003eGM 10 bolt with 8.5″ ring gear with heavy duty diff cover, for 2.73 and numerically higher gear ratios and 28 spline axles. Shifter and cable not included.\u003c\/p\u003e\u003cp\u003eOX Locker is a selectable locking differential: a driver-operated shift fork and ring design, similar to a manual transmission, that switches between normal open-differential handling on the road and 100% lock for traction off-road. The internal engagement is always the same fully mechanical mechanism regardless of how it's actuated, cable, air (80-120 PSI, optimal at 85 PSI), or electric, so you get on-demand control instead of the always-on engagement of an automatic locker.\u003c\/p\u003e\u003cp\u003eEach unit is built from forged components in a 4-pinion design, with draft-angled engagement teeth that seat tighter as torque increases so the lock won't disengage under load. Installation needs no internal plumbing or housing modification, there's no break-in period, and most applications run on standard stock bearings. OX has built selectable lockers for over two decades around a \"reliability through simplicity\" philosophy, and every unit carries a 1-year manufacturer warranty.\u003c\/p\u003e","brand":"OX Locker","offers":[{"title":"Default Title","offer_id":45278091214914,"sku":"GM10-273-28","price":1160.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1476\/5984\/files\/GM-10-Bolt-locker-n-cover.png?v=1790480714","url":"https:\/\/www.skinnypedalracing.com\/products\/gm10-2-73-up-28-spline","provider":"Skinny Pedal Racing","version":"1.0","type":"link"}
