The ARB RD157 is not just a replacement; it is a massive upgrade designed to transform your Rubicon’s Dana 44 into a competition-grade axle capable of handling extreme torque.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003eAt Overland Truck Store, we recommend the RD157 for Rubicon owners who are ready to \"build it right.\" This locker is engineered specifically for the Rubicon housing but requires upgrading to \u003cb\u003e35-spline axle shafts\u003c\/b\u003e. By stepping up from the stock 30\/32-spline shafts to 35-spline, you gain a massive increase in axle strength (approx. 30-40%), ensuring you can twist heavy tires in the rocks without snapping a shaft.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8\"\u003eUnlike the factory e-locker which can have engagement delays or electrical gremlins, the ARB uses a reliable pneumatic locking mechanism that engages instantly. It fits both the \u003cb\u003eFront and Rear\u003c\/b\u003e axles of the JK Rubicon, allowing you to standardize your locker setup and eliminate the factory fail points.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003e\u003cb\u003eFeatures \u0026amp; Specs:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"10\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,0,0\"\u003e\u003cb\u003eApplication:\u003c\/b\u003e 2007-2018 Jeep Wrangler JK Rubicon \u0026amp; Unlimited Rubicon.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,1,0\"\u003e\u003cb\u003eAxle Type:\u003c\/b\u003e Dana 44 (Rubicon Housing).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,2,0\"\u003e\u003cb\u003eSpline Count:\u003c\/b\u003e \u003cb\u003e35 Spline\u003c\/b\u003e (Requires Aftermarket Axle Shafts).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,3,0\"\u003e\u003cb\u003eCarrier Break:\u003c\/b\u003e Fits \u003cb\u003e3.73 \u0026amp; Down\u003c\/b\u003e (Numerically Lower) Carrier.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,4,0\"\u003e\u003cb\u003ePosition:\u003c\/b\u003e Fits both \u003cb\u003eFront\u003c\/b\u003e and \u003cb\u003eRear\u003c\/b\u003e differentials.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,5,0\"\u003e\u003cb\u003eStrength:\u003c\/b\u003e Forged gears and two-piece case designed for 35-spline loads.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"11\"\u003e\u003cb\u003eInstaller Note:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"12\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,0,0\"\u003e\u003cb\u003eShaft Upgrade Required:\u003c\/b\u003e This locker will \u003cb\u003eNOT\u003c\/b\u003e fit your stock factory axle shafts.
