It works automatically and smoothly with no maintenance, so it suits street, tow, and trail use. Unlike an on\/off locker it stays quiet and predictable, which makes it a popular full-time traction upgrade for the AAM 9.5in axle.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Helical gear limited-slip differential\u003c\/li\u003e\n\u003cli\u003eAxle: AAM 9.5in (rear)\u003c\/li\u003e\n\u003cli\u003eRing gear diameter: 9.5in\u003c\/li\u003e\n\u003cli\u003eSpline count: 33\u003c\/li\u003e\n\u003cli\u003eGear ratio: Fits all ratios\u003c\/li\u003e\n\u003cli\u003eNo maintenance or friction additive required\u003c\/li\u003e\n\u003cli\u003ePart number: 914A643\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAxle Fitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFits the AAM 9.5in 33-spline rear axle used in 2003-2013 Dodge\/Ram 3\/4 and 1-ton trucks.
