Description
A 3.55 gear ratio delivers the ideal balance between acceleration and highway cruising for street-strip applications, while the robust 489 case and 29-spline pinion provide the durability to handle sustained performance driving. If you’re building or upgrading a Chrysler 8.75-inch rear end, this complete housing kit eliminates guesswork and ensures OEM-spec compatibility without the need for custom fabrication. Drop it in, bolt it down, and focus on what matters—extracting power from your engine.
