Winters Quick Change Gear Set 4400 Series 6 Spline 4.11 4.47 3.78 4.88 5.30 4.49 Steel WIN4403

If you're running a quick-change rear end in bracket racing, drag racing, or circle track competition, swapping gear ratios between rounds is non-negotiable. The Winters 4400 Series Quick Change Gear Set eliminates the need to break down your entire differential, letting you dial in the perfect ratio for track conditions, weight transfer, and engine power band in minutes. Built from high-strength steel with precise 6-spline engagement, this gear set delivers the durability and accuracy you need when every tenth of a second counts.

The dual-ratio configuration—4.11/4.47/3.78 and 4.88/5.30/4.49—gives you flexibility across multiple racing classes and track layouts without investing in separate differentials. Simply pull the carrier, swap the gear set, and you're ready to roll.
