Description

The USA Standard Gear Dana 44 Open Differential Spider Gear Set is engineered to provide enhanced off-road control and performance for your Jeep JK. This specific set is designed for the rear Dana 44 axle and features 30-spline compatibility. It is suitable for 2007-2018 Jeep Wrangler JK models, but it is explicitly stated that this set does NOT fit Rubicon models. This spider gear set is precision-machined to meet or exceed Original Equipment (OE) specifications. This ensures a direct fit and reliable performance, contributing to the long-term durability of your drivetrain. The set includes all necessary components for installation, such as side gears, pinion gears, a cross pin shaft, and a cross pin bolt, ensuring a comprehensive solution for differential repair or upgrade. When installing this spider gear set, it is important to ensure compatibility with your specific Jeep JK model. For optimal performance and longevity, professional installation is recommended to ensure all components are correctly seated and torqued according to manufacturer specifications.
