Description

The USA Standard Master Overhaul kit is a comprehensive differential overhaul solution specifically designed for the Dana Spicer 44 found in the TJ Rubicon. This kit streamlines the overhaul process by consolidating all essential components into a single part number, offering both time and cost savings for the installer. Crafted with quality in mind, this overhaul kit features Koyo bearings and races, known for their durability and performance. The included components cover every aspect of a differential rebuild, including carrier bearings and races, pinion bearings and races, a new pinion seal, a comprehensive shim kit for precise gear setup, ring gear bolts, a pinion nut, a crush sleeve for proper pinion depth adjustment, oil baffles and slingers to manage lubrication, thread locker for secure fasteners, and a marking compound with an applicator brush for accurate gear pattern analysis. A tube of silicone sealant is also included for a reliable seal. USA Standard Gear designs these master overhaul kits with the general installer and DIY customer in mind, aiming to provide unmatched reliability and assurance for long-term vehicle repair.
