ARB 110510SP Air Locker Differential Thrust Block Replacement Part

The ARB 110510SP is a genuine replacement thrust block designed for ARB Air Locker locking differentials. This precision-machined component plays a critical role in maintaining proper axle shaft positioning and end-float conditions within the differential assembly.

Key Features:

• Genuine ARB replacement part for Air Locker differentials
• Precision-machined for accurate fitment and function
• Installs through the center of the spider block to support the side gear
• Essential for maintaining proper axle shaft end-float in semi-floating axle applications
• Designed to withstand high differential loads and forces

The thrust block is inserted through the hole in the center of the spider block until it sits on the plain side gear. This component is particularly important in semi-floating axle applications where proper end-float must be maintained at the hub end. ARB recommends using thick grease to hold the thrust block in place during differential assembly and installation.

This is a direct replacement component for maintaining or rebuilding ARB Air Locker differentials. Always verify compatibility with your specific Air Locker model number before ordering.
