NEW TECHNOLOGY

Among the many new design features is an integrated ring gear bolt locking system engineered to prevent the backing out of Ford 9” 'Trac-Loc' bolts.
Fully reusable and able to resist the high torque loads applied to bolt removal, the locking tabs are designed for disassembly and reassembly for fast pit work on ring gear swaps compared to all other bolt locking systems.

Key to the design is the ability to oppose them adverse effects of axle shaft eccentricity caused by typical steering joints, thereby overcoming a common problem with front applications where the differential is offset too far toward one wheel.

Achieving new levels of load, wear and impact resistance, the RD249CE case is 290% stronger overall compared to standard lockers. Designed with deeper locking engagement, the RD249CE ensures locking functionality is retained even after sustaining significant clutch gear tooth damage from locking under throttle.
Engineered with improved internal lubrication, the RD249CE Air Locker also caters for the use of load bolts (sometimes known as pegging).
