Double Bearing Birdcage Assy Left Rear

The Double Bearing Birdcage Assy Left Rear from Ti22 PERFORMANCE is a precision-engineered differential locating component purpose-built for sprint car racing and high-performance dirt track applications. Designed for the driver-side rear position, this birdcage assembly serves as the structural backbone of modern sprint car rear ends, maintaining absolute geometry under extreme lateral and longitudinal loads. Whether you're upgrading an existing setup or building a new race car from the ground up, this component is essential for drivers and teams who demand maximum chassis control and consistent weight transfer characteristics on the track.

Constructed from lightweight aluminum and finished in black anodized coating for corrosion resistance and durability, the Double Bearing Birdcage Assy Left Rear incorporates dual bearing support with a 2.750-inch inner diameter bore for precise axle shaft alignment. The adjustable design allows tuners to fine-tune rear-end geometry and pinion angle relative to track conditions and setup preferences, critical factors in managing traction and preventing unwanted yaw during acceleration and braking. All necessary hardware is included, simplifying installation and ensuring compatibility with Ti22 PERFORMANCE's ecosystem of rear-end components. The black anodized finish not only protects against oxidation but also reduces heat absorption in the aluminum structure.

This driver-side assembly is ideal for sprint car racers, fabricators, and rear-end specialists who understand the critical relationship between birdcage design and overall chassis performance. Installation integrates seamlessly with standard sprint car rear housings and OEM-style differentials common in 410 and 360 sprint car classes. The 4.7-pound weight and compact footprint (8.4 x 6.8 x 10.3 inches) ensure minimal impact on unsprung weight while maximizing structural rigidity. Teams investing in this component benefit from improved cornering consistency, reduced tire wear patterns, and greater predictability during setup adjustments—advantages that compound over a full racing season.
