MAHLE SJR-XL Stretch Joint Ring Extra Large Piston Pin Retainer

The MAHLE SJR-XL is an extra-large stretch joint ring (piston pin retainer/circlip) engineered to OEM specifications for secure piston pin retention during engine operation. MAHLE is a globally recognized leader in engine component manufacturing, producing parts that meet or exceed original equipment standards for durability, dimensional accuracy, and reliability.

Key Features:

• Extra-large (XL) sizing for compatibility with larger bore piston applications
• Precision-engineered stretch joint design for consistent, secure snap fit in piston pin groove
• Manufactured to OEM-grade tolerances for exact dimensional fitment
• High-strength material construction resists deformation under high-load engine conditions
• Designed for use in engine rebuild and piston assembly applications

MAHLE piston pin retainers are a critical component in maintaining proper piston pin alignment and preventing lateral pin migration during engine operation. The SJR-XL is suited for professional engine builders and rebuilders requiring OEM-quality retention components in larger displacement or heavy-duty applications.
