OE Pro 91142429400 Shift Coupler Boot Outer Firewall

The OE Pro 91142429400 is an outer shift coupler boot designed for classic air-cooled Porsche 911, 912, and 930 models. This rubber boot is located at the firewall on the gearbox side of the coupling, where the transmission shift rod enters the body center tunnel.

Key Features:

• Seals the shift coupler from moisture, dirt, and debris that can damage sensitive shift linkage components
• Replaces old, hardened, and cracked original boots that compromise shifting performance
• Molded to OE dimensions and shape for easy installation and original appearance
• Heat and ozone resistant rubber material provides durability while remaining flexible
• Essential for maintaining precise shifter adjustment and smooth operation

This outer boot closes off the round opening in the center tunnel bulkhead, preventing environmental contamination of the shift mechanism. Regular inspection and replacement of worn shift coupler boots helps maintain the precise adjustment required for optimal shifting performance in classic Porsche manual transmissions.
