914Rubber Windshield Wiper offset Isolator for Porsche 914 (All years)

Ensure precise wiper operation in your Porsche 914 with the 914Rubber Windshield Wiper Offset Isolator (part number 914.628.011.20), designed for all 914 models from 1970-76. This reproduction nylon isolator mounts on the wiper shaft, connecting the wiper arm (914.628.301.10) to the linkage and maintaining proper alignment for the SWF 12V wiper system. Only one isolator is required per car, critical for smooth, synchronized wiper motion across the windshield.

PMB Performance, with over 20 years of Porsche 914 expertise, has partnered with 914Rubber for nearly two decades, selling more 914Rubber SKUs than any other retailer. Crafted from high-strength, injection-molded nylon, this isolator resists wear from the shaft’s rotational forces and withstands front trunk conditions—moisture, road salt, and temperatures up to 160°F—unlike factory isolators that crack or shear under stress. Its 10mm inner diameter and offset design ensure a secure fit, reducing play that can cause wiper chatter or uneven sweep patterns.

The offset isolator is a linchpin in the 914’s wiper system, linking the motor’s torque to the wiper arms via the 914.628.101.10 shaft. A degraded isolator can lead to misalignment, motor strain, or incomplete windshield coverage, compromising visibility in adverse weather. This 914Rubber isolator installs easily with the factory nut, referenced in the 914 maintenance manual, and pairs with the 901.628.923.01 female and 901.628.924.00 male bushings for a complete refresh.
