Designed to OE specifications for 1984–1986 Corvette C4 models, this strip feeds through the regulator spool to raise and lower the window glass smoothly. Compatible with driver or passenger side doors, this high-quality replacement ensures proper alignment and reduced binding under power operation. Over time, the original ribbon's teeth can wear down, causing slipping, inconsistent motion, or complete window failure—even when the motor still functions. This direct-fit replacement is constructed from durable nylon to provide long-lasting performance and outlast OE materials.
