Shift Rod Adjuster, for Early Style Coupler

EMPI Shift Rod Adjuster for Early Style VW Couplers

Vehicle Fitment and Compatibility

The EMPI 5528 Shift Rod Adjuster is designed specifically for air-cooled Volkswagen applications utilizing the early-style shift coupler, equivalent to OEM part number 111-711-175B. This component is essential for custom VW projects, including sand rails, dune buggies, and shortened chassis where standard shift linkage lengths no longer apply. It provides a mechanical solution for correcting shifting geometry and eliminating play caused by worn or bent rods.

Product Features and Application

This kit includes the threaded adjuster and the necessary adjusting nut. It is engineered to be welded directly onto the shift rod, allowing for precise fine-tuning of the linkage. This is particularly useful in rail applications where the distance between the shifter and the transmission nose cone has been modified. By installing this adjuster, you gain the ability to dial in your gear engagement without having to repeatedly cut or re-weld the rod.

Pro Tech Tips for Installation

Clean Surfaces for Welding: Since this installation requires welding, you must thoroughly prep the shift rod. Grind away all paint, grease, and old debris until you reach bare metal on both the rod and the adjuster. A high-quality, deep-penetrating weld is required to handle the mechanical stress and torque applied during gear changes.

Account for Thread Travel: When measuring your shift rod for shortening, ensure you set the adjuster to the middle of its threaded range before welding. This provides you with equal adjustment travel in both directions, allowing you to lengthen or shorten the linkage as needed once the body or seats are installed.

Verify Rotational Alignment: Before performing the final weld, "tack" the adjuster in place and test the rotation. The coupler must be perfectly clocked relative to the shift finger in the transmission. If the adjuster is welded at a slight angle, it can cause the shifter to bind or make it difficult to engage reverse and third gear.
