Lokar’s ACA-1800 linkage kit is designed to connect GM-style automatic transmissions to a steering column shift arm using a precision-machined, adjustable setup. It features a 21" stainless steel rod that can be trimmed and bent to fit custom engine bay layouts, making it ideal for applications where routing around headers, frame rails, or brake components is necessary.

The rod uses a 3/4"-48 spline on both ends, allowing full rotational clocking for precise shift alignment. The included billet aluminum arms mount to both the transmission selector shaft and column shift lever, secured with high-strength fasteners. Delrin bushings are used at pivot points to minimize play and ensure smooth, positive engagement.

This kit is compatible with most GM transmissions, including TH350, TH400, and 700-R4. All hardware is included for a bolt-on installation, with both metric and SAE nuts for selector shafts.
