Adj. Billet Column Arm Kit TH350/400/700R4

The LOKAR Adjustable Billet Column Arm Kit (ACA-1800) is a precision solid-rod column shift linkage assembly engineered for hot rod and custom vehicle builders working with GM TH350, TH400, and 700R4 transmissions. This aluminum billet kit replaces factory plastic and rubber components with rigid, corrosion-resistant hardware that eliminates play, noise, and inconsistent shift feel common in worn original equipment.

Built from aluminum billet with a natural finish, the adjustable column arm mechanism allows fine-tuning of shift linkage geometry to match custom steering columns, firewall configurations, and transmission mounting heights. The solid-rod design transfers shift input directly from the column to the transmission bracket without deflection or delay. At 1.18 pounds and compact dimensions (5.8" × 1" × 23.3"), the kit integrates cleanly into tight engine compartments while maintaining full adjustability for column heights and transmission positioning variations common in street rods, restorations, and custom builds.

This kit is essential for builders transitioning from column-shift automatic transmissions to modern or performance platforms, or for owners restoring classic vehicles with non-stock engine/transmission combinations. The billet construction resists vibration cracking and corrosion better than OEM plastic assemblies, delivering durable, maintenance-free operation over decades of driving. LOKAR's adjustable design accommodates the dimensional tolerances inherent in hand-fabricated hot rod frames and custom welded firewall modifications, making it the standard choice for high-end restorations and boutique fabrication shops.
