The Lokar Turbo 350 (TH350) Transmission Kickdown Cable Kit is the industry standard for connecting a GM TH350 3-speed automatic transmission to virtually any carburetor or induction setup. Featuring Lokar’s signature "U-Cut-to-Fit" outer housing and inner wire, it allows engine builders to tailor the exact cable routing required for smooth, crisp downshifts under wide-open throttle. Product Overview & Performance The TH350 transmission relies on a kickdown cable to actuate the downshift valve inside the transmission valve body when the accelerator pedal is floor-boarded. OEM factory plastic-sheathed kickdown cables are rigid and notoriously difficult to route on custom hot rod manifolds, tunnel rams, or high-rise intake setups. Lokar solves this by enclosing a high-tensile stainless steel inner cable inside an extruded PTFE (Teflon) liner. This low-friction internal sleeve prevents wire drag, resists severe engine bay and exhaust heat, and ensures precise, instant kickdown engagement without sticking or binding. Housing & Finish Configurations Lokar offers three distinct outer housing choices paired with color-matched hardware to complement your engine bay: Braided Stainless Steel: Features a classic high-shine stainless steel braid with natural brushed or polished aluminum fittings (Part # KD-2350HT). Hi-Tech Black Stainless Steel: Features a sleek black braided stainless steel sheath fitted with black anodized aluminum hardware (Part # XKD-2350HT). Universal Black: Features a durable black polyethylene outer housing paired with clean aluminum fittings for a factory-style finish (Part # KD-2350U). Key Features & Design Highlights "U-Cut-To-Fit" Custom Sizing: Both outer housing and inner wire trim easily to match custom firewall-to-carburetor spacing and non-stock intake heights. Broad Induction Compatibility: Adapts seamlessly to standard single 4-barrel carburetors, tunnel rams, blower manifolds, Weber induction systems, and multi-carb setups. Friction-Reducing PTFE Liner: Extruded PTFE inner sleeve eliminates internal wire friction and binding for long service life. Anti-Fray Aluminum Ferrules: Precision aluminum ferrules clamp securely over cut wire ends to prevent unraveling. Cotter-Free Linkage Design: Clean mounting hardware eliminates slop, set screws, and failure-prone cotter pins. American-Made Quality: Hand-assembled in the USA and backed by Lokar's Lifetime Warranty.

Cutting both together will crush the internal PTFE liner and permanently ruin the inner wire. Mounting Brackets & Springs: For optimal alignment and positive throttle return, mount this kickdown cable using Lokar’s Stainless Steel Carburetor Bracket and Dual Return Spring Kit (sold separately), which anchors securely to the rear carburetor mounting studs.
