Lokar Throttle Cable for GM Vortec Tuned Port

The Lokar Throttle Cable for GM Vortec & Tuned Port Injection (TPI) is a high-performance cable solution engineered specifically for GM fuel-injected Small Block V8 engines. Featuring Lokar’s signature "U-Cut-to-Fit" outer housing and inner cable, it allows builders to route a precise, clean throttle line when swapping or detailing Vortec 5.0L/5.7L V8s or classic Tuned Port Injection engines in custom hot rods, trucks, and muscle cars.

Engine Application & Compatibility

This cable assembly features engine-side linkage hardware designed specifically for:

• GM Vortec V8 Engines (1996–2002): 5.0L (305ci) L30 and 5.7L (350ci) L31 engines (Chevrolet C/K Pickups, Tahoe, Suburban, Express Van) running cable-operated throttle bodies.

• GM Tuned Port Injection (TPI) (1985–1991): 305ci and 350ci V8s (Corvette C4, Camaro Z28 / IROC-Z, Firebird Trans Am).

• Vortec / TPI Engine Swaps: Ideal for adapting factory or aftermarket Vortec and TPI intake setups into vintage chassis, eliminating long, unsightly factory cable loops.

Product Overview & Performance

Stock GM factory cables from the late 1980s and 1990s are rigid, bulky, and rarely fit clean engine swap layouts. Lokar solves this by enclosing a high-tensile stainless steel inner wire inside an extruded PTFE (Teflon) liner. This low-friction sleeve resists high engine bay temperatures, eliminates internal drag, and ensures smooth, linear throttle response. Custom aluminum ferrules clamp over the trimmed inner wire ends to prevent fraying during initial setup or adjustment.

Housing & Finish Configurations

Lokar offers three distinct housing styles paired with color-matched end hardware:

• Braided Stainless Steel: Classic high-shine stainless steel sheath paired with natural brushed or polished aluminum fittings.

• Hi-Tech Black Stainless Steel: Sleek black braided stainless steel cover paired with black anodized aluminum end hardware.

• Universal Black: Durable black polyethylene outer housing with clean aluminum fittings for a factory-style finish.

Key Features & Design Highlights

• "U-Cut-To-Fit" Custom Sizing: Outer housing and inner wire trim easily to match custom firewall-to-throttle-body spacing (available in 24", 36", and select 48" lengths).

• Vortec / TPI Linkage Connection: Connects directly to GM Vortec and TPI throttle body linkage cams without slop or binding.

• Friction-Reducing PTFE Liner: High-density PTFE sleeve prevents internal wire wear and binding through tight routing angles.

• Anti-Fray Aluminum Ferrules: Precision aluminum ferrules lock around cut inner wire ends to prevent unravelling.

• Cotter-Free Clevis Design: Clean clevis attachment eliminates set screws and cotter pins at pedal and engine connections.

• Universal Pedal Adaptability: Hooks up seamlessly to OEM factory gas pedals or Lokar aftermarket billet foot pedal assemblies.

• American-Made Quality: Hand-assembled in the USA and backed by Lokar's Lifetime Warranty.
