JEGS throttle linkage tube kits are designed for dual four barrel carb applications and utilize aircraft grade parts for precise operation without the slip or flex common to other systems. JEGS throttle linkage tube kits feature a stainless main shaft with 36-spline ends, anodized billet aluminum arms, and mounting brackets. Each and every moving part rides with either needle bearings or a spherical rod end which eliminates deflection and binding. Right and left hand threaded linkage rods allow for fine incremental adjustment without disassembly.
