The 20-37 carburetor throttle stud is a universal 7/32" linkage component designed for Holley carburetors and GM automatic transmission kickdown systems. Installed on the carburetor throttle arm, this throttle stud serves as the critical connection point between the throttle cable, throttle linkage, and transmission kickdown cable.
When the accelerator is pressed, the carburetor throttle lever stud allows the throttle plate to open smoothly while simultaneously triggering proper transmission downshifts under load. A worn or missing stud can cause poor throttle response, delayed acceleration, or loss of kickdown function. Replacing it with this precision-machined throttle lever stud kit restores correct throttle geometry and synchronized transmission performance.
 Constructed from corrosion-resistant stainless steel, this carburetor throttle cable stud is built to withstand engine heat, vibration, and long-term use. The complete kit includes the throttle stud, lock washer, nut, and retaining clip, providing everything needed for a secure, factory-style installation. Ideal for Holley 4150, 4160 carburetors, GM kickdown applications, performance builds, and classic vehicle restoration.
