Is the throttle on your classic GM truck or SUV feeling lazy or not snapping back like it should? These two throttle return springs are a simple, vital fix! They're brand new and designed for GM and GMC vehicles like the C/K series pickups (think Chevy Silverado/GMC Sierra), Blazers, S10s, C10s, and similar models with carbureted engines. The throttle return spring is a small but crucial safety component – it ensures the throttle plate closes when you take your foot off the gas pedal. A worn or broken spring can lead to a stuck throttle, which is dangerous. This pack gives you TWO springs, so you have a spare or can do a redundant dual-spring setup for extra safety (a common hot rod trick). The brand isn't specified, but they're made to do the job. Installation is usually straightforward, involving hooking one end to the carburetor linkage and the other to a fixed point on the engine or firewall. If you're working on an older GM truck's engine bay, checking and replacing these springs is smart, basic maintenance. Keep your vintage ride running safely and responsively with this affordable pair of essential springs.
