Stainless Steel Throttle Return Springs

The Stainless Steel Throttle Return Springs from LOKAR (Model SRK-4002) deliver reliable, corrosion-resistant performance for custom automotive applications where original equipment springs fall short. These springs are engineered to restore smooth, consistent throttle response in street rods, classics, and performance vehicles that demand precision carburetor or fuel injection control. Supplied as a matched pair, they eliminate the guesswork of replacing worn or mismatched springs that cause sluggish or erratic idle recovery.

Crafted from premium stainless steel, these throttle return springs resist rust and oxidation in under-hood environments while maintaining consistent spring rate across temperature cycles. The natural finish preserves the material's inherent corrosion resistance without added coatings that can degrade under heat and vibration. Each spring is precision-wound to exacting tolerances, ensuring identical return force in both units—critical for balanced throttle closure and repeatable idle characteristics on carbureted and fuel-injected engines alike.

Custom fabricators, hot rod builders, and classic car enthusiasts benefit most from LOKAR's reputation for fitment accuracy and longevity. These springs accommodate most aftermarket throttle linkage assemblies and work seamlessly with LOKAR's complete line of stainless steel fuel system and carburetor components. Installation is straightforward on vehicles undergoing throttle cable or mechanical linkage upgrades, and the stainless construction ensures decades of trouble-free operation without seasonal corrosion concerns.
