LiftMaster K177-0237 Cobra Traffic Spike Springs - Qty 4
The K177-0237 kit includes four springs for LiftMaster Cobra and King Cobra traffic spike systems. These springs are part of the mechanical return system that helps the spike teeth move back to the correct position after vehicle passage. In parking, gated community, and commercial traffic control applications, weak or broken springs can cause spikes to stay low, return slowly, or sit unevenly.
Traffic spike systems are safety-sensitive vehicle control devices. Springs should be matched to the correct spike system, and damaged housings, pivots, rods, and related hardware should be inspected before replacing only the springs. If the spike unit has been hit by a vehicle or has heavy corrosion, spring replacement alone may not restore reliable operation.

Technician Note
When replacing spike springs, inspect the hinge points, pivot rods, fasteners, and spike teeth. A bent or corroded spike assembly can overload new springs and cause uneven return action.

Professional Advisory
Traffic spike systems can damage vehicles or injure people if serviced incorrectly. Secure the work area, follow the manufacturer service instructions, and use a qualified technician for repairs involving traffic control equipment or moving spike assemblies.

K177-0237 is commonly listed as a set of four replacement springs for Cobra traffic spike systems.
Does this fit King Cobra systems?
Yes, compatibility references include various LiftMaster Cobra and King Cobra traffic spike systems, but the exact parts diagram should be checked.
Why do traffic spike springs fail?
Springs can fatigue from repeated cycling, corrosion, road debris, impact damage, or binding hardware.
Will new springs fix spikes that stay down?
They may, but spikes that stay down can also be caused by bent teeth, damaged pivots, debris, or a distorted housing.
