Liftmaster K99-COBSM-T18CR, 18" TEETH SECTION, COBRA, KING COBRA CR
The LiftMaster K99-COBSM-T18CR is an 18 inch teeth section for Cobra and King Cobra CR traffic spike systems. The teeth section is one of the most visible and hardest-working pieces in the lane because it directly contacts wrong-way tires and must return to position with the rest of the spike assembly. This part is commonly replaced when individual teeth are damaged, the section is bent, return hardware is worn, or impact has left the lane-control system uneven. It must be matched to the Cobra/King Cobra CR layout and not substituted with a different teeth-section style.
Compatible With
- LiftMaster Cobra CR traffic spike systems using the 18 inch teeth section
- LiftMaster King Cobra CR traffic spike systems using the 18 inch teeth section
- Model references 12300 and 12360 when confirmed by parts diagram
- Surface-mount Cobra/King Cobra CR systems using matching teeth section hardware

Technician Note
For K99-COBSM-T18CR, the safest match is the original part number and the specific LiftMaster traffic-control parts diagram. Do not rely on appearance alone, especially with Cobra, King Cobra, Stingray, Viper, and CR plate variations.
Before Ordering
- Match the original part number on the removed part or parts list
- Confirm the traffic spike family: Cobra, King Cobra, Stingray, Viper, Enforcer, or other LiftMaster system
- Check plate thickness, tooth count, CR designation, shaft length, bearing size, or sign type when applicable
- Inspect surrounding hardware for wear so the new part is not installed against damaged components
- Do not substitute a similar-looking part unless the manufacturer parts diagram supports it
Important Ordering Warnings
- Similar LiftMaster traffic spike parts may not be interchangeable
- CR, surface-mount, concealed, in-ground, and standard versions may use different hardware
- Traffic lanes should be blocked and secured before service
- Warning signs and safety instructions should remain visible and intact
Professional Advisory
Traffic spike systems can create severe tire damage and should be serviced only with the lane secured, the system locked out where applicable, and all warning signs and traffic-control procedures in place. Do not modify the system or remove required warning devices.
