LiftMaster K99-VIP-BP Viper Surface Mount Bottom Plate
The LiftMaster K99-VIP-BP is a Viper surface-mount bottom plate used in select LiftMaster Viper traffic spike systems. The bottom plate is a structural service component that supports the spike module assembly and helps maintain the proper base for the moving spike or directional enforcement components.
This part is used on Viper SM systems, not Cobra, King Cobra, Stingray, or in-ground assemblies unless a parts diagram specifically calls for the same part number. Bottom plates can look similar across traffic spike product families, but hole pattern, module length, fastener layout, and surface-mount profile may differ.
Use this part when the original Viper surface-mount bottom plate is bent, corroded, damaged by vehicle impact, or removed during traffic lane service. Because traffic spike systems are safety-critical access-control devices, the complete module should be inspected before replacing only one structural plate.

Technician Note
This is a Viper surface-mount component. Similar LiftMaster traffic spike bottom plates are product-family specific and should not be interchanged by appearance alone.
Before Ordering
- Confirm the system is a Viper surface-mount traffic spike system
- Match the original bottom plate and parts diagram to K99-VIP-BP
- Inspect pivot rods, springs, teeth, covers, and mounting hardware for related damage
- Confirm the traffic lane surface is still flat and suitable for remounting
Professional Advisory
Traffic spike systems can damage tires and create serious site hazards if repaired incorrectly. Structural repairs should be handled by a qualified access-control or traffic-control technician.
Product Questions & Answers
Is K99-VIP-BP used on all LiftMaster traffic spike systems?
No. K99-VIP-BP is associated with Viper surface-mount traffic spike systems and should not be assumed to fit Cobra, King Cobra, Stingray, or in-ground systems.
Does this include the spike teeth?
No. This is the bottom plate only. Teeth, springs, rods, covers, and mounting hardware should be ordered separately if needed.
When is a bottom plate normally replaced?
It is commonly replaced after impact damage, corrosion, distorted mounting points, or lane service that damages the original plate.
Can this be used on an in-ground spike system?
Not unless the manufacturer parts diagram specifically calls for K99-VIP-BP. In-ground systems use different base and mounting components.
What else should be checked when replacing it?
Inspect the full spike module, pivot rod, e-clips, teeth, springs, top plate, anchors, and road surface before returning the lane to service.
