LiftMaster K99-VPV Viper Pivot Rod and E-Clips Kit
The LiftMaster K99-VPV is a replacement Viper pivot rod and e-clips kit used in select LiftMaster Viper traffic spike systems. The pivot rod acts as the rotational support point for the Viper spike mechanism, while the e-clips retain the assembly so the moving components stay aligned during operation.
This kit is a mechanical service part, not a complete traffic spike module. A worn, bent, corroded, or missing pivot rod can cause spike teeth to bind, sit unevenly, drag, or fail to reset correctly. Missing e-clips can allow unwanted movement in the assembly and may lead to additional wear or unsafe lane operation.
K99-VPV is commonly associated with Viper Series manual and automated traffic spike systems and LiftMaster perimeter access systems. Fitment should be verified by the original Viper module diagram because pivot rod dimensions and retaining hardware can vary between traffic spike families.

Technician Note
Replace missing e-clips and bent pivot rods before returning a spike lane to service. Binding or uneven spike movement may indicate additional damage to teeth, springs, plates, or the module body.
Before Ordering
- Confirm the traffic spike system is a LiftMaster Viper model
- Match the pivot rod kit to K99-VPV in the parts diagram
- Inspect spike teeth, spring hardware, top plate, bottom plate, and module body
- Verify the lane is safely blocked before any mechanical service is performed
Professional Advisory
Traffic spike systems should be serviced only when the lane is secured and the device cannot move unexpectedly. Automated systems should be handled by a qualified technician.
Product Questions & Answers
What does the K99-VPV kit include?
K99-VPV is listed as a Viper pivot rod and e-clips replacement kit. Other spike module components are separate unless specifically included by the seller.
Is this for manual or automated Viper systems?
It may be used with select Viper manual and automated traffic spike systems when the parts diagram calls for K99-VPV.
Will this fit Cobra or Stingray spike systems?
No confirmed universal fit should be assumed. Cobra, King Cobra, Stingray, and Viper systems use different service parts.
What problem can a worn pivot rod cause?
A worn or bent pivot rod can cause spike teeth to bind, sit unevenly, drag, or fail to move correctly.
Should springs and teeth be checked at the same time?
Yes. If the pivot rod or clips are damaged, the spike teeth, springs, bottom plate, top plate, and anchors should also be inspected.
