Should I install a Vertical Lambo Door kit myself or use professional installation?

DIY installation is possible for experienced installers, but professional installation is recommended for best results. Proper alignment, clearances, and hinge adjustments are critical for OEM level door gaps and long term reliability. For the best experience, choose installation by the manufacturer at our Lake Elsinore, CA facility.

What is the normal installation process?
  1. Disconnect the battery.
  2. Remove the fender.
  3. Remove the door catch if equipped.
  4. Get more wire slack if needed. Remove the door panel or kick plate if required. Do not cut factory wires unless you have no other choice.
  5. Use 2 inch painters tape to mark the factory door location on the vertical and horizontal planes. Also measure the distance between the apron and the front edge of the door by the top and bottom hinge.
  6. Close the door and use 2 inch painters tape to secure the door to the body.
  7. Install the new kit. Make sure you have a flat mounting surface. If needed, modify the apron for proper fit.
  8. Make fine tuning adjustments. Grease all pivot points. Install the shock. Do not use tools on the body or shaft of the shock.
  9. Modify the factory wire loom. Cut the factory wire boot in half and add wire loom to protect exposed wires.
  10. Cut the inner lip of the fender only enough for the swing arm to move freely, smooth the cut, then use touch up paint to protect exposed material.
  11. Close the door and reinstall the fender after alignment is correct and all hardware is tightened with threadlocker.

What are the most important tech tips for a clean installation?

Do not take the door off during installation. Make sure the mounting surface is as flat as possible. Set the hinge allen screw adjustments correctly. Most vehicles require trimming or rolling the inner fender lip just enough so the swing arm moves freely. Always protect and extend the factory wiring loom as needed.

Vertical Doors basics

What are Lambo Doors?

Lambo doors get their name from Lamborghini. In the early 2000s, Vertical Doors, Inc. introduced its Vertical Doors Conversion Kit. Many people call them Lambo Doors, while others call them Vertical Doors. You may also hear scissor doors, wing doors, VDC kits, butterfly doors, or Lamborghini doors.

What is the difference between a Lambo Door and a ZLR Door Conversion Kit?

The Vertical Lambo Door kit opens on the horizontal plane first, then on the vertical plane. The ZLR Door Conversion opens in a single motion diagonally outward similar to the Mercedes Benz SLR McLaren style.

Does the VDC kit replace my doors?

No. It only replaces your door hinges. You keep your original doors.

How does the VDC kit function?

Open the door about 12 to 18 inches like normal. From there the door stops and does not open horizontally any further. Then lift the door vertically until it reaches its designed stop so you can get in and out of the vehicle.

Shocks

Why Can't I compress the Shocks with my hands?

The shocks are highly pressurized and will not compress by hand. Once installed, the weight of the door compresses the shock as designed. Each shock is pressurized to support the stock door weight for that specific vehicle.

Quality and safety

How does Vertical Doors, Inc. Compare to Imported Lambo Door kits?

Vertical Doors, Inc. uses stronger steel, heat treats pivot and strike points, uses Germany made shocks, provides detailed instructions for many vehicles, offers free tech support, and manufactures USA made and USA patented hinge systems.

How strong are the Vertical Lambo Door Hinges?

They are very strong. Real world crash examples have shown the hinge system can remain functional even when surrounding body panels have significant damage.

Adjustments

How do I adjust the Lambo Door Hinge

The hinge system has adjustments on both the vertical and horizontal planes. Use our Tech Tips resource for guidance on fitment, alignment, and smooth operation: VDI Tech Tips.

Replacement parts

Can I purchase Vertical Doors, Inc., shop replacements for my car?

Replacement shocks are for Vertical Doors, Inc. bolt on kits only. Please provide:

  1. Proof of purchase (invoice or pictures of the hinge and shock).
  2. Year.
  3. Make.
  4. Model.
  5. 2 door or 4 door.
  6. Any door modifications (speakers, molding, etc.).
  7. Driver side or passenger side.
  8. Measurements of the shock body.

Sponsorship

Does Vertical Doors, Inc., do sponsorships?

Yes, sponsorship requires a formal proposal by email. Include:

  • An image of your vehicle
  • Your social media presence
  • Mod list
  • Shows and events attended
  • Awards earned
  • Future show schedule
  • Media coverage

If approved, you may receive up to 50 percent off retail price of the kit, not including shipping. Send your proposal to sales@verticaldoors.com.

Maintenance

What kind of grease do I use?

Use a high quality automotive or marine grease designed for a grease gun. Lucas Heavy Duty Grease or Green Grease are good options. Inject grease into the zerk fittings on the hinge and the shock end fitting. Under normal use, lubricate about once every 1 to 2 years, and more often if the vehicle spends a lot of time outside.

What kind of maintenance is required on these kits?

Grease hinge zerk fittings as recommended. If fittings are difficult to access, use WD 40 or a similar spray lubricant to coat the pivot area. Lubricate the shock bearing as needed. Start with a cleaner lubricant like WD 40 to flush debris, then follow with white lithium grease for longer lasting lubrication.

Finish

Do the doors come painted?

We sell a conversion kit that includes specialized hinges and hardware to convert your existing doors to a vertical style. All hinges come painted or powder coated black.

I was having trouble with my C8 Door after a terrible attempt at install by another company (Eikon Motorsports). I called Vertical Doors and Danny was able to be a hugeeeee help. He got me in right away, told me exactly what the problem was, knowledgeable, extremely responsive, and communicated with me the whole way through. I cant say enough of the team there. I wish I would have come to them in the first place.

These guys are great. They fixed my busted-up knockoff kit that I had done elsewhere with one of their premium ones, and even identified and corrected some other issues the previous installers caused.

Bottom line, they are passionate about what they do, exceptionally good at it, and top it all off with amazing customer service and a friendly attitude.
