A NEW limited slip differential option for Bugeyes and Spridgets!

April 10, 2026 by bugeyeguy

A limited slip differential is the single best modification you can make to your Sprite.

Every Spridget will spin the inside rear wheel on sharp turns. Watch any autocross, and the Sprites are squealing, failing to put the power to the road on both rear wheels. But with a limited slip, traction is dramatically increased. You’ll notice an immediate improvement in your acceleration out of turns, and also in the stability and smoothness of how you deliver power to the road. For years, we have offered a clutch-type limited slip, which is a great option, but can be noisy and temperamental. We now have a NEW option available that we are excited to offer!

This new, helical-type limited slip unit works just as well as a clutch-type limited slip differential, but without any of the noise and low-speed choppiness a clutch-type provides. Check out the video below to see one in action, and click on the photo above to order a fully rebuilt 3.9 differential with helical limited slip today! Each diff uses all-new parts, including a new 3.9 ring and pinion. Ready to bolt in and go!

Be sure to leave your gas pedal hanging!

March 13, 2026 by bugeyeguy

Your accelerator pedal is a vital link between your foot and your Bugeye. Without it, you quite literally aren’t going anywhere. And if it fails in use, you might actually find yourself accelerating out of control into whatever lies in front of you!

*An original Bugeye accelerator pedal used this system to connect the throttle rod to your foot; a hinged, long rectangular gas pedal and a ball-an-socket link attached to the rubber on the back of it.*

The original Bugeye accelerator pedal assembly relies on a hard rubber pedal into which a metal rod inserts. When the rubber socket dries out and/or cracks, the actuation rod can come unplugged while you are accelerating. I’ve had the original style pedal disconnect and jam the actuation rod at full throttle, so for your own safety (and the safety of your Bugeye), I would encourage everyone to upgrade to our hanging pedal as soon as possible.

*Over time, the rubber on the pedal holding the pedal link in place cracks and fails, detatching the accelerator pedal while driving and, in some cases, jamming the throttle wide open.*

In the video below, we explain the original Bugeye mechanism and the best way to improve it, our upgraded aluminum accelerator pedal!

We sell these aluminum accelerator pedal upgrades in our parts catalog. Should you also be interested in maintaining originality, we sell new original-style accelerator pedals, (as well as new throttle cables). If you insist on the original design, at least make sure your pedal rubber is supple and will hold onto the rest of the linkage without popping out, a new original pedal will reduce your liabilty.

Well…

February 27, 2026 by bugeyeguy

Don’t do this to your Bugeye Sprite.

*The* “well” *around this filler neck is not supposed to be there.*

In the “I’ve never seen this before” category, here’s a Bugeye rear deck that’s been damaged by someone who didn’t realize that the fuel neck to their tank could be modified to fit the body rather than making the body fit the tank. We’ve run into this before-old body damage to the back of a Bugeye and resultant body repair can make for a slightly fatter boot section at the filler neck. Because the filler neck is a fixed length on original and some replacement fuel tanks, it can be difficult or impossible to get the fuel cap onto the neck if your body is slightly taller at the location of the filler neck. This restorer chose to beat up the body rather than modify the filler neck and damaged the back deck of the car for no reason.

*A piece of rubber at the base of the filler neck allows for extension of the neck, meaning you can dial in the height for proper fitment of your fuel cap!*

The correct solution for a slightly pregnant rear deck is to cut the fuel filler neck and put in a rubber hose with clamps to extend the neck above your existing body and thereby make your filler neck adjustable in height.

*Our fuel tank kit comes with a detachable filler neck, so no cutting or rear deck mutilation necessary to achieve proper fit! Click the photo to order!*

We sell a fuel tank kit with a removable neck and you can set the height of the neck to your specifications regardless of any body damage that may have been built into your car before you bought it. You should never have to damage the body of your Sprite to get something to fit… call us if you have a problem that makes it looks like that might be needed —we’ll help you find a workaround.

*A fixed-neck tank can result in a cap that is too close to the filler neck, which can close your tank vent and affect how your Bugeye runs!*

*This is what your filler neck should look like when the fuel cap is attached, with a small gap between the bottom of the cap and the top of the filler neck gasket.*

Another important issue here is that sometimes the fuel cap is way too tight against the body rubber gasket, which blocks the vent in the cap, creating a fuel delivery issue. So make sure you have at least an eighth of an inch gap between your cap and the rubber grommet that goes in the back deck, so that your fuel tank can vent properly, otherwise your engine can die if the tank doesn’t breathe. If your cap is too close to the grommet, you may need to cut your filler neck, just like the above restorer should have. We have all of the parts and tools needed for this job in our parts catalog!

High voltage

February 20, 2026 by bugeyeguy

We are constantly improving our processes here at Bugeyeguys, always looking for ways to make each Bugeye the best that it can be. This week, we’ve decided to install a new system in every car that departs our building from this point onward, to better enable our clients to quickly understand the health of their charging system. And we want to encourage you to add this tool to your Spridget, as well!

Periodically, we have clients encounter charging system problems, and it is very difficult to try and help them over the phone diagnose whether or not their cars are charging properly. But now we have a new system which represents the simplest way to immediately answer the question, “Is your car charging?” These plug-in cigarette lighter volt meters are a nifty way to immediately know and understand your charging system health, and they’re inexpensive to buy, so we encourage you to add one today! Simply rear the voltage with the engine off and start the car to verify if the voltage increases, an indication of good charging system health.

You can click the links below if you want to see them in our product catalog and order your own . We offer two types; if you already have a cigarette lighter in your car, you can simply plug-in this cigarette lighter voltmeter and you’ll end up with two USB ports as well to charge your phone accordingly. If you don’t yet have a cigarette lighter socket in your Bugeye, our hard-wired version would be the next best thing for you. These can be hardwired into your car without much difficulty, and can be placed anywhere under the dash, should you not want to cut a hole in your dashboard. As a reminder, these are for negative ground cars only!

*Bugeye USB port (hard-wired version)*. Volts show in the center of the plug once powered up.

Axle ouchie

January 9, 2026 by bugeyeguy

The unassuming pile of random metal chunks shown above may look pretty innocent to most, but they are the remnants of a crippling failure that will ground any Bugeye in an instant.

The pictures shown here are just a few examples we have encountered over the years involving axle shaft failures on Bugeye Sprites. This is a failure that is not uncommon in Spridget circles; often (but not always), overly aggressive acceleration, deceleration, clutch dumping, burnout attempts, or other automotive hijinks are the culprit.

But many of our more recent examples have come under completely normal driving conditions. For example, the axle bits in the top picture were removed from Jose’s Bugeye over the holidays in our shop after he heard a pop and lost all forward motion while driving in New York City. He originally thought he had a clutch issue, but once we learned more, it became apparent a broken axle shaft was to blame.

We offer in our catalog both new and used axle shaft options, should you encounter a broken one in your Bugeye. Click the links below for more information, or click here for our complete catalog!
