80mph speedometer

[Thumper580]

I have a 2000 M1123 with the 4L80E four speed transmission. Is there anyway to use the 80mph speedometer from ECV's? Are there any other options for Speedo's that go above 60mph and still retain the original look. Thanks.

Thanks. I assume this simply screws into an existing port/connection on the 4L80E.

Yes, remove the mechanical connection and install new sender from kit. The kits are hard to find and pop up once in a while.

1k for a speedo kit, now that's surprising, I'll stay with my broken speedo and keep using my GPS

Or just buy a parts truck for all the stuff you need like I did. $3500 for this one I picked up.

There is another option but very rare to come up for sale as h1 had a mechanical 80mph speedometer.

There are also mechanical aftermarket speedos and 24v gps units.

That's actually a good plan, only thing is I don't know how many parts off of those can go on my m1123

I bought a field plug and was able to plug it in the booster socket on the passenger seat side and used a USB to charge my GPS unit

I use 3 3/8" (85mm) GPS speedos in both my HMMWVs, 80MPH in the 6.5L turbo/6L80 and 120MPH in the 6.6L.
They are very accurate as compared to my Nuvi
Kinda cool watching them climb to around 18MPH while sitting still on the deck of a ferry

I bought mine for the hardtop and slant back. Also be using the rear seat bases and seats. This is going on my m1152. The ac unit I may look into installing on my m1123.

The fan drive and gear box off these units go for a pretty penny so hopefully recoup some of the cost.

If you like to tinker like I do, pulling parts and listing on Facebook or epay is the way to go.
