isn't there a top speed govenor on our Dakota's that the factory installed as a standard. I ask because I have had mine up to 105mph and it was still pulling. I could have sworn it was supposed to be around 98mph but I guess not.

All depends, Mine was set at 115 mph, some at 117 mph, and some at 98 mph. It all depends on things like steel or aluminum drive line, etc. etc. I had mine flashed to 135 mph.

Just hold the key in the start position and you
won't have a top spee limiter at all.
Dude, Yates-in-DE, have you ever had yours hit
the 135 speed limiter?
I doubt it but I'm just wondering.

I've run it setting on the 135 mph Speed Limiter many times for 20 and 30 mile Stretches (but of course that was while the truck and I was living in Germany). I will tell you this, after the flash about 129 mph is the trucks limit, so in order to go that fast I had to do some modifications, such as Cams, T-body, Exhaust, lowering, Clutch Fan Removal, Intense Z-tube, and others. It will now lay up on that 135 mph Limiter and hum like that all day long. Look at my Signature pick, that is a true pic of 120.

There is a sensor at the rear axle...if you disconnect that it'll get rid of the limiter but you won't have a speedo till you plug it back in. You may also throw a code but it'll bypass the speed governor

That's cool,
What kind of lowering setup do you have on the truck and how does it ride compared to stock?
I like it.
Also, are you running factory gears or did you get new ones and have your speedo sensor reset?
Thanks,
Matt

It is a BellTech 2x3 Drop, and it rides like a sports car. I had to trim the bump stops a bit. I have the factory 3.92's, but I have in a box sitting next to me here some 4.56's, and I'm waiting on the Powertrax to come in so I can change them out. and as long as you don't change the tire sizes the speedo will still be correct with a gear change.

Sweet,
I have a set of Belltech 2" blocks in the back and a set of 2" springtech's waiting for the front, but I could use another inch in the back. Yours looks sweet man. 4.56 is a low gear!!
I just changed tire sizes down to 245 50 16's, and that was a massive improvement over stock tires for the lower ratio. They're about 5" shorter than stock tires.
I have a Trac-Lok waiting to go in, but I'm not changing gears, so I won't have to mess with the pinion at all, just the ring backlash.
You'll need a tool to set the backlash and you can either spend $90 for the pair from Mopar, OR , you can have them made for about $8!!!!!
I found a set of nuts at NAPA with an exterior diameter of 1 7/16", and had the local steel fab shop weld these nuts onto a 3/4" solid square shaft 36" in length. The end of the shaft you're welding da' BIG NUT to has to be ground around the edges a little for the nut to slip over it.
The square shaft is perfect cuz you can grab it with a wrench. The only problem is that you have to put 70 lbs. of torque on the spanner nuts, but that's no problem, you can just use a half inch drive 3/4" crow's-foot to fit the shaft and set the tq. wrench to like 68 lbs. to compensate for the length the crow's foot adds.
I can email you some pics of the tool along with a few Great diff-install instructionals I found on the net if you'd like.
PS, could you give me some pointers on how you installed the front springs? I'd appreciate it!
let me know,
Later

There are custom PCM flashes possible for some years that can raise the limit high enough that you'll never run into it.
Lead, follow, or get out of the way
