Anytime. We can meet part way and you can take it for a spin and see how you like it.

I love it. It works great and I can cruise on the interstate at about 2600 rpm's without getting run over. I would do it again in a heartbeat. You will not be disappointed.

Truck1 is right on about the operating instructions. The install instructions are also somewhat vague. They leave a lot to be desired. Fortunately the install is fairly simple so the instructions not being the best doesn't hurt too bad. The customer service at GV is also very good so I would not...

My tire circumference is 33.1". The aluminum driveshaft reduces a lot of weight therefor it lessons the chance of vibrations considering the GV unit hangs off the back of the transfer case about 12" more than the original tail shaft alone. The aluminum one was probably about $50 more than...

We did not discuss what the 4x4 lockout circuit requires. I will play with it a little and see what happens. The maiden voyage to the office today via highway and running between 65 & 70mph was very nice. The tiny tach was reading anywhere from 2450 to 2650rpm's depending on speed. I'm...

That's terrible that work is getting in your way. :). I didn't track the total time of my install, but I would say 6-hours or less. I think I spent more time figuring out where to install the controller than nothing else. I ended up mounting it behind the glove box.

It turned out to be a bad ground and the 4x4 lockout tapped into the wrong wire. I ran a new wire for the ground when I got home from the ground block on the firewall to the inside the cab to the unit. It still was not working so I called GV and spoke with a guy named Mike. He was very helpful...

I was using a meter. I 'm getting 12.4volts to the controller using the controllers ground as my ground point. I was getting 11.3 volts at the blue wire on the manual/auto controller as per the troubleshooting guide. I'll play with the wiring some more tonight. The speedo was working although...

The driveshaft showed up Friday and I put it in yesterday. Took it for a 10-mile ride, but the unit isn't working. I ran thru the troubleshooting guide and everything appears to be hooked up correctly. The guide says the red light on the switch should illuminate when I turn the ignition key but...

I have mine already installed with the exception of the wiring. I purchased from a local dealer. I did pay sales tax, but was still less than the GV website price even with paying tax.

$50. I didn't know about the place in Lorton, but I would pay the shipping verses driving there anyway.

I couldn't find anyone local to make me one from scratch, so I went with someone I found online. Driveshaft Specialist of Texas in San Antonio. They were very helpful when I called and were familiar with what I was trying to do.

Good info truck 1. It's reassuring to hear from someone who has been running one. I only have a 1" zero rate in the back so my driveline angle won't be as steep as yours so I'm going to skip shimming the transfer case starting out. I also decided to go with an aluminum driveshaft to lower the...

Thanks. I did not weigh it, but I would guess about 25 or 30lbs. I pulled up and down on it and it mounts very solid. There is no movement between the crossbrace and the tail. I'm considering fabbing a crossbrace anyway just for peace of mind. Update: According to the GV website 32 to 46lbs. is...

I'm only guessing, but should be in the range of $250 to $300. I'll have to send them my slip yoke that came with the GV unit so they can properly balance the shaft. I called them today and I have to use a different template to measure on than the one I used. The guy was not a big fan of the...

GV unit installed I have about 90-minutes of time invested in this install so far. The GV unit is installed now and the speedo cable extension is installed. I'm going to go ahead and have a new driveshaft made instead of shortening my original. Will be ordering it today, so it could be a couple...

My unit arrived on Monday and I spent a couple hours last night reading the install instructions and starting the install. It is quite simple to install. I removed the rear driveshaft, then disconnected the speedo cable from the tail housing. Removed the 4-bolts holding the tail housing on and...

Still waiting on mine to be delivered, but it should be here soon. My understanding is you remove the current tail housing and install the GV unit which just bolts on in place of it. There is a wire harness to run to the cab with a controller that mounts to the dash. The unit can be turned on...

After a whole lot of research on here and deliberating I have decided to go with the Gear Vendors overdrive unit in my M1028. I figured I would post me reasoning in case others are having the same hangup. I had narrowed my decision down to a 700r4 swap and the GV. The 4L80 and 4L60 just turned...
