Gear Vendors (is it time) ?????

Well with diesel at $5 a gallon i would say that a $2-$2500 gear vendor would pay for itself pretty fast but which ones do you guys run.

Re: Gear Vendors (is it time) ?????

The way i see it, it would take roughly 85 tanks of fuel for a $3k unit to pay for itself. 1 fill up per week on average means just over a year and a half to pay for it. I am really contemplating this because i dont see diesel ever going back lower than $4.50 a gallon.

Re: Gear Vendors (is it time) ?????

I fully intend to put one on (over top of my 3.08s) in a few weeks.

I'm planning to go with the GV. It has a bigger overdrive than the US Gear - 0.72 for GV, 0.8 for US gear. I had a GV on another truck and it worked out well.

Overdrives cost about $3500 installed, but if you are driving the miles it will indeed pay for itself. The fact it quiets the truck is worth somethong by itself.

Re: Gear Vendors (is it time) ?????

I thought I remembered somebody warning that if you did something like this that the engine rpm drop would be hard on an automatic transmission. I wouldn't take my word for it. I'll be the first to admit that what I don't know is a lot.

Without doing the math, I would imagine that by doing this we would end up in the range that Dave is at with just his 3.08 gears. What kind of a ratio will Dave end up with?

I have read Dave concerns with Automatic trannies. With low RPM an big loads there is the possibility of cooking the tranny. Automatic trannies need the RPM to keep the Fluid flowing right...

Re: Gear Vendors (is it time) ?????

I think Dave said his last truck with an auto ate trannys with the GV. Same thing with running 3.08 gears with an auto. It will always be downshifting to bring RPM back up & that's going to put wear on your tranny. On top of that burn up more fuel with all the upshifts & downshifts & kinda defeat the point of having it.

I think installing a GV in an auto tranny with 4.10 or even 3.73 gears for running unloaded or a load in the bed down the highway would be the way to go. You can always turn is off & not use it if your pulling a trailer & need that extra grunt right?

Re: Gear Vendors (is it time) ?????

I was wondering if that would make any difference on a lifted truck?? You would gear the truck to match stock the best you can...then add the gearvendors?? Would you see any difference??

Wouldn't that also depend on the gearing & size of the tires that your running? Like a truck running 4.56 with 37" tires might like having a second OD when your just crusing down the highway vrs a truck with 3.73 & 37s might lower rpms too much.
That make sense?
