GEARS!! They make a huge difference. I can't believe the power I got back when I swapped in 4.56's.

If you have a 98 or later, gears won't shift the speedo back, but the true-speed will.

Gears will cost a couple hundred for the gears, and installation will total up to $1000-1300 or so, maybe less, maybe more.

Gear install takes hours to do right (if you've not done it before), I haven't done it, so I'm not much help there.

Truespeed install should take about 15 minutes, and cost $200 or so.

But, gears will do wonders for your power!

Well I just did my gears and the time it takes to install can vary quite a bit. If you are good at calculating pinion depth than it should go quick cause thats the real time consumer, taking the pinion and carrier in and out, putting evrything together doesn't take long.

On 98 and newer trucks, there isn't a speedo-gear in the t-case, like there was on older trucks.

Instead, they use the RWAL tone-ring attached to the ring-gear in the rear-differential.

So, as you change tire-size, the rpm of the axle changes vs. the speed you are going, which changes the speedo reading.

If you put in steeper gears, the tone-ring still spins at the same rpm it did before, so long as you haven't changed the size of the tires, the gears are "upstream" of the tone-ring, so they don't have an effect.

In the older trucks, the speedo/odo ran off the rpm of the rear driveshaft. So as you increased the size of your gears, the speedo goes up. So if you went with 10% taller tires, and 10% taller gears, the speedo would be about as accurate as from the factory (i.e., not).

But, with the new trucks, 10% taller tires + 10% taller gears means you're going 10% faster than the speedo says.
