Okay I guess I'm just dumb b/c I've had my truck almost 3 yrs and have never heard of this "power wire." Please someone inform me all about it. And as far as gears go, what gears are best and what kind of labor/cost would i be looking @? and how much would they help?

 

look on airram.com for the power wire. It has an explanation on there, but as far as performance goes I have heard that they are junk.

 

yea, i have one equipped on my truck...blows...just wastes gas. i have a thread on here with multiple 1/4mile runs...it does nothing.

 

as for gears, i have a 456posi. it cost $1100, but $500 of that was the posi. about $300 for the gear, and $300 for labor. that $300 for labor is why i opted for the posi...why not? if labor wasn't affected. i got a good us.gear too.

 

anyways, love the gears. i have the posi, which gives me twice the burnout friction, and i could still spin them A BIT. here's a vid (BEFORE HEADERS and muffler change)

what exactly is posi

 

limited slip differential. both wheels turn at all times...not just the right rear.

 

its a type of differential that sends the power to the wheel or wheels with the most traction, vs an open diffential which comes stock. an open differential sends power to the wheel that has the least traction. an open differential uses spider gears to achieve this, as a limited slip differential or posi as Eaton calls it uses clutches or gears.

 

oh and the power wire is supposed to advance the timing, but most people on here will tell you they are junk. Havent tried it myself, so I have no input on this

 

ok just didn't get the fancy abbreviation
