ak_petey 's blazer upgrade - stage 1

[ChevyKev]

A doubler will lower your gears, which will increase wheel spin when a lot of torque is needed to spin them, but not so much for overall speed (speed = wheel spin.) Lowering your gears takes away the top end, so you can turn the wheels slower while still in your higher torque range @ higher rpm's.

I think in this case you 5.13's are limiting you - Skitzo has 4.56's and my blazer has 4.88's. A lot of folks simply run the 4.10's and higher hp engines - you have the power to turn big tires with horsepower and 4.10's but don't reduce your overall tire speed/spin with too low of gears.

So at this point, doubler = no

New gears that are higher... probably not.

so I'd say build your engine for higher hp. That may be a bit tricky though as you'd also have to "tune" your computer, but I'm sure you could find some-way/someone to do that as well.
