I just bought a 07 Tahoe. Should I buy a 4" drop hitch?

All of you who have the non variable valve timming and displacemen on demand tahoes that need power, is it a z71/ltz truck? D me a favor and look in the glove box, there is a white data plate/sticker on the glovebox door. What your looking for is the code g80 and tell me what the gt_ code is. G80 is gms factory locking diff. And any gt codei the axle gear ratio. That will gieyou a beter idea of what yur working with.

Also, if you want more pulling power, I know this sounds crazy, but supercharge it. Jut hear me out. The magnuson tvs 1900 is what the cts-v and vette' zr1 have on them. Its the most efficent system on the market. You'll lose about 1mpg all round, so long as you keep your foot out of it. And with a 3.42 gear and a 4 spd trans, you will have the power to pull hills with out downshifting AND with out haveing to sacrifise any mph (as you would going from a 3.42 out to a 3.73 or 4.10).

I know a lot of guys who have done this instead of changing gears and they love it. It is. 10 to 12 hour job, and is alittle more $$$, but it is more caust effective over the long haul.

The guys with displacement on demand, sorry but your screwed. Your better off getting rid of that system. But he only way to do that with out swapping the motor is to change out the cam andother valve train componets and the soft ware in the computer to totaly delete it

Axle RPO codes

GT4 -- AXLE REAR, 3.73 RATIO
GT5 -- AXLE REAR, 4.10 RATIO
GU4 -- AXLE REAR, 3.08 RATIO
GU5 -- AXLE REAR, 3.23 RATIO
GU6 -- AXLE REAR, 3.42 RATIO
G80 -- AXLE REAR, Factory Locker

Thanks man. That deff. Helps

HOOK IT UP AND GO FISHING.

Tamale lives in a whole different world from us northerners and easterners. Try towing on 281 between Evant and Lampasas and you will be downshifting. Depending on the vehicle you might be downshifting with nothing behind you. Our hills are just bumps in the road compared to down there.
