    suspension lift question

    Cranking the keys will change your CV angles and tear up your front end quick fast and in a hurry. I've had two GMT400's with cranked keys and you will rapidly deteriorate your wheel bearing/hub assembly and ball joints. The ride is not terrible, but it's a tradeoff for doing more front end...

    6" RCX is on its way! help me decide 6"vs. 9" on 35s

    Last truck of mine had a 5" lift (3" BL, 2" blocks rear and 2" Keys front), and with 35's it looked just right. The BL isn't hurting anything, and who doesn't want more lift? I would keep the BL and go with 38's but if you don't want to regear 35 is the biggest you should go. A word of...

    Exhaust Build Help

    My old 95' Yukon GT (TBI) had factory manifolds and Y into a single 3" IN dual 2.5" out Flowmaster Super 44, sound was awesome and more low end. No cat work or anything. That being said, when I do the ex on my 00' OBS Tahoe, it'll be true 2.5" duals with cat delete and an x-pipe. Will be...

    5.7 Rod Knock? just bought it

    What really baffled me was that the oil seemed like a regular 10w and wasn't milky or didn't appear to have additional additives. Picked up a new alternator and cam so wrenching will soon begin.

    5.7 Rod Knock? just bought it

    Oil pressure isn't terrible. around 20 at idle, 40 normal driving and 55 if I romp on it (which sounds terrible with the rod knock so im not doing that anymore). Followed the generic rule of 10 PSI per 1000RPM so seemed fine to me. Gauge does bounce over bumps. previous owner and I signed a...

    5.7 Rod Knock? just bought it

    New to the forum with this truck, was on here with my old sierra, so :gmfs: Bought a 2000 Chevy Tahoe Z-71 (OBS) last week. Owned by an older guy who had it for 45K miles with no problems other than him doing a set of brakes, fuel pump, and intake gaskets (or so he said). When I test drove...
