    For the build I'm looking to strengthen some key points. my first priority being the transmission. ive read a few threads, but still. What can be done to bulk up the 4l60 to handle somewhere around 450-500hp? or would it be easier/cheaper to install a different transmission?

    Removing Exterior Molding

    So I have an 07 Envoy. And I hate the chrome molding on the doors, and the ENVOY lettering. Is there a way for me to remove it, so I can dip it, then put it back on? Or would it be easier to remove all together?

    Cam Shafts

    Hey guys, I was told by some of the people I work with that cam shafts could be a good mod and would be able to yield a decent result in power, especially when attached with a tune. Any truth to that? Also I've been unsuccessful in finding aftermarket cams with more lift and duration. Any ideas...

    Increase power

    Hey guys just wondering if there's any bolt on power for the 4200. I'm already working on a turbo kit but wondering if there is anything else out there. From what I've gathered online the aftermarket support for it is minimal but some people have found some things. Anything helps. Thanks

    Got a Super 44 Delta muffler. Basically going to chop out the old one and put it in with some adapters and clamps until I buy the whole system. Anyone know the size for the exhaust tubing? All I know is the muffler I got is 2.5 in and out. Thanks

    Envoy yoke to control arm bolts

    Hey guys I got a problem. I was putting in some new suspension in the front. My father in law was helping and he smacked out some bolts.

    Wheel Spacers

    Hey everyone, just had a quick question. I'm looking to widen my Envoys stance a little. Not a lot, just make them go past the fender (I've always thought the front wheels looked especially sunken in) Anyway, has anyone used wheel spacers and had any problems? Any specific brand? Thanks
