    2003 Tahoe/4.56 gears on 33s?

    The H3 Alpha edition came with 4.10 gears from the factory not 4.56 so maybe the person you bought it from installed 4.56 gears. But how was it? did it rev too high at highway speeds?

    2003 Tahoe/4.56 gears on 33s?

    Hello everyone, I was wondering if anyone out there has 4.56 gears with 33s? I’m highly considering it but would love to hear feedback from those who have had or currently have this set up. I off road often and I rarely tow. I do 15 mile drive to work, all highway. Please and thank you...

    2.5 inch vs 3 inch muffler

    Hello everyone, I was curious as to what everyone's thoughts were on wether to put a 2.5 inch in/out muffler vs a 3 inch in/out muffler on a stock Chevy tahoe 5.3l. I recently got a Carven TR 3" in/out muffler installed and many people were telling me I should have gone with a 2.5" in/out...

    new Carven TR muffler/Performance Issues

    according to the muffler shop it became more noticable with the new muffler because of the change in flow. Going from a really big 22" muffler to a small 14" muffler caused a change in flow especially in the low rpm range. Now that the catalytic converter was changed it feels like a new car...

    new Carven TR muffler/Performance Issues

    Well the car was running bad since I got the muffler installed. I got the plugs and wires done the next day because I thought maybe the plugs and wires were old, but it still drove the same even after.

    Yes they welded the muffler on. I will check under there and see if they might have burnt any wires or anything. I am also thinking the steel wheels are making it slouchy too. They are 42 pounds each according to Pro Comp. Thats HEAVY.
