    Rough Idle while Driving

    I have a 1992 K1500 with a 5.7. I recently preformed a tune up: plugs, wires, cap/rotor button, fuel filter, oil change and a PCV valve. While driving, between 1500-2000 RPM (in any gear) I feel a miss or a spudder. Any idea what it may be or where I can begin trouble shooting? I'm new to this...

    Advice needed on Receiver Hitches

    I have a 92 K1500 Heavy Half and I'm wanting to replace my old stock receiver with a new one. My question is do I need a Class 3 or Class 4? I rarely haul anything and I can't see hauling nothing heavier than a car (ever). What's the best choice for me? Thank you.

    Crank to Level...

    Hey everyone, I have a quick question about crank to level. Once you've done this, how much more could you go? Are the bolts for the torsion bars almost flush inside the crossmember? Reason I ask is with 265's, my front end measures 36.5 inches tall and i don't have much more bolt to turn and...

    Question about 285's

    I'm currently running a 265, but I'd like to move up to a 285. I don't want to lift my truck. Will I have to level it to clear or can it be left at stock height? Will I need to trim a bunch and what should I trim? Any advice or experiences would be greatly appreciated. Thanks!

So, he replaced the muffler with quietest one he had (MagnaFlow 13259, 3 inch in/out), cut my catalytic converter off, and dumped...
