I’m deciding if I should add a coil spacer on my 2wd Silverado. I’m torn between a 2”, 2.5”, or 3”. Ideally I would like to run a 3” but I’ve heard I would need new control arms with a 3” but I would like some other opinions. If so, would is the biggest I could do without needing to replace any parts? Also I plan on adding some rear lift blocks and not sure what minimum size block would I need for it to sit level?
Hello, I looked 2008 GMC Sierra 1500 that I was interested in purchasing with the 5.3L V8 has 174,000 miles. Truck runs rough at idle, rpms are fluctuating. Check engine light is on with codes P0300 and P0301. Can’t troubleshoot the problem. Coils, spark plugs, spark plug wires, new O2 sensors, new catalytic converters. Guy says that rockers all move so it isn’t Active Fuel Management lifters and he says 150 psi of compression across all 8 cylinders. Truck was at dealership, dealership says problem with cylinder numbers 1 and 8 the P0301 explains problem with cylinder 1 but why isn’t code P0308 being thrown? What else could be the problem?
hello everyone im a long time lurker, ive been trying to find answer but cant find a clear one or even remotely, the question is surely beaten to death but here we go.
I have a 2017 silverado LT, i already have 285r70/17 M/T im looking to buy newer rims the one i like have a 10 mm offset, im looking for a more aggressive stance i was wondering if i put 1.5 inchs spacer or 1.75" will the whole thing rub everywhere i have a 3 inchs level kit in front and 1 inch in back.
Also would it be preferable to have an negative offset wheel instead of spacers ?

Ok, so here's the deal my truck keeps throwing the P0300 code (multiple cylinder misfire) and we can't figure out what is wrong with it. We've changed the knock sensor, the crank position sensor, changed the whole distributor to a MSD billet distributor (street fire model), changed plugs and wires, changed the coil. None of them have changed the fact that it keeps throwing this code. I also have the upgraded acdelco Spyder injection system. The motor is a freshly built 383 stroker built by a reputable engine builder when we first started the truck it ran like shit so we sent the computer to blackbear and had it tuned to the motors specs. When we got the tuned computer it in the truck it ran a hell of a lot better but it still keeps throwing this code. If anyone can point me in the direction of what could possibly be wrong or point me towards a good tech for these truck it would be greatly appreciated.
