    L31 Vortec 5.7 Heads/Cam advice for my 1999 K2500 Suburban

    Sorry for the delay in answering, my life has been a bit hectic lately. Well, I still have the truck. It still has a 350 and a 4L80 that needs a rebuild. I bought a 2010 Chevy Colorado with a 3.7L inline-5 (yeah.. I know) with super low miles from an insurance auction, and retired my daily...

    Trakmotive extended travel CV Axles

    I've never seen them in real life but they seem like a cool idea. Napa sells what I can only imagine are the exact same axles rebranded too (but they're never in stock around here). Might be worth checking out, napa used to have great warranties on wear parts (like hub bearings & CV axles)...

    2wd frame vs 4wd frame?

    Take a look at some SAS threads here and on Pirate4x4, I think Offroad Design has some good pics on their website showing how to put their SAS kit on a 4x2. If I recall correctly, the only difference is that in the last two inches or so, the 4x2 frame has a rounded blunt end to it, while the 4x4...

    Lower Control Arms Help

    Looks great. I see your fancy upper control arm. Are you cranked quite a bit? Did you drop the front diff down a bit? Angles look fine. I want to do the same thing to mine witj a 2003+ full soze van spindle since the mounting point for the upper ball joint is about 1.5" higher, should allow for...

    Lower Control Arms Help

    The lower control arm bushings I use for my '99 8-lug 2500 with forged lowers were these 2: AC DELCO 45G9213 GM 89033036 AC DELCO 45G11076 GM 88996751 They had "Made In Mexico" moulded in the same place as the originals that came out.

    AFM DELETE PROBLEMS

    Did anything have AFM in 2005? I thought that was an '07+ thing? AFM in a 2005 sounds like the first problem..

    Lower Control Arms Help

    The parts houses show different part numbers for the stamped vs forged arms. I don't have any stamped arms available to tell what the difference is.

    Lower Control Arms Help

    Are the Hummer H2 bushings somehow different from (superior to?) the bushings used on other 3/4 ton fully forged lower control arms? Or are they just a convenient vehicle to look up for the correct part? (I'm assuming H2's never had the stamped arms?) Curious for myself here, but I think it'd...

    Lower Control Arms Help

    C1500 means 2 wheel drive. Those have a pad for a coil spring that goes where the front axle would go, and they don't have a socket for the torsion bar.

    Lower Control Arms Help

    I have a '99 K2500 all forged LCA on my bench right now. I can provide measurements if that would help.

    96 Suburban ABS Module - unfixable and unsure what to do

    I don't know if they actually check ABS functionality on 90's GM products in Cali through the data link connector (OBDII port). I kind of doubt it because it would probably cost them a fair bit to be able to. The good thing about the Vortec 96-00 trucks is that the ABS light is fed directly...

    Which oil pan for Dart SHP 1-piece seal block?

    Hey guys, Hypothetical question. If I already owned a 3.75" stroke crank for a 1-piece rear seal engine (86+) and I had the chance to buy a Dart SHP 1-piece rear seal block - do you guys know what oil pan would work for a K2500 that previously had a Vortec engine? This may be a stupid question...

    Can they turn any better?

    There were also changes to the control arms that enabled a tighter turning radius (at least for the 2500 series). Initially these trucks had stamped steel lower control arms that were welded together. Sometime around 97 they switched to forged ones that allow the knuckles to turn more before...

    no cheap lockers for 6 lug open diff?

    I don't have access to a parts breakdown page at the moment, but I can tell you that if I go on Rockauto and search for a 1996 Cadillac Fleetwood with a 5.7 V8, under Drivetrain, Differential Cover - they list the GM OEM 9.5sf cover (after all the normal 10-bolt 8.5 covers) as a possible...
