    Default How'd you guys upgrade your Suburban?

    So I've got my 1999 Suburban and want to start building it up and will hopefully get a 4 inch lift and new tires soon, but what has everybody here done to upgrade there's? I've also thought about fender flares, new wheels and stuff to improve performance. Open to any ideas or parts you've added to the exterior interior or anywhere else.

    I dropped in a K&N filter. I want to do a full cold-air intake, programmer and a custom dual exhaust (can't find a bolt-on dual kit for my 99 Burb) with headers. I want around 300 hp with decent economy. Mine is 2wd, so I'm going with a vintage street-rod look to mine. I am considering finding a similar 4wd to go with 33's or 35's. Thinking 3/4 ton for that because of the tire size. I'd like a diesel for that project I think, but a 454 would be good. I'm interested to hear what others say too, as I am not familiar with lifting Burbs...more of a Jeep guy, but I want something I can haul the kids around in too (all 5 of them!)

    Mines a 1996 4X4 1500, back in '96 we added a 6" ProComp lift (junk, IMO) and in '97 we removed the ProComp for a Rancho 6" which now has over 200,000 miles on it with no issues. We also installed Mickey Thompson Alcoa's 16x10 with BFG A/Ts or M/ts, K&N coldair, JBA headers, Magnaflow cat-back, 4.56 Precision Gears and a Hypertech programmer (just to adjust for the tires and gear change). I don't drive it much anymore as I usually now drive my Silverado or my wifes Trailblazer.

    I have a 4" lift, I believe it is a Rancho kit. Oversized tires but they aren't 33s I think. K&N air filter. These were put on the rig before I bought it.

    I recently added painless wiring digital power manager for dual battery control, and a Clifford 50.7x matrix alarm. Also following is going to be some stereo equipment.

    The other performance mod I added was the SSBC brakes dual piston front brake kit. I helped a bit in the braking department. I'm going to eventually swap the rear drums for rear discs, also thru SSBC.

    When my G80 blew up, I replaced it with an ARB locker.

    So the K&N air filter seems like a good thing for me to add, anyone have any advice on programmers? I know little about them or what companies sell them.

    @TurboChris: Just wondering where you got those headlights on the roof rack from, they look awesome!

    Can you give more details on the HID's? I have some APC projector lights, but they were terrible. I figure if I put HID's in the bulbs the projectors might work better. What kit did you use?

    Slightly off topic, but I have the APC housings, which in addition to being horrible don't mount the bulbs correctly so when I put in ebay HIDs I blinded everyone and took it all out.

    Back on topic, John I assume you have a 1/2 ton so some of my upgrades will be inapplicable, but just for grins I:
    lifted the front slightly with torsion keys
    lifted the rear slightly with RAS
    added Hummer H2 wheels and 265/70-17 All Terrain T/A KO tires
    Gibson cat back
    K & N intake
    other blah blah
    mirrors, door handles, flares, and D pillars painted body color

    You know, just the regular stuff. Much more too. Just not sure which direction you're headed.

    With my K-2500 I tow a small trailer filled with lots of toys, some I put on top with my four bar Yakima rack. With a 454 I don't lack for power, but I had to play with that, Hypertech, MSD, pillar gauges because the stock Vortec wasn't much in 1998.

    So what are you trying to do, other than lift, wheels, and tires?

    Besides that mostly looking to improve performance a bit if I can, but I also would eventually like to add extra lights, a grille guard and maybe a few other exterior mods. Thanks for everyones' advice!
