    Fix for floor mounted console cup holder

    I found a fix for the cup holder that goes in the center console for when the flimsy clips break that hold it together. I took an old soldering iron and plastic welded the two pieces together where they were touching. Hopefully it will hold for awhile until I can get one 3d printed.

    Fuel Gauge gone haywire

    I hope this is the right place to post this. I’ve noticed that the fuel gauge on my 98 K1500 just randomly stopped reading correctly, and it now does the hummingbird twitch. I’ve checked all the grounds on the tank from the sending unit, and I know that the float isn’t bent because I installed...

    Level Kit Done Right

    Good afternoon. I have been searching this forum for info on a proper level/lift kit maybe 2-2.5 inches. I am thinking about buying a set of Proryde or Readylift torsion keys both come with shock extenders, a set of either Skyjacker or RC ucas, and a 1.5 or 2.0 in block. I'm aware that...

    1.6 roller rockers with stock cam?

    One of my friends installed a set of 1.6 roller rockers on his LT1 with the stock cam and valve train. I figured since the L31 and the LT1 are very similar engines, I’m curious as to if the same upgrade could apply to an L31? I know that the Vortec heads can’t take a ton of lift, but the stock...

    RCD lift kit

    Wondering if anybody’s every ran a RCD lift and what their build quality is? I know they’re a knuckle lift and it’ll increase the front tract width 2 inches but I can get bora spacers to correct the rear.

    Zone Offroad 6 inch lift

    Any one ever ran a Zone lift kit? I’ve been doing some research on lift kits I don’t want to run a RC lift because a few of my friends have ran them and they had some trouble with them. The kit I really want is a Superlift 6 inch kit but they’ve been discontinued, BDS is another one I like but I...
