    OEM Dash Switches for ARB Compressor and Lockers

    I'm currently installing an ARB compressor and lockers in my 98 K2500 and really wanted everything to look as factory as possible. I figured I'd share how I put together a custom harness and switch combo. The top position of the triple switch retainer needs a little trimming with a Dremel to fit...

    Code/Name for the 1995+ DARK Grey Dash Bezel Accent Color

    I'm struggling to locate the color code or name of the dark grey accent color that surrounds that the gauges, HVAC, radio, etc. on ALL 95+ GMT400 dashes. I'd like to customize some switches to the right of the gauge cluster and paint them to match. Just to be clear, I'm referring to the the dark...

    Fuel Gauge Wiring with PCM Delete

    I’m trying to delete the PCM on my 1998 K2500 Cummins swap and rewire my factory fuel gauge. Truck was originally a gasser with a single fuel tank. Pin 13 on PCM connector C3 (grey/clear) is “Fuel Level Module” coming in from the in-tank sender and pin 9 on PCM connector C1 (blue) is “Fuel...

    Adjustable proportioning valve for ABS Delete

    Just to be clear. My original post was more of a question of curiosity than of concern for needing to fix the brake system. I’ve put 2000 miles on the system at this point and the truck stops great in all conditions. My ABS module could very likely have been malfunctioning, but this is...

    Adjustable proportioning valve for ABS Delete

    Are you suggesting that the 3/16 braided line to the 1/4 rear hardline is what is causing the rears to lock up? Seems like that would be restrict flow and if anything, weaken brake pressure to the rear. I’m positive the radii on the braided line bends are fine. That’s just perspective from the...

    Adjustable proportioning valve for ABS Delete

    Thanks man. My truck was originally a 5.7 auto but that pic is from the middle of my Cummins/NV4500/NP205 swap. All the details about that can be seen here: https://www.4btswaps.com/threads/crusty-the-bomber-6bt-nv4500-np205-swapping-a-gmt400-k2500.109723/#post-1073125

    Adjustable proportioning valve for ABS Delete

    I don’t remember the part number off hand but it was just a basic black Wilwood proportioning valve. I also used a Wilwood 10lb residual valve on the line to the rear axle.

    Adjustable proportioning valve for ABS Delete

    Flairing stainless hardline for first time ever with the OTC flair kit I bought was a complete failure... Every line leaked. There is definitely a learning curve to it.

    Adjustable proportioning valve for ABS Delete

    The loops are engineered for a reason but it’s not for cooling. It is to accommodate the body of the truck flexing independently from the chassis. I went with braided lines after failing to properly flair stainless hard lines...

    K2500 Lower Control Arm Bolt Removal

    This is a K2500 and the bolts contact the main axle shaft flanges, not the CV shafts. I trimmed one edge (about a 1/4”) off the bolts for them to slide out. They could be installed “backwards” and still clear everything but since the new “slim head” design fits easily I’m gonna reuse them in the...

    K2500 Lower Control Arm Bolt Removal

    Jesus Christ... My Cummins swap doesn’t leave enough clearance above the front diff to push the axle up out of the way. Removing the front axle for this seems like an outrageous servicing requirement. Now I’m thinking about just reusing my new 5 sided bolts...

    K2500 Lower Control Arm Bolt Removal

    I've asked two mechanical engineers in the automotive R&D field about installing the new bolts "backwards" and neither could foresee any issues with bolt or bushing integrity with this particular application. I'm trying to wrap my head around why they would be installed that way from the...

    K2500 Lower Control Arm Bolt Removal

    I’m in the middle of rebuilding my entire front end. I have forged LCAs. The rearward bolt of both LCAs has the head facing forward and cannot be removed without contacting the axle shaft flanges. Is removing the front axle a required step for removing the LCAs or were my bolts installed...

    who are the go to steering/suspension parts now?

    I’m in the middle of replacing all control arm bushings, upper and lower ball joints, inner and outer tie rods, pitman arm, idler arm, and idler bracket. All ACDelco Professional line. It’s a mix of made in USA, Mexico, and Taiwan. Everything seems nice and tight though and a better fit and...

    Adjustable proportioning valve for ABS Delete

    Thank you for the advice but I’ve already tested it multiple times it light and heavy rain and this current set up is far better and more stable in every condition than the janky ABS that was on it before. I own multiple early 2000’s sports cars and I know how a good, OEM ABS system from the...

    Regular Gmt400 master. I don’t detect and leaks and I’m pretty sure everything was bled properly. The pedal is nice and firm.

    Adjustable proportioning valve for ABS Delete

    So I’ve deleted my ABS system and I’m trying to dial in my new proportioning valve. My new brake system consists of the original vacuum booster and master cylinder with 3/16 braided stainless lines to a Wilwood adjustable p-valve. Front brakes are braided stainless 3/16 lines from the p-valve...

    Shift Linkage for a Ford NP205 in a GMT400

    So I’ve got a 6BT/NV4500/Ford NP205 swapped into my GMT400 truck. I’m trying to figure out the best way to connect my factory floor shifter to the NP205 and figured I’d ask around to see if anyone had done this before or had an example to share.

    Power Steering Overflows Only When Turning Right

    I’ve confirmed the lines are hooked up correctly. I’m guessing there’s air trapped somewhere and the pump needs to spin to free it up. This is for a Cummins and the pump is driven off the cam so I’ll have to wait till the cooling system is plumbed to run it and sort this out further. Thanks for...

    Power Steering Overflows Only When Turning Right

    While blocked passages from using the wrong fluid could be a concern down the road, the steering box, lines, and pump in question have zero miles on them. If any passages are blocked right now it would be considered a manufacturing defect.

    Power Steering Overflows Only When Turning Right

    I’ve always used regular power steering fluid but the steering box I got from Redhead was definitely filled with some kind of red fluid because now all the fluid in my pump reservoir is pinkish. Though none of this has anything to do with the original question...
