    Wire coming out of rear shocks

    I don't think air shocks were ever stock. I had a '78 K15 that had air shocks when I bought it from the previous owner. The airlines went back to the rear bumper where they drilled in a schrader valve. If yours is going up to the cab some shock companies made an in cab controller to change the...

    Wire coming out of rear shocks

    A picture might help. You sure it is a wire and not an air line?

    Snow wheeling. Now I want to re-configure...

    Can't find or buy a new chain for a NP203. They seem to be backordered months and then want several hundred for a new chain. So gave up on that. Found a full time NP203 in a junk yard and had the shop put that in. Twin stick is kinda nice- easy to shift. But the right shifter linkage (I'm...

    Warn hydraulic winch?

    I'm probably a year out from buying a winch. Need a winch bumper first- but good to hear different input from people. :waytogo:

    Driveline Opinions

    With the full time 203 you won't get stuck then have to climb out in the snow/muck to lock in the hubs (hey- it happens). And since the truck is full time 4 you won't have any issues of the rear end suddenly trying to slide out on you in 2 wheel drive. A limited slip can cause you to lose side...

    87 2500 4x4 truck build

    You have a good rear end ratio for pulling. Depends on the weight of the 5th wheel. Not advisable towing at 70 mph. Better to slow down as trailer tires usually aren't happy at speed (speed equals heat, then blowout). It *could* probably tow at 70 mph but then your fuel economy will greatly...

    Warn hydraulic winch?

    I have done some more reading about hydraulic winches- it is hard to find a PTO hydraulic pump. Some of the pumps work only one way (they are not reversible). This is important as when you would go to use it you put the transfer case in neutral and then you put the transmission in gear (reverse...

    lift advice 4" (1 Ton)

    Shackle flip provides lift, better ride, and still retains the stock spring load capability. https://www.offroaddesign.com/ Check out their website- can learn a lot from that website. And you can call them and ask them questions- even if you aren't buying at that right second. I called last...

    Cooper Discoverer MTP

    i didn’t sipe these- I did to some mud terrains probably 25 years ago and it was great for winter but with all the summer driving on dirt and gravel they chunked up badly. the rubber compound is different now- but haven’t tried it.

    Cooper Discoverer MTP

    It is funny how many opinions there are of tires. That being said there are a lot of different conditions out there and some tires at that particular day, time, and temperature will just work better... I was almost all set to buy the Cooper STT Pros, but then found a rebate or sale on my BFG...

    Lift Blocks

    With something like a 2" block your brake lines should be fine. Just get new U bolts and add the blocks.

    Looking into a new compact car.

    The ALH TDI was the best one by far. I had a 2000 Golf with the manual trans (automatic had problems and sucked down power and fuel efficiency). Previous owner kept a fuel log of every fillup. He encouraged me to do the same and I did. At 140,000 miles or so the fuel mileage dropped down to...

    Dream truck, shes a wheeler

    Do you have any pictures of your doubler transfer case setup? I'm looking into the Magnum/205 option which should look very similar to the 203/205 doubler. Did you install it yourself? If so what transfer case did you have previously? What did you do with the crossmembers? Move one and added a...

    72-older SBC ram horn manifolds on a 73-up?

    They were the larger 2.5" ramhorns. They were tested on a chevy small block, wasn't stock but had a mild build to it. Not sure what the displacement was.

    72-older SBC ram horn manifolds on a 73-up?

    When I was doing research on mine I had found some actual dyno runs between full length headers and the ramhorns. They were very very similar in power until the upper RPMs (5,000 RPM+) Then full headers are better. I can no longer find that page. But with my 400 and now my 383 there is no "high...

    NP203... no 4 wheel drive

    The junk yard did have a NP205 there- but they want $300 for it and it has the wrong input splines as it was for a manual trans. They said the transfer case needs to be rebuilt also as when you spin it by hand it isn't smooth. A new input shaft is $150 plus shipping. I did find another 205 that...

    NP203... no 4 wheel drive

    Another small sad update. Shop said it would cost around $900 to rebuild my existing transfer case- and will probably take a month or two. Parts are hard to come by/backordered. So I did stupid option #2- I bought a used full time case at a junkyard today ($225). They do offer a 30 day...

    72-older SBC ram horn manifolds on a 73-up?

    I bought some 2.5" center dump manifolds 8 years ago for my 400. The exhaust shop said there was a slight clearance issue on the driver side with the manifold and the clamshell. They cut out part of the clamshell and welded on it underneath to strengthen it back up. The 400 was then replaced...

    Does this look correct to everyone??

    You have an awesome clean platform going there and I think you will be very happy with their stuff. The ride quality on it will be great. Do you have a build thread going for it?

    Does this look correct to everyone??

    If you get the "short" shackles they would provide 0.25" of lift. If you get the long shackle then it would lift by 1.25" And if you are going to put in an order I'd go ahead and get those axle relocation plates. They are pretty cheap. And moving the rear axle back a bit will help with your...

    Does this look correct to everyone??

    Since I'm using stock 56" springs ORD told me that my shackle angle will be a bit farther back as the flat spring pack can't get much longer. But with the shackle leaning back then it allows a lot more droop when needed. And these greasable bushings make sure that spring movement is unhindered.
