    Tallest transmission tunnel?

    I had a shop install my magnum doubler in my '77 K20 probably 2 years ago... should have done it myself. They used 2" square stock to drop the transfer case/doubler down from the frame. I don't like this. I have a rear driveline vibration now. Have to tilt the rear axle pinion down or raise the...

    Pro Flo 4- hate to try again after Edelbrock E-Street EFI

    So I spent $2,489 back in September 2015 on Edelbrock's "New" E-street TBI fuel injection. Better than a carb, but has issues. It was the 1st generation. Had issues. They came out with a second generation. Had issues. Then the discontinued it. Problems: Cannot set the idle RPM to 650. My HT383...

    Be safe when trying to pull out a stuck vehicle-

    My local off road club had a link to this article. I'm not a facebook person but can still access and read it: hitch breaks off and kills stuck driver <-- link Mistakes were made and someone was sadly killed for it. It's easy to say after the fact to "always have the proper equipment" but...

    Tilden Motorsports LS used engines

    So my father in law offered me his old GMC K15.(1984?) It has been sitting in a field since probably 2003? If I remember right it has the 305, and he said it ran horrible when parked. I'm sure it hasn't gotten any better. I started thinking about just putting a "generic" GM crate engine into...

    NP203... no 4 wheel drive

    So a few weeks ago I was testing my new tires. Drove up and over a pass. 4wd worked fine. Put it in 2wd and drove down the 10 mile dirt road and then got on the highway. Probably 10 miles down the highway while cruising at 60 mph there was a sudden bang/clunk noise and I saw my transfer case...

    Ultimate Adventure 2020

    Not sure how many of you have ever followed this- it is what Four Wheeler has done every year for the last 20 years. About half the group is the editors, or Steven Watson from ORD. The rest are reader voted rigs. I think last year they were in Alaska. So check my email and it says UA2020 has...

    Crossover steering clearance issue

    So I thought I was going to be done today on this- but just realized I'm in trouble. I have offroad design's front custom leaf springs. They have about 5.5" of upward travel. The "ball joint" hangs down from the pitman arm so far that I only have around 3" of clearance between it and the top of...

    Warn hydraulic winch?

    First of all- I gotta say I've never owned a winch of any kind. However in the off road club the other members almost all have winches. But all are the electric kind. And I've seen a lot of problems with them. Overheating, melting, whatnot. I am thinking about buying ORDs front bumper. It has...

    Dana 44 fill capacity- is there ever "too much"?

    I bought a Riddler protective differential cover for my front axle to match my rear axle. I saw on the packaging as a benefit it said "additional fluid capacity". The cover itself is physically about the same size as the stock one. Before I replaced it I measured from the fill port on the stock...

    Transmission cooler mounting

    I'm finally getting around to installing a transmission cooler on my truck. It bothers me it comes with some little rubber spacers and some zip ties. Really? Is this an acceptable way to mount one? In one way I can see that it would probably get more airflow thru it vs trying to make some...

    Beadlocks

    Anyone here run any? I aired down to 5 psi with my standard steel wheels last weekend which was a new low. In the past I try to stay at 7-10 psi. So far I haven't lost a bead but if I did, I'd have a hard time fixing it in 3+ feet of snow. I have seen a few manufacturers say there is a limit...

    destroyed hub- bought new "locking" spindle nuts

    Never heard this was possible on the highway. While I was out of state there were some bad rain storms with wind. The wife was driving my truck, she got home and said the whole wheel was smoking. Pretty much everything that used to be my Yukon locking hub is now a pile of shavings. !/2 the...

    @#!$%$& Seized brake calipers

    My state here LOVES to slather on de-icer onto all the roads. Often I see those bastards out at 5 am dumping it onto dry pavement. Forecast for the day? 10% chance of light snow... I've had 2 seize up this year so far. One rear one (yes, disc brake conversion) and now a front one. I lose...

    Transmission cooler for off road/crawling questions

    Yesterday I spent all day with the off road club heading up to different old fire lookout sites. Of course these are up on top of mountains and the trails we took often went straight up the side of the mountain. Outside temp was around 79 degrees. I spent pretty much the whole day in 2 low or 4...

    Dirt every day- stock K20 on the Rubicon

    https://www.motortrendondemand.com/detail/stock-trucks-vs-the-rubicon-trail/0_z71jxi5m/ This will only be free for a little while- then will be locked until probably next year. I thought this was pretty cool- until the tree scene... I'd love to take my truck thru there someday.

    Found some on sale. These will be required when I go to crossover steering. Never replaced knuckles before- and at the same time I will be replacing the axle shafts. What should I replace while I'm in the area? -axle seals? (timken?) -bearings? (timken?) -??? -the upper/lower ball joints will...

    D44 aftermarket axle shaft companies

    Any of them better than others? Any to stay away from? So far have looked at Yukon, Revolution, Ten Factory. Looking for a stronger chromoly replacement vs the 40 year old OEM axle shafts. Running 315s (35") tires and primary purpose is off road. Getting a D60 isn't an option unless you have...

    Volt gauge

    My dad and I did a 6 hour road trip in his 1979 GMC K15 yesterday and I got to drive his truck. I had only made it about 50 yards from his house and was checking out his gauges and saw the volt gauge was only reading about 12 volts. Stopped and turned around and went back to the house. Had him...

    Testing day at ORV park

    With the new tires and new suspension work I went to the local ORV park to check for tire clearance, brake line lengths, just a general shakedown. Since I work weekends I was out by myself which isn't a good idea, so I just did some mild trails. Not good at video- maybe this will work. With no...

    Aftermarket tach, MSD ignition box

    I'm in the process of wiring up a MSD ignition box and they say the tach cannot be hooked up to the negative side of the coil. (not sure why, does anyone know why?). Instead they say hook it up to the grey tach output wire. I have issues with this. The grey wire needs to go to my Edelbrock...

    Need a new ignition module

    I have went thru 2 of these in the last 2-3 years: It is a MSD ignition module that fits inside the distributor. This was the "cheap easy route" for me to go as my fuel injection unit needs a digital square wave for the tach output. They are "only $115" or so... Simply grabbing the tach...
