    Found some used tires - questions

    I found a set of 4 BFG A/T 31x10.5x15's on craigslist. Pretty decent price, previous owner says they have around 5k miles (he went to a bigger tire). I asked about any previous repairs - notes that one was flat when truck was in storage and has a little sidewall cracking from that. Is that...

    wheel and tire help

    On stock suspension with no lift - 33"s will fit, that is what I have on mine. Its really tight. I have 33x9.5x15's on mine, I would much rather have 31x10.5x15's though. The 33s are just a little too big and they are so tall it gives me fits with my 700r4 and 3.42 gears.

    should i lift?

    Also - the stock 1800-1850 lb springs are 6-leaf as well. So you could have either rating. There is a 5 leaf spring, which is actually stronger - 2150 lbs - as well.

    should i lift?

    I have the 6-leaf springs on mine. I looked at the rating, it is 2200 lbs, not 2350 like I thought. There is a 7-leaf spring available in the 52" size, which is rated for 2775 lbs, I thought that was probably overkill and went with the 2200. Stock K10 springs are around 1800-1850 lbs I believe.

    should i lift?

    I bought my replacement springs from General Spring online. They are nice and well built. I think they are around half of what LMC costs. I got the HD 1/2 ton springs for mine (I think 2350 lbs over stock 1800 lbs per spring) as I use mine as a farm truck.

    should i lift?

    I dont know what these even go for used, I would probably want to know what shipping would cost first. I have the raised steering arm, the front and rear springs and the front and rear shocks. No bolts or u-bolts. My truck came with the lift newly installed, i didn't want a lift so I...

    should i lift?

    If you decide to go with a 4" lift, I have a Rough Country kit off my K10 that I would sell. Has less than 2k miles on it. I re-used the bolts to install the stock springs back in, so you would need to get your own of those.

    What have you done to your square lately??

    Its not the stick on foam, but its pretty similar. Its a stick on rubber, on the shelf right next to the foam. I almost used the stick on foam, but spent extra for the rubber. i was a little worried the foam wouldnt last and that air may blow right through it.

    What have you done to your square lately??

    I hate wind noise in the cab, so I bought some generic weatherstripping from the parts store the other day. Installed it on the door front where the door meets the cab, its like a 2nd seal. The difference is amazing, I recommend this to anyone. Much quieter now.

    TBI - Cam / Vortec Heads / Upgraded Trottle Body - Any success stories?

    Looking for a very mild cam upgrade. If that is going to push me to 300 hp, maybe I could cut out one of my items there. Although my thought is that I need them all as they will work together. Any thoughts - maybe the Ported TB is overkill?

    TBI - Cam / Vortec Heads / Upgraded Trottle Body - Any success stories?

    Hello All, For the past year I have been researching upgrades to the TBI 350 in my 87'. There seems to be a lot of roadblocks to upgrading these engines. Mostly they are due to the restrictive Throttle Body, Heads and the ECM. I am not looking for serious racing performance, I am...

    My 700r4 is dying - what are my options?

    Thanks for the information. The instructions say that they may be modifications needed for the cat. Any idea what those are? Also - what about my speedometer, will I run into any issues there? Sounds like this is the best route.

    My 700r4 is dying - what are my options?

    Would it be better (easier) to find a combo TH350 and transfer case or just get a TH350? What about speedometers and cables? What are the small things (issues) that I would run into? What I am trying to find out is - if I want to go with a TH350, what is going to be the most bolt in...

    My 700r4 is dying - what are my options?

    Eariler this week the trans in my 87' V10 starting to slip in 2nd gear rarely. I drove it tonight and its slipping in 1st, 2nd and 3rd gear if you push into the gas a little bit. If I am cruising at road speed its fine (so far). Anyways, its going to be dead sooner or later. What are...

    Tach Wiring

    Im not really looking for ideas on where to mount the tach - I plan on mounting it below the dash, under the radio. I am hoping someone can point out the places where I should be tapping into wiring. Should I pull switched power from the fusebox or somewhere else? How about the ground or...

    700R4 shifting issues

    That sounds just like my Trans in my 87' - Pretty sure mine is starting to go as I felt it slipping a little the other day. Never gets into OD unless going down a hill. I have 3.42 gears with 33" tires as well. I started just running in D instead. Hoping my Trans lasts, the TV cable...

    Tach Wiring

    Hello all, I have a Autometer Tach to install in my 87' V10. What does everyone use for power source on these? I believe i need to tap into the lights, power and ground. Is there a common spot to connect all these wires? I'd prefer something which can be reached without tearing out the dash.

    14 SF 6-lug Axle for 73-87, what is the best option

    My understanding is that the light-duty 3/4 ton K20's all got 8 bolt Semi-floating axles, not 6 bolts. Is that correct?

    14 SF 6-lug Axle for 73-87, what is the best option

    Hi All, I have been planning to swap in a semi-float 14 bolt 6-lug axle. I thought that some K20's came with this axle in 6-lug version, but it seems I was wrong. I looked at a K20 once that had 6 lug wheels which is why I thought they existed, I wonder now if it was a K10 with k20 Badges...

    Vortec Heads on TBI - need info/help

    Hello All, I have been looking for ways to get some more power out of the old TBI in my 87' Silverado with the 5.7/350. It does fine but really struggles on highways to keep moving. I have done a lot of searching and found some information on the vortec head swap, but still have...

    What have you done to your square lately??

    The door seals and window seals were pretty easy, I would say it take anywhere from 20-40 min per side on the door seals (have to remove a lot of trim and then reinstall). The window seals took around 2 hours each side, but that made a huge difference - its like a different truck now. The 2nd...

    What have you done to your square lately??

    Here is what I have done with my truck in the past few weeks: -Installed new door seals -Installed new window seals and anti-rattle seals -Did the pex trick on the stricker (this really works, I was amazed) -Installed new ball joints in the front axle, also did new u-joints and new brake...

    3/4 ton axles onto my 1/2 ton K10

    I thought about doing this as well, I think instead I am settling on finding a 9.5" 14 bolt semi floater. Its a good upgrade over the 10 bolt and I can keep my 6 lug wheels. They both would use a 10 bolt front (1/2 or 3/4) so I feel like its a good way to upgrade without having to change...

    Truck died when switching tanks

    I am interested in this as well - My truck does the same thing. When I switch from the left tank to the right tank, the truck dies instantly. The previous owner told me both worked, but the right side was dry when I got it. I put around 2-3 gallons into it but everytime I switch it tanks it...
