Some 5.13's????

6.slow · November 7, 2006

Yeah, I got rid of my 03 so's i could get a 78! Here's my dilemna... 1978 k20 with a tired 350, SM465, NP205, Dana 44 and 10.5" 14 bolt in rear... Came with 3.73's and 245's , running some 285's for now, but planning on some 38's. Looking to see if anyone around here has ever had any negative effects to running some 5.13's. 4.56 and 4.88's seem too mild... Play truck, not a highway/freeway ride. I know the rpm's will be up there, and dsthe speedo won't be right, but how much gear is too much? Anyone care to lend some advice, suggestions....? Again, this is only my play truck so street manners are of almost no concern... Please help.

What size tires do you plan on running? Are you going to lift the truck? What type of terrain do you plan on wheeling in? It's pretty tough to answer your question without filling in the blanks. It's not as simple as saying "it's your play truck and I want to know what you think about using 5.13's". There are advantages and disadvantages to using lower gears in your truck but before you decide on your gears you might want to let us know what else you plan on doing or you may end up spending a lot of money for nothing and then kick yourself for doing it.

Go with the 5.13s, if you're upgrading to 38s now, sometime in the future you will get the itch to up to 40s.

I plan on running some 38's and a 8" lift. All of which isn't till spring... I plan to use this truck in the mud. Trail running wouldn't be out of the question, as i'm not one to shy away form some character scratches... Paint only weighs you down anyways.. No "real" trailer hauling, and no "real" bed cargo. "Real" being anything over 500 llbs or so... Just a play truck. Just something I can take out and get my self "high" off the sweet, sweet smell of burning rubber and the sound of the big tire "whirrr" as i let the pedal fall... ( I've had enough of these new-age pickups that don't let me spin even one tire and i ain't gonna take it no more!) Just a "piss of the neighbors" truck. Don't get me wrong, I ain't one of them rich kids neither, I'm 25 and bust my balls for every little penny I come across. I got everything I got by my own doings! just my rant... sorry

If your going to go to 38's then 5.13's would be a good choice. You could also look at 4.88's as well.

What's the stock gears? What ya use it for? I'll tell you what i can, but I only used to run the 3/4 HD's for work and not really play. Didn't play much with the 1/2 ton's though. Maybe I could steer you in the right directio though....
