Re: Finally starting my Longhorn 4x4 conversion
Today the correct DIY4X rear shackle brackets arrived. Too bad there are no shackle bars.

Re: Finally starting my Longhorn 4x4 conversion
Dieselwrencher, I am loving your build and plan to do the same thing to my 71 C20. My question to you is did your truck have factory rear coils, and if so, could you provide more info on that conversion? I apprciate all the pics and info you posted on the front end. It made a big difference in the confidence I had in myself to do the swap to the 2wd frame. Thanks!

Ok, thanks for the info. I'll check out the link Tim provided and take some more measurements.

they do look beefy for sure though. also i might recommend that you tie the two side plates of the shackle together somehow. since i doubt you are building a rock crawling/tow machine the added stability will be a benefit to you. looking forward to some pics with them installed. Ryan |

Re: Finally starting my Longhorn 4x4 conversion
The Diy4x is plenty beef. I run it on my 77 K10 and wheel it all the time and tow .. with it. The brackets are way beefier then the stock stuff. It does stink you have to buy the shackels seperate or build your own. The Diy shackles are stout too. I run there cross tied ones.
BTW this is a impressive build. Nice to see someone stick with a project .

Re: Finally starting my Longhorn 4x4 conversion
Seeing how now I will be building shackle bars, I will tie them together. It's weird they didn't send any at all. You guys have a great Sunday!

Re: Finally starting my Longhorn 4x4 conversion
As far as I know 89-02 will work. When you get to that point, let me know.

This depends on the transmission you go with. Getrag G360 takes the 89-93 12 1/4" flywheel. NV4500 will accept a 94-03 12 1/4" flywheel or with a starter spacer a NV5600 99-05 13" flywheel. I would recommend sticking with a 12 1/4" clutch as they have 22% more friction material than a 13" clutch.

My dad is is swapping out the getrag and transfer case for a 2wd nv 4500 for his peterbilt pickup. So it looks like he will need to swap flywheels. and I can use his old one for the getrag? my dad is trading me the parts he isnt going to use. Dana 60/70 np getrag/np 205} All L have to do ![]() i am confused about how the 12.25clutch has more friction materal.And what are the diffrences in the two 12.25 flywheels? I am not douting what you say but trying to learn more about these great little engines. Thanks to both you and Ryan for the info Mark Last edited by mknittle; 06-04-2012 at 08:26 PM. |

i 'think' that i also used ORD cross tied shackles with those DIY hangars and everything fit like a glove. i'm in the process of prepping the drive train now (427 truck motor, 465, 205) you can also D&T the tube of the DIY hanger in the middle for a grease zerk instead of using drilled bolts, should you want greasable stuff... |

Re: Finally starting my Longhorn 4x4 conversion
12 1/4 clutch disc setup
http://valairinc.com/performance/images/nmu70119-04.jpg 13 clutch disc setup http://valairinc.com/performance/images/nmu70279-04.jpg The physical size of the button/clutch material is where the difference is found. The 12 1/4 is physically larger. And I'm wrong the getrag will swap with the NV4500 according to ValAir: "We no longer offer replacement Getrag clutches. The 12 1/4" NV4500 clutch will fit your stock Getrag flywheel or you can upgrade to the 13" conversion kit found here. 5 speed 13" upgrade." Nick

Re: Finally starting my Longhorn 4x4 conversion
i am thinking a little here again (always sketchy business... me thinking) but if the apply pressure from the pressure plate is the same, the lesser friction material may have a better chance at holding torque while also causing more chatter. the idea is that less area with equal force would end up being a higher apply pressure. then of course the friction material and surface condition of the metal surfaces would play into the equation as well. and also the increased leverage that the bigger diameter clutch plate has on the input shaft would also increase its effectiveness as it would have more mechanical advantage on the shaft. that would probably only help in the engagement not necessarily the maximum torque holding capacity once engaged.
is there a notable performance issue with the 13" vs the 12.25"? ryan |

Re: Finally starting my Longhorn 4x4 conversion
My shackle bars arrived from DIY4X. No other real progress on this except trying to find where I hid parts for it.
