1989 CK-style Crew-Cab GM conversion Complete

[RyanB]

Hey all. Its been quite a while since I posted some pics and now finally my conversion is complete...well 95% anyway...I still have some bugs to work out and a bunch of saftey stuff to do yet for pulling (loops, air shut off and stuff like that)and also put my twins on.

Anyway, here is the list of mods that were done!


The truck was originaly as follows-

1989 CK-style Reg-Cab, 2 wheel drive Dually
350 gasser
Turbo400 Tranny
Dana70 Rear
Power Nothing
Needed TONS of body work


Here is the list of mods just off the top of my head!

Crew-Cab (stretched frame, bought a wrecked cab, spliced my firewall to it (wrecked cab had fire wall pushed in to far) Cab was a 1999 and had new interior and leather seats...power everything and all wiring I needed)

4x4 conversion- I used my coil sprung 2wd frame. Put a Dodge D60 under it, reworked all the mounts to work with a set of 2005 Ford Trailing arms. I located a custom Panhard Bar behind the diff instead of in front because of frame clearence. I also removed alot out of the crossmember but re-enforced it with 1/4" and looks better than stock and is stronger. I also put a ARB locker in the front diff.

Transmission/T-case - I used a 2003 Dodge 6-speed and a 1998 Dodge NP241 HD. The clutch is a Haisley Machine Dual Disk Competition Puller!!! The rear drive shaft is now a single shaft (84" long!!!) 4" heavy wall tubing.

The rear axle is GMC 11.5" AAM dually axle with a few goodies!

The engine is of course a 5.9 Cummins. Custom built by Haisley Machine in Indiana. It is 14mm studded (stock is 12mm), Dual fire-ringed! Custom ground cam shaft, Custom flycut low comp pistons, Ballanced and blueprinted, Fluidampr, Studded bottom end and girdled! and a whole bunch more. The P7100 pump has a custom cam, Plungers and Barrels bored to 13MM from 12mm. A 5000rpm gov kit,Haisley 5x18's injectors!!!! Custom stainless lines and a hole bunch more! I also have Twins for the truck (not setup yet) They are a HTT Sled-Puller 66 with a custom wastegate and the large turbo is custom by HTT also. I had a HT3B/26 but they put some #'s together for me after my pump was built and figured it was to small. As for an idea of what the pump flows...I had them detune it to 750cc's @ 1000stroke per minute/4500rpm. I also have a Snow Preformance kit that I have yet to put on and a Haisley AUX fuel kit for my fuel needs.


I also used a 6.5L rad for the conversion and a 2004 Duramax Intercooler. The rad fits amazingly into the D-Max IC. Now fitting the IC to the rad support was another story but I made it work! My rad support looks just like it did stock...nice and clean looking and everything works! I don't have any pictures of it yet other than the one posted but in a few weeks when I setup my twin turbo's I have to pull the rad again so I will snap some pictures.


What else....Alcoa wheels, 3.5" Goodmark Cowl Hood

Oh...and probaby about 6000 Hours of work...felt like that anyway!!! and you have no idea how much $$$$


As far as the suspension goes. Its a Dodge 60 like stated above. I had just had to do some minor changes to the brackets to make the Ford Trailing arms work and it seems to work great! I also used the stock GM 2wd springs but had to use a set of shocks from a 1980's style ford just because they have a different mount on the bottom than the GM style did! It turned out great for using all stock pieces and its a nice clean look!



If anyone has any questions feel free to ask!!!!

Thanks...RyanB
