Straight Axle Swapped OBS Chevy UPDATE AND FAQ

[@SDRacing88]

Absolutely love the truck. From the lift, extended cab, big block, camper, this is the shizniz!!

[@Calikov762]

Thanks!

[@thrillbillyjp1]

My finding over this issue is two things - 1 frame movement/ flexing , 2 change alignment of pitman arm and if u can get high pinions for tops of hub/spindle .. if u have e let's say 2" lift run u a 4" pitman it will have much better steering response. And also make sure the track bar matches the design of pitchman steering shafts

[@scubasteve7946]

Beautiful workmanship. It looks like you really chased down a lot of the details that often get left undone by lesser mechanics. 👌 It's a shame these platforms are so difficult to SAS IMHO but then again, GM didn't design them to be a straight axle vehicle 😁

Damn good fab work performed🔧🔧🔧 One of awesome yrs for Chevy/GMC trucks. Thought about going this route on my 1stgen 02 tundra. But decided to just rebuild old system instead due to time.

[@holdenc3082]

Really nice truck. I’m thinking about doing this with my 98 Tahoe.

[@thrillbillyjp1]

Hahhhh some of us have snapped that damn fitting off the back engine. This is a sweet build man mucho props to you friend.

[@adrianlaverick8040]

With manual locking hubs you don't need to drive forward and backward to make sure. That's for auto locking stuff

[@jjscustomfabrications8234]

Nice build. Looks good.

[@caseydrahota4871]

Great info! Thanks for sharing. Truck looks awesome!

[@thrillbillyjp1]

Pinion angle is a bit to much and need another inch of drive line I reckon. But awesome build man

[@joaquin923100]

been having this truck for like 3 years each time it breaks down i think its a total loss and ends up being something simple or easy fixes, spark wires or fuses

[@joellarsen8956]

On off-road designs website, what Lift did you choose when selecting their springs

[@Calikov762]

They are Alcan 47inch long 2inch lift springs. I talked to the owner of ORD on the phone before ordering and that’s what he recommended. He said that is the same spring pack they have on their OBS ultimate adventure truck, that also has a 454.

[@Robsksas]

I zip tied my actuator to the frame and it fell off. the transfer case still shifts the only difference the light on the button flashes. it works just fine, HOWEVER...I have a manual transmission that was swapped in, not sure if that makes a difference.

[@dennissmith2560]

Very nice SAS - thanks for sharing! I just finished the same ORD setup on my 1994 2 door Yukon. I used the ORD spring brackets, front and rear, on a Ford Dana 60 Kingpin and 14 bolt, respectively. I used the Yukon OEM springs on the rear and standard Chevy 3 leaf front springs (0” lift). Question, which front ORD 10 leaf lift springs did you use? My front springs are stiff with very little flex - but I used them for the 0” lift. I’m considering the ORD 10 leaf springs in the future.

[@Calikov762]

The front springs are the 47 inch “2 inch lift” ORD springs by Alcan Spring. They ride very nice and flex well! Worth the money

[@bertollie6840]

What spring hanger kit are you using

[@alb2571]

So, what would you say it's the best pick of transfer case and differential to do this if you were to do it manual 4x4?

[@Calikov762]

“Best” haha well everyone had a different opinion. I like doing the least work possible that’s also the most reliable. Keep it simple. Stock 241 transfer case with the floor shift is plenty fine and a driver side high-pinion front axle. I have a 243 which is the electric shift version that came in the truck. I don’t feel the need to replace it because it works just fine. If you want to make things harder for yourself you can get a passenger side drop low pinion axle then you have to get a passenger side drop 241 or a 205 and pay more money for an adapter to clock it so you don’t bind your front driveline up.

[@Calikov762]

If money wasn’t an object I’d buy a driver drop NP205 and a Off-road Designs Magnum reduction box… with the adapter plates… that would be sweet with a NV4500 in front.
