Lift,slip-yoke driveshaft length : suburban

[G-Force8]

So I've seen Blazers with off-the-shelf 6" lifts that didn't need any driveshaft mods

Trying to get all my ducks in a row before I shoot

I'm planning on installing 4"TCI ez-ride springs with ORD zero-rates up front and a combination of a 4"shackle flip,ORD 6.0"rear SuperShackles and an ORD zero-rate out back with the stock 56" springs.......on my '91 'Burb

I don't want (can't afford) driveshaft work, as I'm building this truck in phases and I'll be rebuilding the NP241 later on with an SYE,bigger chain/planetary and custom built shafts

Has anyone with about 5" of lift up front and about 6" of lift out back encountered any driveshaft binding/fitment issues on a Suburban with the slip-yoke style NP208 or NP241 transfer case?

Really need the stock shafts to work for now

*also*

I will be swapping a 14BFF under the rear in place of the 10-bolt at the same time using a conversion u-joint

I have a 6 inch lift on my 85 suburban with slip yoke 208. Previous owner had dropped the crossmember with spacers about 1 inch I guess to fix a driveline angle problem that didnt exist. Almost had the motor touching the firewall. The slip yoke was almost bottomed out in the 208. I took the spacers out and placed the tranny and transfer case in the stock position and havent had a problem yet. No binding of the slip yoke under articulation and no wierd driveline vibes. The slip yoke appears to be only slighty further out than a stock position in relation to the wear marks on the slip yoke. The longer the wheel base the less pronounced driveline problems associated with lifts become.

Just saw you were going with a shackle flip, Per ORD's website they state on the longer wheel base trucks that you might have to shim the pinion down a few degrees to prevent any issues.

My buddy runs a 'burb with 4" flip and 3" block in the rear (tapered block installed backwards to lower the pinion) and 6" front springs. He didn't have to do any d-shaft work until the rear shaft got smashed on a rock.

sounds promising

I'll be driving an hour out of town to install all the lift at a buddy's shop,so, finding out the driveshaft is too short when its time to drive home would suck

I put a shackle flip on the rear of my Burb with 2" 2wd loweing shackles(~5-6 lift rear). Stock drive shaft length. No problemos.

Burbs are a tad longer than k5's. a little more leeway with the shafts when playin with lift
