I have an 86 IFS 4x4 pickup Ive been working on.

It has a 2" body lift.

Ive raised the gas tank, and Im in the process of doing a 2" drivetrain lift.

I am considering adding BJ Spacers and possibly a diff drop for the time being until I can SAS.

before I do I figured id ask here and see if anyone is running BJ Spacers with a drivetrain lift, and see if there are any areas of concern. Any problems with the driveshaft?
Is it possible to still do diff drop?

Please advise

 

I was running ball joint spacers with cranked torsion bars before my sas. I did not drop the diff, but the only issue I had was a couple torn boots after several hard rides

 

Did you also have a drivetrain lift?

Im mostly concerned about the length, and angles of the front driveshaft.

 

no drivetrain lift, but your front driveshaft I would think will work fine, it should be long and have enough flex for the 2" lift, I'd just make sure the pinion angle is correct,
the rear driveshaft could be an issue being too short when you start adding suspension lift though

 

length will not be the issue, iirc factory solid axle and ifs front shafts are the same lengths, the big difference is the angles of the u-joints

factory ifs shaft is limited to 25 degrees, you can clearance the cv joint to around 34 degrees

Thanks a lot, that certainly helps.

 

what is a drivetrain lift? ive heard of raising the case for more clearance is this the same idea?

 

drivetrain lift is using spacers to vertically raise the motor/trans/tcase

raising just the t-case is usually done by clocking

 

I was planning on using this same set up with my truck. Have you finished this? How did it work?

 

We have had a wicked winter this year here in PA, so unfortunately the Yota has been on hold. It is finally starting to warm up so progress should resume pretty soon. I will update this thread when I have something to report.

Additionally if you make any progress with your project please let me know how it goes.
