LS Swap Help: Drive Shaft

Basic Setup

Drive shaft angles can be a tricky subject. We don't recommend running anything more than a 15° working angle without a CV driveshaft. (Example: the drive shaft is at 20° and the engine trans angle is 5° meaning the working angle would be 15°.)

Proper Geometry for Conventional Two Joint Drive Shaft:

*Centerline of Pinion on differential & transmission are parallel

Proper Geometry for C.V. Drive Shaft:

*Centerline of Pinion on differential points at transfer case output

 

 

Anything Scout Recommendations

Below are our typical setups. All of this can change depending on your specific setup so make sure you understand the concepts and needs before choosing your layout. 

Stock Height - No changes needed. Get a new length drive shaft and hit the road!

2.5" Lift - Two joint slip drive shaft w/ slip yoke eliminator kit on NP241c.

4"+ Lift - C.V. drive shaft w/ slip yoke eliminator kit on NP241c. (This will likely require the pinion angle to be raised.)

 

How to Measure Your Drive Shaft:

Standard Applications:
NOTE: Measure with weight on the suspension.

Reverse Shackle, Revolver Shackle, and Buggy Spring Applications: 
NOTE: Measure fully compressed and fully extended.
