CV driveshaft and SYE - Ordering Questions

Is it possible to order the SYE and driveshaft without installing the SYE first?
How do I measure the length I need?
This is my daily driver and I do not want to take it off the road for any period of time.

Thanks

get the measuremeant of your stock shaft from the center of each u-joint and write it down. u can place your driveshaft order and they can take the number u give them and account for the stock slip yoke length and your lift height and make you a near perfect DS for your SYE project.

good luck

So, I measured and its 28 3/4" the rig has the RE6130 4.5: lift installed.

I ordered mine from tom woods drive shafts and they had me measure from the rear seal on my 242 to the center of the u-joint on the axel and they sent me a drive shafts the perfect size. They had me do this becuase I was swapping in a rear 9".
