So lets say I have a 2.5 inch lift now, and I want to go to 4 inch. Standard SYE or SS SYE?A standard SYE is good, it’s just longer, so your driveshaft is shorter. That means the driveshaft angle is steeper. If your lift is 1-3” and you’re not planning a tummy tuck, you’ll be fine with standard.
A SS SYE is good too, it’s just shorter, so your driveshaft can be longer. That means the driveshaft angle is less steep. If your lift is 4”+ and/or you are planning a tummy tuck, you’ll want a SS SYE.
