rough country long arm

So my buddy finally got around to getting his front drive shaft... getting ready to install it but the pinion angle is just about pointing at the bottom of the rear diff... all the arms are adjusted to RC specs.

Anyone have measurement s that work well for them on a 4 inch RC long arm for the front?

Upper and lower.

All the threads I find are on short arms

Maybe this chart will help you to at least identify the length needed.

Don't worry about lengths. Center the wheel in the well, take one side off, adjust the other to get the pinion angle you want, then match the two sides.

Thanks, that's what I ended up doing... its great now.. lower long arms are at what the instructions said. And uppers are at 15 5/8 no drive shaft vibes and drives perfect... the 265/75 16 do rub the front number under full flex but not bad
