How much lift with Rusty's ROPXJ35-0?

My donor XJ came with new full spring packs on it. They are marked ROPXJ35-0. I'm assuming that stands for Rusty's Offroad Products 3.5" lift, but can find nothing on their website to confirm. The front springs are Rusty's 300 (3”) and the XJ was low in the front, so that makes sense. These springs have not been used, so they may settle. Heck, the bolts weren't even tightened from the install as this was an abandoned project. Anyone know for sure how much lift they are?

My XJ has a RC 3" lift with AAL. I'm thinking about leaving the RC springs up front but replacing the rear spring packs with the Rusty’s. Who's front springs are better (without starting a fight), Rusty's or RC?

Thanks,
Tom
