RC 3.25 vs 3.75 , some questions

I know this has been discussed but I've searching for days and can't find a straight answer . I have an 07 sahara unlimited.
I was looking to pull the trigger on the RC 3.25 but i read that i will need a SYE/ driveshaft which is definitely not the route i want to take $ wise ,, then again hundreds of people have 3.5 plus of suspension with no need for an SYE . I was told 4" plus then you need longer driveshafts and what not

Id rather not lift the body , but if it'll save me a grand then sure.. This is simply for road use, 35" tires and minor trails 1-2 x a month

Also do both of these kits level out the front and rear or would i need to get some front spacers

thanks in advance

JKs don't need sye but drive shaft, at 3.5-4" is when you'll want a front one at least on the unlimited. A 2.5" lift can get you to 35's without the need for drive lines. I would consider new gear ratio, though.

IMO, I would be more concerned about rear drive shaft than front. Reason, the front is a high pinion differential and can tolerate a higher lift with less offset and it only runs under load when in 4wd. The rear, esp on a two door, has a greater angular offset and would benefit from a double cardan joint DS...

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.

Right. The rear went out on my 2 door before the front. However, he is a 4 door. The rear driveshaft on the unlimited is longer so it is more forgiving at 3.25-3.5"

Personally, I'd opt for the RC 0" lift or get a 3" quality brand.
