Saying what is "required" can be somewhat subjective. The best I can offer is a mention of why each may be needed and then you can decide what's best for your application. While the exact components vary by lift kit brand, most kits include these items. So when piecing together your own lift components, you may want to consider these items.I'm planning on doing the Rubi + Teraflex front + Daystar rear before I put 35's on. Do you really need to do the below steps? I've never read anywhere on this site that it was a requirement to do this combo for the lift (not saying it's wrong, I'd like to understand why they're needed):
$78 - rear bump stops from Mopar lift (68316588AA)
$93 - end links from Mopar lift (68306981AA and 68436812AA)
$61 - lower control arms from Mopar lift (68322798AA)
$118 - shock extensions from Rusty's offroad (Front - $59, Rear $59)
Bump stops are used to limit up travel. Some coil springs can be damaged by completely collapsing the spring, and it helps keep larger tires from hitting the fenders. If you never go off-road and fully flex the suspension, then you could probably get away with not using them.
To keep the proper angle between the sway bar and the end links, the end links need to be extended when the suspension height is changed. If the end links are too short, the sway bar ends are pulled downward at ride height. If they are too short it can also limit down travel in the suspension droop. If the end links are the limiting factor in droop, the weight of the axle is hanging by the end link, and could damage the sway bar mounting points.
As you lift the Jeep, you lose steering caster. One way to get the caster back into spec is by using longer lower control arms. The Mopar kit uses fixed length control arms when can be had very inexpensively. Or you can use adjustable LCA's, which are more expensive but are typically strong and adjustable.
If you install a lift but use the stock length shocks, you are limiting your suspension droop. You can either install new longer shocks (such as the Fox 2.0 shocks that come in Mopar kit) or you can use shock extensions with the stock shocks.
So in many ways what is "required" depends on how you use your Jeep and what you're willing to tolerate in terms of handling changes.
