This question comes up at least twice a week I think. Searching will give you plenty of information. The short answer is: not worth the effort.Howdy All,
I need to replace the springs on my 2006 TJ and rear shocks. I found a seller that has just pulled his factory suspension from a 2012 Jeep Wrangler unlimited Rubicon.
Does anyone know if these would fit on my TJ?
ha! I wish. I just think if you need a spacer to gain a lift with your lift springs, you're doing something wrong. I'm on a budget just like everyone else, thats why I do a lot of research before spending my money, I want to make damn sure I spend it well.The people who say "not worth it" probably have $1000 bills flying out of their exhaust hole.
this statement is confusing, and not helpful to anyone trying to understand the dynamics at play here.I had to buy all new bumpstops anyway, the old ones were rotten.
I got a ruler and measured the difference.this statement is confusing, and not helpful to anyone trying to understand the dynamics at play here.
bumpstops consist of 4 main parts -
1. bumpstop tower (part of the frame)
2. bumpstop pad (part of the axle)
3. bumpstop cup (bolted to tower)
4. jounce bumper (pressed into cup)
If you install a lift, you will very likely need bumpstop extensions as well. This decreases the distance between the cup and the pad to prevent damage to parts.
The jounce bumper will completely compress into the cup when driving the vehicle, and it's designed to do that. If you're replacing the jounce bumper you want to use OEM replacement stuff - it's a specifically designed microcellular polyurethane. You do NOT want to replace this with a hard polyurethane jounce or longer jounce that is often sold in the aftermarket.
Now, you said you had to buy new bumpstops. What EXACTLY does that mean? How did you know what to buy? How did you determine how much bumpstop extension was required to prevent part damage?
