Hydraulic Bump Stops

[JMP]

I ran the Fox Bumps on my JK and now my 4xe. I am paired with Accutune Fox 2.5 Performance Elite Series with the Duel Sport Tune. Excellent performance.

What pressure are you running in those Fox bumps?

I say build for more uptravel 1st. If you have room on the shock shafts to reduce the bump stop I'd start there. In my opinion bumpstops are there to keep the tires from contacting the body and to keep your shocks from bottoming out. You shouldn't be in to them under moderate wheeling. You typically aren't fully flexing out the suspension unless you are running at high speeds or hitting really technical sections of trail. At high speed the hydraulic bumpstops are the best option. For technical crawling there's no need as that type of wheeling is low speed and shouldn't be so jarring. If you're into them over moderate terrain at moderate speeds you either need to remove some bump stop spacer, increase lift height/ spring rate, or increase shock dampening (or some combination of all 3).

I added the Fox bumps and it makes a big difference in some terrain - large whoops or sudden washouts typical of the desert. You can hear when bump hits the pad but there never is a jarring bottom out.

Bump stop starts to make contact at 4.7" travel and total bump travel is 6.2". Much better than the 2.8" the factory gave me.

I have Kings and it's a love hate relationship. A factor some people don't take into consideration is vehicle weight. My Jeep runs on the heavy side so even speed bumps can cause my bump stops to engage. The hate part is, if you hear squeaking, it's very likely the collars are spinning loose despite everything having been tightened down. Keep a spanner wrench handy.
