Im hear at the Easter jeep safari and we ran golden spike which is an extremely difficult trail. Today was the first real test of the bump stops and they performed amazingly. Thisnisban extremely challenging trail that resulted in a rolled jeep and many other broken jeeps. We were in a group of 49. I tested my stops at high speeds and also slow speed down steep rocks. I never felt the front end bottom out. The stops engaged and did there job. At this time I only had the front bump stops but am not sold that I need the rear bump stops as well by king. Many others on the trail watched them work and looked at the installation and plan on getting the bump stops.
On a similar note my king adjustable shocks were amazing as well. I could go at high speeds and could control the jeep even in wash board situations. I found that the shocks also were awesome on rock crawling. Their travel was excellent which allowed me to really go down extremely steep sections of the trail. I will try to post picture when I get back.
I will be doing more testing tomorrow. Bottom line, these king hydraulic bump stops are worth purchasing, king has really made it easy to make a modification that makes a big difference.
