Couldn't be happier with the Crow Enterprizes harnesses in my Jeep. Called them up and they added length to fit the stock seat mount locations and my larger frame better. Also had them built and to me in less than a week so I could get them before heading to Moab. Running 3" 5point with their pro kamlock, pads, sternum velcro. I am using the Synergy B Harness pillar bar (similiar location to the RockHard bar) and the Synergy mounts for the lap bolts as well as the sub bolt.
Took a minute to figure out how to get the kamlock hooked in quickly but after a week in Moab I really really like it. Did very well. And I can still run the normal seatbelts on the road.
I would absolutely recommend the adjustable sub belt. On mine it keeps the harness down at the right height so it doesn't ride up. Not uncomfortable at all.
