Core's Tier 1 control arms with bushings in both ends make them a terrible design. Really. Bushings don't flex as well as flex joints do. That can be a serious enough problem that they can place enough stress on the control arm mounts to physically rip them away from the frame or axle where they are welded in place.I was interested in the Core controll arms, they look to be the best bang for the buck.
Tier 2 should be fine for the uses you described.I was thinking the tier 2 would be ok for me.

Jerry FYI, I just went to Core 4x4 today to inquire about making me some custom arms. Spence, the owner gave me a 30 second tour and showed me their shop as we went to take some measurements. Their bushings are not a solid bushing and are similar to a DDB or the metal cloak, which suprised me but they are NOT a DDB, Metalcloak, or Girro joint. They are some type of poly that will rotate and flex within the joint about 15 degrees side to side. Also, their higher end arms use real JJ from what I could see. I could not build a set of custom arms for what they are willing to charge me and they have a real nice pair of CNC lathe setups. I will try to get a few pics when I go back in a week or so. Their prices were not too bad and just like some of the other suppliers, their stuff is MADE IN THE USA.Core's Tier 1 control arms with bushings in both ends make them a terrible design. Really.

If you buy their better arms that have Johnnie Joints they'd be ok. I'd stick strictly with their Tier 2 with a Johnny Joint on one end and rubber bushing on the other, or Tier 4 with Johnny Joints on both ends. I wouldn't want anything with polyurethane bushings like in their Tier 3 design which are prone to squeak and they don't flex as well as rubber does.
For the cost of their Tier 4 arms I'd rather run Savvy or Currie control arms that have Johnnie Joints in both ends.
Upgradeable and the fact that they have a "you break it & we'll replace it" warranty..... Seems pretty damn good to me.I was thinking the tier 2 would be ok for me.

Well? Its been about 9 months now, anything to report back?Just installed a set of Core 4x4 Tier 3 lowers. Uppers will come next month. Johnny joints at the frame and tapered flex poly at the axles (very impressed with them so far). I'm willing to be a test mule for them. I'll report back good or bad.

Well, they look and perform great. I recommend highly. I've always been the guy who is not afraid to try something new, even if I have to learn a lesson or two along the way. In this case I have only positives to report.Well? Its been about 9 months now, anything to report back?
None whatsoever. They have a grease fitting on them that actually take grease quite well. I have not had to touch them since the install.Any squeaks?
