The olympic carrier is a one piece 2.5" round tube so basically it isnt a bunch of mitre cuts welded together. for a complete bumper and tire swing set up you would need the following 550-15X rock rear bumper, 700-15X tire swing, and a 707-12X HD tire carrier. You do not have to get the 707 if you would perfer to get the stock tire carrier of a TJ wrangler. The 707-tire carrier is a one piece 1/4" thick steel plus it will work for a 5 on 4.5" and 5 on 5.5" bolt patterns. The rear bumper mounts are all 1/4" thick steel. The actual tire swing is secured with a steel pull pin and not some flimsy latch. Ive built my own carrier with one of the lock latches but they always seem to break, the pin is 1/2" diameter.
