YJ4LIFE 02-28-2002, 01:36 PM I always wondered how important the shackle angle was. thanks. HighHooder 02-28-2002, 02:04 PM how about.... VERY!!!! if your shackles are straight up and down you won't get much deflection out of them, making your ride very stiff. If they angle towards the spring you get good articulation, if they angle away from the spring you don't... did I miss anything??? YJ4LIFE 02-28-2002, 02:10 PM ok, because I'm looking at waggy springs (4" SUA BDS front springs or stock waggy fronts SOA) which will give more angle. 2 of my friends have procomp 4" springs on their YJ and shackles end up verticle. TRD 02-28-2002, 02:37 PM you want a 45 degree angle for wheeling (a little soft for a dd though). chadl 02-28-2002, 02:48 PM Here's one of many posts I found searching on this subject http://www.pirate4x4.com/forum/showthread.php?s=&threadid=24832&highlight=shackle+angle but to sum it up, if you are using flat springs, any movement (up or down) is going to decrease the distance between the spring eye's (arching), therefore you want to make sure you shackle can accomodate this. if it's angled back toward the spring, I don't see how it would (at least not very well) I think verticle, or slightly angled forward is what you want, however, if your spring is arched, for it to flatten out (wheel go up) the spring eye's have to be able to move apart so you need your shackle to accomdate that. Just take a look at your springs, measure the length (arched or flat) along the arch (not directly eye to eye) and then measure from your solid mount straight out to your shackle where ever that distance ends, is where your spring will max out (length wise) make sure your shackle can accomodate that. There maybe other factors (espcially for on-road use) that come into play, but the above should ensure that your shackle isnn't limiting travel... chad Brandon 02-28-2002, 03:37 PM more angle more drop, I got a good 45 degrees on my jeep with flat springs http://www.rivercityrockcrawlers.com/temp/P2232021/P2232021.JPG HighHooder 02-28-2002, 03:48 PM you gotta love a Jeep that came stock with trailing shackles:cool2: Brandon 02-28-2002, 03:52 PM yea, bummer having to put new mounts on it - went to wider wranger springs but you can still see the stock hole in the frame :)
