Confusion is abound here... I keep seeing people differ over whether the 9.8125 (2 3/8") or 9.8117 (2 5/8") sway bar end link should be used for the rear. I have the 9.8125 in my hand as we speak. Should I return it and get the 9.8117? What REALLY makes me mad is that every catalog seemingly ignores the fact that the F-body (and I'm sure many other cars) has both front AND rear sway bar end links. ARG!

 

I used the GM 1LE poly end links for my 85 IROC; however, in advance of that purchase, I did look into Energy Suspension. My notes tell me that I was interested in Summit part number ENS-9-8117R (Red), sleeve length 2 5/8.

Can anybody tell me why I've found mentions of 9.8125?

That link is wonderful and all, but I've looked at that and the actual paper catalog. No listing for a rear sway bar end link.

 

Front and rear are the same. The 1LE poly end links that I'm using, for example, front or rear, are listed as GM 10221779. By the way, I much prefer the fashion in which the latter fit in the sway bars and a-arms. You may find that the orginal end links have ovaled the hole the in a-arm. I did a weld and grind before replacing, then after, perhaps fifty miles, I retorqued.

I also used the 2 5/8" sleeve length end links, front and rear. You can always file the sleeve down if you want to tune the sway bars further.

And as James mentioned, when I rebuilt my suspension, I found out that the holes in the lower control arm had indeed "ovalled" out. I was just too fed up/dirty/greasy/tired to weld 'em up at the time.
