Jeff, something's wrong. The springs are 8" long but at Summit all their 8" long are 3.5" OD and I measured 3.25" OD. As for the ID I measured 2.33-2.4" but at Summit they have 2.25" and 2.625". Maybe they are 2.25" but I'm still 0.25 off on the OD, maybe it's not that much?


At the back they are Koni's 275lbs.
