Does anybody have one of these shocks on hand can measure the bolt hole to bolt hole length at full extension?

According to Summit, 20.5" (13" compressed)



I'd say this is accurate cuz I compared the dimensions of the Bilstein shock that I'm running to that Belltech shock and found that they were nearly identical: 20.39" extended, 13.01" compressed.

Yeah I wasn't sure if that was eye to eye or OAL. I'll be getting a set of these I think. That measurement should keep my coils snug enough at full droop.

With shocks, I've only known the eye-to-eye to be the advertised measurement since that's the functional dimension.

You have shock extenders?

Yes sir. Now today I felt it bottom out on the r/r for the first time going through a dip in a driveway entrance. The factory length shocks I have on it right now are 24" at full droop, not sure what the compressed length is on these. I plan to figure that out over the weekend and look at the panhard and sway bar for any contact marks.

We have right about the same drop so we should have the same suspension clearance issues and should need the same mods. You've seen my thread so you should know where all to look for the contact points.

Looks like the factory type shock is around 24" extended and 14.75" compressed. So that's a 9.25" stroke.

With a 5" drop and 2" extenders, the shock "sees" a 3" drop (disregarding the arc radians to keep the napkin math cleaner). So, to maintain factory ROM, you'd need a shock 3" shorter than stock. 24 - 3 = 21. That BT 2410FF is 3.5" shorter at 20.5", so, it'd reduce the droop from the factory geometry by .5".
