Choosing correct size for bumpstops?

My TC Klines just came back from rebuild (they were spares and did not have any bump stops with them) and they included the foam type ones when they sent them back. However, they look MASSIVE. The front shocks were shortened (springs are .8" drop) and the bump stops seem to take up the whole shaft.
My question is, how do I measure the amount to take off or is there a general rule of them? I know these are too big but I'm not sure how to determine the proper amount to cut off OR if I should just purchase progressive ones. If so, which length? If it matters the spring rates are 690lbs.

Bump stop is a matter of suspension compression travel limit and the compressed length of the damper. In your specific case, where are they ? Is the damper shown positioned at full length ?

Due to the shaft or the large bumpstop? I'm assuming they just threw generic ones on as all four dampners share the same size bump stop. The shocks were shortened to compensate for the drop, but I have no idea how to properly size the bump stops. Or if such formula or theory exists...

Install shock without spring or bumpstops , install zip tie on shock shaft , install tire , compress suspension it bottoms or tire bottoms. Measure and decide how big of a stop is required. Very simple, also the foam stops are made it increase usable spring rate as they engage. The ones I run I like 120lb , they engage 3/4 of an inch before I want the suspension to stop. Kinda cool, it's like a progressive system.

When I get home in the morning I will measue the fronts/rears and get you that info.

That is correct. Or stop the travel before that point so hard parts don't hit. My car , I had to limit front travel a little more than my previous setup to keep my splitter from hitting the ground.
