If I run longer shocks in the rear, do I need to worry about the coils falling out? I looked and there seems to be nothing holding them in but tension. I am considering adding some bilstein 5100s.

 

Why?

:wabbit2:

 

More travel.

 

I was hoping for slightly more travel and a stiffer shock to reduce bottoming. I have an 01 with the rubber cones cut out. Bottoms out pretty easy but the springs aren't sagging. I would consider stiffer coils but it looks like all of them add a lot of lift, which I don't want to do.

 

If you flex the rear axle far enough, the stock coils can fall out as there is nothing to hold them in place. Either the shocks or possibly the sway bar will likely limit the droop. And for on-pavement use, unlikely you'll get into a position to let the rear axle fall that far. Off-road would be a different situation.

Also, too much longer of a shock may limit your uptravel since a longer extended length usually equates to a longer compressed length as well. Could add a limit strap or rig up some small u-bolts to hold the coil in place.

 

Yea, on that point it might make sense to just pop the springs out, set it to full compression and measure the distance between the shock mounts, then find the longest stroke shock that meets that restriction.

 

Yep, that is the basic idea of measuring for shocks, see the old ORC article link below:
