Rear Shocks

MunichDave · Jun 29, 2024

Hello everyone, I have a question on rear shocks. I replaced my stock rear shocks with the Bilstein part number 24-187374.
I love the shocks as they ride and handle great! The issue I am having is the shocks must be a lot longer because now every time the truck is put on the lift my rear springs fall out of place. I didn't notice this until recently and I don't have the stock rear shocks to measure. Has anyone had a similar issue with this??? Would anyone be able to tell me the full extended length on the stock rear shocks?
I don't want to have to worry about my spring falling out of place every time it's put on the lift.
Thank you for any and all help. I appreciate it.

I don’t think the shock is strong enough to push it up. It should still sag regardless. you can probably put spring spacers in there to make up the difference. I’m sure they probably make whatever size you need just measure what gap you have.

What I found in another post on this forum is the stock shocks are 25.5 inches, measured center to center of the upper and lower shock bolt holes.

Is it possible that was not the part # that way installed and what sway bar endlinks do you have?

Everything on the truck is stock except the Bilstein shocks. Bilstein Part Number 24-187374 says they are 26.73 extended length.
Guys I do appreciate the help. Even my Mechanic was like why do your springs fall out of place when we put it on the lift?
All I can figure is the shocks are longer allowing the rear to drop lower than it's supposed to. ‍

I doubt it is the shocks. The springs are probably missing a bolt.
Look up the schematics for the rear shocks.

They dont get bolted in, they just get pinched between the frame mount and axle mount. Too long of shocks can definitely let the coils fall out of position when the axle is fully drooped down.

If you look at BS's description of the shocls they sell for this truck, most of them say "Lift, 0-1" unless you get longer ones. Their shocks, generally speaking, are almost always 1" longer than stock.

Would you design coils to drop out when extended?

Think about it.

I didnt design anything. Im just telling you the way it is.

The shocks limit the travel which keeps the coils in place. Otherwise they will legit just fall right out.

Just stating the facts.

If everything is stock I can only assume (without pictures) the wrong shocks were installed whether they were boxed wrong, returned etc. possibly even stickered wrong at the production level. Very rare to get a matching set of an imperfection. If you were my customer your truck would never leave the shop. We would replace the springs because progressive rate springs are way better or swap shocks to ones that work

Literally yes. When I did my front shocks a few months ago, all I had to do to get the coils out was unbolt the shock and jack it up by the frame and the coil was able to pop right out. I recently say a video of a jeep (different but same concept) doing some off roading, but he was running without shocks presumably to get extra travel. Well, he over extended, the coil popped out and he ended up riding on bump stops because the corner basically disassembled itself with no shock to hold everything together.

The shock is supposed to keep it from over extending. With shocks that are A) longer or B) not present, there's nothing to keep that coil in place when it reaches full extension.

They shouldn't drop out during any normal operation. If the springs can pop out by simply raising the vehicle on a lift they would have the chance of popping out when driving....like when off-roading and hitting a big bump or flexing out. There is generally something in the suspension that does not let the axles droop enough to completely unload the coil springs. On my 2500 the droop is limited first by the shocks, and then by the trackbar and/or swaybar. In order to get the axles to droop enough to pull the springs you have to unbolt the shocks and swaybar links. And on the front I had to unbolt the trackbar also and still had to pry down on the wheel hub to get it drooped enough to pull the spring.

I'm not one for long posts.

I installed the rear shocks myself but when I did it I never thought to check the extended length. That's got to be the reason why when it's on the lift the coils can come right out. The Springs are progressive rate springs that I installed but those were definitely the same length. Also both the shocks and springs were done at different times with the shocks being done first. I'm willing to change the shocks out to new ones but I just want to make sure I get the stock length ones. These Bilsteins ride so nice!
Thanks for your help guys!

If you like the shocks and they are working well aside from being too long and dropping coils out, you could always just get some limiting straps.
