Dobinson springs and 5100s vs Dobinson springs and shocks

[Nickademus78]

With the intention of only swapping the rear coils, my lower left bushing seized up on the 5100. Finally broke it loose with an air chisel. Changed the coils from 505 to 327s. Reinstalled the 5100s and went home and ordered the IMS shocks front and rear. Installed the rears and it has an amazing ride. Eventually I’ll get to the fronts. Had the 5100 and coils installed since March of 2018 and still performed well for me on the quick off ramps and at the beach. I feel the IMS is an upgrade in ride quality. Hope so for the sake of the price and size!

I've seen guys run all different Dobinsons coils on the 5100's, but always at the lowest clip height. I think that's the main thing, you don't want to add preload to them. I've also seen the bases snap on them if too heavy of a coil is added. You won't break the coils, but you could end up ruining the struts.

And as an FYI, Bilstein only recommends stock/OE coils on their struts, or coils they provide, otherwise they don't provide any warranty with them from what I've seen in their documentation.

Hey mike, I found your post from a few years back with all the good info on Dobinsons. Thanks for that! I have a quick question.

Is this C59-302 a typo? It has a shorter coil with the same spring rate as 314 but says it handles more weight?

Nope.

With more weight on it, the lift height is reduced. 2.5" with no weight, 2" with 110LBS on it

how have you like the dobinson shocks? I'm looking to replace the bilstein 5160s in the rear with the 701 shock and keep the 6112 set up in front till i need to replace it.

I am very happy with the setup. Big upgrade from stock suspension I had been running. I am sure I would have been happy either way though. Lots of folks run the Dobinsons and like them as well.

I'm looking at doing the same thing. I do however have a front lo pro bumper and 6k winch. Did you have to replace the UCA or are you still using the OEM ones?
