Bilstein 5100 shocks for 3"-3.5" rear block!

pewterliftedz · July 17, 2018

I'm currently running a 2.5" rear block in place of the factory 1.25" to keep some rake with my leveling kit. I will be installing the Superlift 3.5" kit in the coming weeks, and want to install a 3" or 3.5" rear block to maintain some rake; also planning to install a set of 5100's at the same time. I know bilstein offers the 5160 shock that will work with 0-2" rear lift, but I personally don't have the need for a remote reservoir.

So I went searching for a shock that had similar dimensions to the 5160, and I found the 2012 Dodge Ram shock, part# 24-187374.

Silverado 5100 #33-238319

Collapsed Length (IN) - 16.18
Extended Length (IN) - 25.79

Silverado 5160 #25-242515

Collapsed Length (IN) - 16.14
Extended Length (IN) - 26.81

Dodge 5100 #24-187374

Collapsed Length (IN): 16.75

Extended Length (IN): 26.73

I'm probably going to order a pair to try it out.

Another option is to use the regular 5100 that accommodates a 1" lift and add shock extensions. I have them because I swapped the 1.25" stock block for a 3".

The extensions I bought are very heavy duty, not a flimsy piece of junk.

I like doing it this way because I can use my stock shocks or my Bilsteins.. Or go back to stock height if I want and use any shock I want.

Right now I have Bilsteins in front and stock in rear. Seems to give the best ride on my 2015 NHT.
