5100 or 5125 rears?

Yeah I know I know another 5100 question. I searched but was not successful...

I am looking for opinions and experiences on how the 5100 rears compare to similar length 5125 rears. I know the 5125s allow for about an inch more of compression but what about ride characteristics? I had the 5125 rears on another Taco and found the dampening to be a little soft if I had any weight in the back. Please weigh in with thoughts.

 

Were the rear springs on the other Taco OE or something upgraded?

 

3" All-Pro leafpack. They were not the expo packs.

 

You'll need the Bilsteins with 9.25" travel. Don't know the part number. The only difference between the two is the length. 5100's have fixed dimensions while 5125's can be anywhere from 8-16", or something similar.

I have them now on the same springs and they do feel under damped. Actually I would say the spring is over sprung, even though it's just the standard leaf. Very stiff ride thus far, only had them on 4 months. Unloaded Tacoma.

 

The shocks referred to as 5100s have the same valving as those labeled 5125s.

5100s are made by Bilstein for RCD and come in one length only. Bilstein offers a number of different shocks (varying lengths) under the 5125 name. Almost all have a designated valving of 255/70 the same as RCD 5100s.

There are some 5125s offered that are designed for a dual shock configuration which have a lighter valving becasue they are meant to share dampening duties with another shock.

 

Any idea why the extended length is virtually the same but the compressed length differs?

I found the dimensions for both at Wheelers.

 

Here is more information on all of the 5125 versions available.
