Out with the old...
In with the new...
Put some 4th gen 5160's in to keep up with the 210v's. When sourcing these, I looked at the long travel 3rd gen 5100's and found out they were just stock length 4th gen shocks (33-187174). After that revelation it was easy to figure out that the 5160's were going to work just the same!
33-187174 ("long travel" 3rd gen/standard travel 4th gen 5100's):
Collapsed Length (IN): 14.91
Extended Length (IN): 23.5
25-227611 (4th gen standard travel 5160's)
Collapsed Length (IN) 14.83
Extended Length (IN) 23.5
The base mount is wider than the 5100's, but the bushing is a different design, so they ended up having roughly a similar gap between the mount post on the axle and bolt (~1/2"). The 5160's are perfect (so far) for these springs! Firm to the point where it got rid of most of the body roll that came with the 5100's after the sway bar deletes, but soaks up all of the road still. Can't wait to test them in the trails this weekend!
