OK, I got those LST2 shocks in the mail, and man they are big! They look good on the XT8, but getting them to work will require some pretty major mods to the rear shock tower. I'd like to avoid that if possible, so I'm gonna look for some other alternatives.
Here is a pic of some of the shocks I have for comparison:
From left to right: XT8 front shock, 808 front/rear shock, Mugen MBX5 rear shock (same length as the XT8 rear shocks), and an LST2 front/rear shock.
The LST2 do fit width-wise but are a tad too long without tower mods. If I compress them to fit, I lose the travel I want (max suspension travel as this is mostly for bashing).
So, the search continues. I'm looking for bore size like the 808 shocks (or larger), have hole-to-hole length 140-145mm, and have shock travel of around 40-45mm.
