You can the 1.375 without iusess. I like the Iceripper with this setup.

Have done a 121 to 144 with a ZX2 on my RTX 2008, Cobra track with 34 mm lugs and no studs. Muffin works tunnel extension in black paint. I have no room for any higher lugs due to the ZX2 and the MCX rear mount. Still snow in Sweden

I did a Tracks USA 136" on my '08 RTX. This involved milling my own rail reinforcement gussets that I believe are not necessary with the Muffin Works set up.
