Would be interesting to know your uni to uni centers (shaft length) as compared against similar stock build set up. Your current lengths may actually be near original build state. Maybe someone with unmodified coils (close to stock build spec) could measure their uni to uni center length and we could determine the change.
It is not so much the torque having an adverse impact, possible concern is the side loading on bearings due to the unsupported increased length, thinking mainly any out of balance in shaft. Maybe over thinking it.
Recently modified my old chains to fit the 31.5"(for GU), that I use to run on my 76 FJ45 SWB and of course guard clearance was never concern. Out with the highlift jack, up all corners (one at a time) hook on and on your way. So good. Now with the 33's not a chance, comes so close full lock..Very disappointing.
