Thought I answered but, guess some electronic gremlin eveidently 'ate' it.

Yes, it will not only lower the trailer a bit but will pull the wheels closer. This in turn may change the stability and cause a 'twitchiness' when towing. My frame of reference was when I replaced the springs on our 343RL High Country with 26" versions instead of the required 25-1/4". A note here - you said yours were measured in place at 26". They probably are in reality, 25-1/4 in a free, uninstalled free state. I made that $150 and 5 or so hours labor mistake. Be real carefull with the on line Dexter charts - they contributed to my $$ mistake.
