Im askin this over in the 40/55 forum too.. but being we are 55 only I would like to ask it here too... What is the best mod/upgrade you have done on your pig? Best bang for the buck? Cheapest or free? For me it is: (1) taking the 90degree angle zerk fittings off the tierod ends when going to a larger tire and replacing them with the shorter regular zerks.(free) (2) Upgrading the stock ignition coil to an MSD Blaster 2. (35 bucks) (3) Replacing headlamps with Sylvania Xtravisions (28 bucks) (4) Dynamat Xtreme (ya it cost a bunch but works great.) (I am currently testing the PeelandSeal from Lowes) (5) Reflectix (as you might remember I have only tried this recently for heat deflection and it works awesome) (20bucks) (6) Anything I take apart using bolts/nuts gets antiseize (1 buck a tube) Im sure there is more... just cant think of anything else right now.
