heres my attempt to make a sticky for the xpt2 section since I already done the post for the rs1 which shares the same transmission. so here is the options for reductions. if there are corrections please PM me and Ill get them fixed

OPTION #1: A reverse shaft change of 12% across all 3 ranges- 570 gear set PN’s 3235380 27T and 3235381 46T

OPTION #2: 26% across all 3 ranges- 325 gear set PN’s 3235451 25T and 3235450 48T

OPTION #3: will reduce Low range 21%, Reverse and High have negligible change. this is simply changing the low set to a ranger set. of which would be a 3235232 67T and the 3236132 25T that are on the two piece input shafts that we have.

OPTION #4: 33% Low reduction, 12% Reverse reduction, 12% High reduction. Keep the stock shaft but swap to ranger low set 3235232 & 3236132, then add the 570 gear set 3235380 & 3235381

OPTION #5: 33% Low reduction, 12% Reverse reduction, 8% High reduction.- Start with an 18’ XPT4 input shaft PN 3235988, add the ranger low set 3235232 & 3236132, then add the 570 gear set 3235380 & 3235381. Now to clear up why the 4% difference in reverse and high, that is because the 18’ XPT4 input shaft has a 4% taller high gear and is still 2 piece so the low gear on it can be changed.

OPTION #6: 47% Low reduction, 26% Reverse reduction, 22% High reduction- Start with an 18’ XPT4 input shaft PN 3235988, add the ranger low set 3235232 & 3236132, then add the 325 gear set 3235451 & 3235450.

OPTION #7: 47% Low reduction, 26% Reverse reduction, 26% High reduction- keep the stock input shaft , add the ranger low set 3235232 & 3236132, then add the 325 gear set 3235451 & 3235450.
