thats what im doing in my 51. i thought the 5.14 was probably going to be a little bit much even though im using a over drive transmission but kept it around just encase.

i found a cab&chassis 14bolt with a 4.11 gear on craigslist for 100 bucks. 63 wms measurment which is very close to the eaton.

biggest issue i ran into is no one sells a 2 inch wide spring perch for the 14bolt axle tube. ruffstuff did have one for a 2.25 spring, i just had to grind down the sides a bit

Saw someone post making their own perch by cutting 2" square tube in half lengthwise. Try that, it was also followed by a response of finding perches for utility trailers. I haven't confirmed or followed through with any of that, but letting you know.

yeah the 2 inch square tubing was going to be the plan, but i figured trying to cut that perfect of a hole to fit on the axle was going to be a pain. i did call a few trailer/spring places and no one had any 2inch perches period.



the 2.25 wide ones from ruffstuff worked out pretty easily as i just had to take a bit of material off the sides off them, they were plenty thick
