I put in a gearvendors OD last winter , so far I have to say it was well worth it

AJ/F In my truck i used it to cure the horrible 3/4 split, that was more than 22 yrs ago. Back then there were no 4 spds to really do what we wanted and DN was the only 5spd and they weren't comfortable with what i was doing.
So it went to USgear and Gear Vendor, USg turned into a huge redesign of the driveline and GV had no concerns of 6800 lbs, hp/tq, towing, knock yourself out he told me, so i bought it installed and not a single problem.
Then i added more to the cars so having 4.8 and 5. series gears wasn't a issue on the street anymore.

Was very helpful with the hills upstate and heavy trailer and splitting gears.
