Whatever you decide. you dont need 3" harnesses . they are more for high speed drag cars,baja rigs, or anything really
fast.
The 2" are more than enough .
Get the shoulder straps sewn into the lap belt FOR SURE, SOOO much easier IN & OUT.
Padded shoulder straps.
The 2" wont rub your neck as bad either.
if you want the most convieniant style, it would be as described above with the cam lock style latch.
But not if you run in mud , if you do the mud, then get the normal flip latch style.
Think about it , all cars have THIN 2" belts. Have you ever heard of them breaking ?
The 2" harnesses are twice as thick as factory automotive belts.
3" are way overkill , harder to deal with buckleing up and worse on the neck rubbing .
