Gary,Don’t the wheel spaces kind of defeat the purpose of going with a 50” ATV? is there a 1” spacer?
Yes, 1" spacers are common. You can find 1 1/2" and 2" spacers too. Any modification done is for personal choice. 50" wide is essential for me where I ride. Adding the lift kit and larger wheels, I needed to add some width to offset the change in the center of gravity.
Plus the front wheels rubbed on my MavT in front with the over sized 30" wheels, so I added 1" spacers at first. Still rubbing with 1" spacers, I ordered the 2" spacers and now I have no issues. Yes, my ride is now 56" wide, not 50". I can still get through the restriction gates where I ride. Works for me. Not saying you have to do this but just sharing my modifications and why I did them.
