I had a old style Locker in 1 of my old 450's and it was pure hell to ride on the trails..The new Detroit Gearless from High Lifter is great..You barely notice it being there until you get in the mud and see all 4 spinning!If you are wanting 1 to put in your Rincon though,get ready to dig deep in your pocket..I think for the Rincon they run close to $500 and you have to let them install it because the gears have to be machined in the front differential..You can put 1 of the old style Locker's in for less than $200 if you do it yourself,but if ride very many trails get the Gearless if you really have to have "True 4wd"!!
