250r rear end. probably has 250r brake caliper OR some home brew stuff swinger KINDA looks like a lsr but the welds and rear carrier fitment is deff not their high quality. the 250r and banshee carrer have about a 1/8 differnce in the mount location ( if i rember right) most time its not bad it might eat sprokets a lil bit.
i have one of these 250r rear ends. the r axle is much bigger but heavy. i DO like that the R has a cooler rear brake mount, axle nut on them looks not as clutter'd up like the banshee double nut stuff.
