jaydeer 14 #1 Posted June 7, 2012 COuld anyone tell me what rear ends would fit in a 520 8 speed? Someone stopped for a 520 rearend, which I had in a hydro, but his was a 520-8. I was not sure if the axle was longer thatn a typical 8 speed. Any help would be appreciated. Share this post Link to post Share on other sites
can whlvr 993 #2 Posted June 9, 2012 so i looked up a 41-20o801 which is the 520 model and compared some parts like axle,some gears to my 1989 414-8,it has the same rear end,which gives lots of options,all 400 series 8 speeds,maybe some of the later 300 series with the 1 1/8 axle,these will be a direct bolt in,but maybe some older c series would work too,but i have not done it so the shifters might be a little diferent but may work also,hopefully someone has put a c in one,but there werent too mant 520-8 made,and they are relatively new so i wouldnt think too many of them would need new rears,but the 400 series will work and theres lots of them around Share this post Link to post Share on other sites
