So I didnt like my old 52's (to heavy, to many leaves, sat to flat). So I got these, I am thinking they are dodge 52's. But they have some weird things.... First of all they ARE 52's, BUT they have a offset center pin. The offset is 2" over regular 52's. So if I put them in, it will either push my axle back to stock or push it another 2" forward giving my 4" total over stock. BUT it would be cool because it will make my approach angle even better. NEXT is the spring eyes. On one end it is normal just like normal 52's. On the other end the spring is wrapped around the TOP of the spring eye. Know I thought this would be cool because it would give a better pinion angle but with the offset center pin it will prolly be like normal 52's. SO explain this one you spring experts. It is a 4 leaf pack, same width as normal 52's. they are really soft but compared to my old pack they have more arch.
