Hiya guys,

Hey I've got some 33X12.50X15 MTR II's on MT rims, I am getting ready to install a 4.5" lift with full rear springs and 1 3/4 lift shackles and 1 3/4 lift spacers on the front. for a total of about a 6" lift. also planning on bushwacker cutouts in the future.

my question is do I need degree shims and if so what degree?

any info would be helpful, thanks
