• This kit features tapered rear blocks as well as angled shims. both serving the purpose of correcting pinion angle after the lift. because trucks differ form one another, in some cases it may take more than the built-in block taper to correct pinion angle. that's where the optional angled shims come in to help resolve the matter.
