if i already have a trutrac (to install) and 4.10s installed to i have to have an install kit to do the job?

 

The "HD" style bearings are for 1998-older 8.5 rearends with aftermarket large journal carriers. Your 2001 will use the 8.6 kit. We do not have the coated axles. We sell the bearings and seals for $60.00/pair.

Thanks, Ron

 

If you have the adjustable shims and can remove the bearings you should be all set. If not, you will need a carrier install kit.
