Aftermarket portals require a special spindle nut, if you are running portals and purchase axles from us you will need these portal nuts. there are different nuts for different brand portals it would be best to order by phone to discuss and make certain you get the correct parts.
If you already have RCV axles, then your inner cups can be changed to be compatible for this setup, available from RCV direct. Otherwise you will need to buy complete set of axles for this differential.
We have one of the best warranties on the market. There is a 1 year warranty on anything Halo locker. We do retain the factory style ring and pinion, and we will replace anything Halo related in the diff. Anything Halo makes is covered 1oo percent.
