Bought a SpynTec Kit and had it installed along with new ball joints. The whole kit is top notch, very good machine work the heat treated, exposed hub parts are Stainless Steel, and all the expendable parts are stock off the shelf - - Bearings are Timpkin, Seals are Chicago Rawhide - - they even have a 'V' seal to keep crud out of the ABS system - - contact is Matt Martin at 234. 759. 3105
(I have no interest in SpynTec)
