This set of axles has only one problem, they do not come with the ABS ring on them. thats all !(the ABS ring comes righ off tha factory axle very easy) in fact if you have a 2009-2010 car and want the very best and strongest axle this is it second to none. This axle is designed for a real race car that just happens to be street driven. we have started with an outer CV that is made from solid billet material that is stronger than any of the Aerospace materials on the market today, we have completely custom made REM polished internals out of that same material and just to make sure this is the strongest axle we have increased the center bar's diameter by 25%. To cover the inner CV we have developed a modified Porsche style CV that we have put the same REM polished high grade internals with that same big spline/ We went on to make a real nice billet flange to stick into the Getrag diff. so you can either hope the lesser axles out there dont leave you stranded or you can just purchase the very best axle made for the car, its simpleWarranty: 1-year| Special Notes: must re-use factory Tone/ABS ring This kit includes both axles.
