The last time I did the rebuild on my irs differential I had no problem getting right parts but now ive gotten my self a little confused as to what rebuild kit is right for the irs as there seems to be a difference with solid axle or irs. Like do all 8.8 rebuild kits fit the irs ? also there seems to be a bearing/seal kit that is only for irs? would like to stay with Ford/racing performance.
