Strong! Compact! Unlimited Gear Ratios!
Ultimate IRS 8.8 Iron Case
The "t-bird" style 8.8 case has a few distinct advantages over all the other 8.8 cases. It's the strongest, its the most compact, and it has more gear options than pretty much anything other than a 9".
This IRS specific case was developed due to a lack of availability of these cases at junkyards. These same style cases were found in 1989-1997 Ford Thunderbirds.
These reproduction cast iron cases are precision machined on a 5-axis CNC to the tightest tolerances possible. These come with billet main caps and studs. Ready to be built however you want it, or I do offer complete built differentials with this case.
