I have a 2003 Cobra IRS with a Billetflow brace. I blew the housing on the last irs at 24,000 and it has all new gears, housing, bearings, and shafts. IRS since then has 7,000 miles on it. Have not done any burnouts on it and have not had wheel hop in it for fear of blowing another one. Looking for a built solid axle to trade and some money for or any complete solid axle from caliper to caliper. Email me at [email protected] or let me know. I live by st.louis.
