TRZ Motorsports S550 Solid Axle Conversion Package – ditch the factory IRS on your 2015+ Mustang for a fabricated 9″ solid axle setup built for the drag strip. This is the rear suspension we run on Bad Bish.
What's included
- Fabricated chromoly 9″ housing with multi-hole upper and lower control arm mounts, back brace, lower brace and coil-over brackets
- 3.5″ axle tubes with 7/16″ face plate – accepts 9″, 9.5″ or 10″ ring gears
- Chromoly locating cradle / crossmember that bolts to the factory frame, with multi-hole UCA and LCA mounts
- Double-adjustable chromoly upper and lower control arms with LH/RH chromoly rod ends
- Hardware
Not included
- Housing internals (axles, center section), brakes, coil-overs and anti-roll bar – we can quote these, call us
- Upper coil-over crossmember (must be fabricated in the car)
Important fitment notes
- The cradle bolts in to locate only. Both upper and lower torque box locations must be tied into your roll cage.
- Designed for cars with a rear lower crossmember (25.5-style chassis minimum).
- Will not use the stock shocks / coil-over location, stock driveshaft, or your current IRS brakes.
- Every housing is custom built to length and housing ends based on your wheels, backspacing and brakes – not a stocking item.
