Overview
The Baer Brakes 4262108 is an Ironsport rear disc brake kit for Ford 9 inch rear ends with Torino bearing axle flanges and five lug wheels on 5×4.50 and 5×4.75 bolt circles. It converts the rear axle to a vented, slotted and drilled zinc-plated rotor with a single-piston floating caliper. The kit is set up for non-staggered rear shocks.
Owners looking for a Torino bearing rear brake upgrade get a complete caliper package, with the park brake built into the caliper. The IronSport is a full feature drum to disc conversion and fits some 15 inch wheels and most 16 inch or larger wheels.
Key features
- Single-piston floating caliper with a silver zinc-plated finish
- Integral park brake inside the caliper
- Vented rotor with a slotted, drilled and zinc-plated surface, 11.65 Inch outside diameter
- Steel braided hoses, DOT approved
- Five lug pattern on 5×4.50/5×4.75 bolt circles
- Minimum wheel diameter of 15.0 Inch
Non-staggered shock setup
Rear shock configuration affects how the axle moves under braking, so it is worth looking at the shocks before a rear disc upgrade. Non-staggered shocks sit at the same position on each side, which keeps the rear end balanced under load. Rotor and caliper clearance can change slightly with different shock mounts, so check spacing on both sides.
Torino bearing axles arrange the rear brake hardware differently from small bearing flanges, so keep the axle identification in mind when comparing parts. Heavy use on rough roads can loosen shock and brake mounts, which makes periodic torque checks sensible. Keep brake lines clear of suspension travel.
- Measure caliper clearance on both sides
- Inspect shock bushings for wear
- Check brake line routing through full suspension travel
- Recheck mounting bolts after the first drives

Vehicle fitment
Its fit is defined by the Ford 9 Inch Torino/Late Big Bearing axle flange, 5 on 4.5 and 5 on 4.75 bolt circles and non-staggered rear shocks, so those details are the basis for checking fit.
It is built for the Torino bearing flange rather than small bearing flanges. Compare template V107I with your intended wheel first, since not every wheel style is assured to fit. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The park brake is built into the caliper, but park brake cables are not included, so confirm how the parking brake will be actuated before mounting. Check the rear shock setup against the non-staggered configuration before starting the job. Rear brake work involves hydraulic lines and should be done by a qualified installer.
What’s included
The IronSport system includes calipers, rotors, brackets, hardware, braided brake hoses and fittings.
Not included: Park brake cables.
