Fitment & Compatibility

Compare the actual factory spindle with DS1141 before disassembly. Standard spindle/steering-arm parts need drilling, tapping and clearance-ear removal; the 1LE option is explicitly exempt. Confirm 5 x 4.75 wheels, the stated outward hub offset and complete nominal 17-inch brake clearance.

Listed model families are Camaro, Firebird; the individual year and brake/spindle conditions remain decisive. Use the fitment table below to confirm year, model, trim and brake or suspension options.

PMB Performance brings over 20 years of parts and fitment experience. Send the vehicle details and installed brake/suspension configuration if you need help checking this package.
