1967 - 1969 Firebird Speed Tech Complete Heavy Duty Dutchman 9" Rear Differential

The next step to your rear suspension upgrade and perfect match for our Torque Arm Suspension System is a new heavy duty rear axle. These 9" Ford axles for '67, 68 and 69 Firebirds are stronger than stock and include a Trutrac center section, heavy duty gears in your choice of ratio, 31 spline axle shafts, and all new bearings. Standard on all rear axle packages are 9" Ford style housing ends for easy brake package selection and eliminating c-clips on the 12 bolts. Our axle packages have our Torque Arm brackets jig welded on for a direct bolt-in fit. Ford 9" housings are also available without 3rd members. All axles come raw finish.

Assembly Tip: Gear Oil, Additive and Break-In
Use a gasket or 100% silicone to seal the cover or third member to the housing. Use only high quality name brand gear oil and fill the differential until the oil spills out the plug hole. Positraction carriers require anti-friction additive. All new gear sets require a break-in period to prevent damage from overheating. After driving the first 15 or 20 miles you must let the differential cool for 30-40 minutes before proceeding. Drive 500 easy miles. Change the gear oil after those first 500 miles. This will remove any metal particles or phosphorus coating that has come from the new gear set. Any overloading or overheating can cause the gear oil to breakdown and the Ring & Pinion can fail.

IMPORTANT: Please Specify your gear ratio in the order notes!

Note: Rear Diff is not painted, raw material
