Protofab Corvette rece prepped for the Dallas Grand Prix You can’t find a better rear spindle than what we offer. These are drop forged and produced to the exact appearance and dimensional specifications, but with superior metallurgy to the original part. As you know, the rear spindle / bearing assembly has been the Achilles heel of these C-2 and C-3 Corvettes. The design was ahead of the materials. Now the materials have caught up. By the way, in case you are wondering why we should show a C-4 Corvette on our 63-82 Corvette website; its is actually the same 80 Corvette pictured on the top of the 80-82 Diff page. We rebodied it in 1988 to run the car in the Dallas Grand Prix Trans Am race. We finished 7th.

1965-82 new Corvette replacement trailing arm assemblies65-82 New Replacement Trailing Arm Assemblies

These are the same assemblies as the T010, but without the riveted rotor. GM replacement rotors have no rivet holes. The riveted rotors were a factory only deal, and the wheel studs hold everything together anyway. These assemblies have new trailing arms, bushings, spindles, bearings, seals, backing plates and stainless steel parking brake parts. They are greased, torqued and ready to install in your Corvette.

1965-79 refurbished trailing arm assemblies65-79 Refurbished Trailing Arm Assemblies

These assemblies are set up to the same close tolerances as our new units. The only difference between this part and part # T020 is with this assembly we use a reconditioned GM trailing arm and spindle. The trailing arm bushing, backing plate, parking brake parts, bearings and seals are all new.

There is no core charge, but if you want to get rid of your old parts, put them our box and send them back to us. We will send you a check after we figure out what is reusable. Check the Cores Page. If we can reuse your trailing arm and spindle, your old assembly is probably worth $150. - Specify Left or Right - Free Freight

* Note: These require assembly in our shop and require more time.

Note for T027: We don't believe in re-using 30 year old spindles. We trash 75 percent of those that we get in as cores, but even the ones we keep to be used in the T026 assemblies are still 30 years old. They were originally designed for tires that had 4-1/2 inches of tread on the ground. Now the tire patch is twice that. For our money, we would opt for a new spindle. - Free Freight
