Rear Suspension

When Zora Duntov unveiled the independent rear suspension of the 1963 Corvette, he elevated the American sports car to a world class level. That design remained virtually unchanged for the next 20 years. In the last 25 years, we have learned how to keep this design competitive with the worlds best sports cars.

 65-82 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. No Cores Required, but check out our core page for refunds on your old parts- Free Freight

 65-79 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: Allow 5 -7 business days for manufacturing 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

Offset Trailing Arm 
These arms are offset 2 inches to accommodate more than the stock 3 inch backspacing. They are powder coated and come standard with Poly Bushings. There are three places the stock tire just misses with a standard trailing arm - the arm, the frame directly over the axle centerline and the spring. Remember to figure in tire wall flex when evaluating the clearance between your tire and the sharp end of the rear leaf spring. Free Freight

Poly Trailing Arm Bushing Set
These Prothane Poly bushings are all poly, and need the metal outer shells off your old OEM bushing for a proper installation. If you have no old OEM bushings, you will need to buy a T050 OEM bushing plus this part to make things work. This bushing is for a single trailing arm.

 63-77 Standard 9-Leaf Rear Spring     
This 2 1/4 inch, nine leaf spring has the same 196 lb. spring rate as the original 9-leaf spring that was installed new in your 63-77 Corvette. It is going to feel twice as stiff as your old one when you install it, since your old spring has very likely lost 50% of its spring rate over the years. Click on the Option Button to get the original style curled up end leaves (in case you are building a car for Bloomington Gold). Free Freight

  78 - 82 Standard Rear Leaf Spring     
These springs are 2 1/2 inches wide, 9-leaf with the stock 260 lb. spring rate. Corvettes put on weight in the later years of the C3, and needed the additional spring rate. If you have a 78 Corvette, measure the width of your old spring! Chevrolet changed to the wider spring early in the model year, and this wide one won't fit your car if you have the early design spring mount. Free Freight

63 - 82 Rear Spring Bolt Kit
Here are three options for the hardware package that mounts the end of the spring to the trailing arm. The OEM set is an exact GM replacement, while the R052 set has aircraft style 7/16th inch Grade 8 bolts with lock nuts in place of the OEM style bolts with cotter pins. I recommend using the less expensive but stronger aircraft style bolts, unless you are trying to impress the NCRS. You can also get this set with Poly bushings, or with 2 inch longer spring bolts to give you some more ride height adjustment. Free Freight
