Pontiac V8 1970-1981 Firebird/Trans Am 2nd Gen F-Body
Order By Year — 1970-1981 Firebird/Trans Am 2nd Gen F-Body for Pontiac V8s
Parts for the 2nd Gen Firebird and Trans Am split by year more often than owners expect, and subframe connectors are the clearest example: 1970-73 and 1974-81 cars take different pieces. Check the build year before ordering anything for this chassis, not the decade.
Butler lists connectors covering both halves of the run, including a Butler Performance set that fits the whole 70-81 span, alongside the RideTech StreetGRIP, coil-over and air systems that belong on a chassis once it has been stiffened.

More About 1970-1981 Firebird/Trans Am 2nd Gen F-Body
1. Connectors, and which set is yours
A second-gen body flexes between the front subframe and the rear leaf spring mounts. Both sets below address that, and neither requires fabrication.
| Butler Performance 70-81 set | the PTFB connectors, covering the entire second-generation run in one part number. They can go on bolted or welded, arrive powder coated, and ship with solid body bushings offering standard height, a 1/2" drop or a wedged position. A good answer on T-top cars, where the roof is doing none of the structural work. |
| RideTech connectors | year-specific, one version for 1970-73 and another for 1974-81. Heavy rectangular steel tube, satin black finish, hardware in the box, and they play nicely with original leaf springs, with StreetGRIP composite leafs, and with RideTech's current 4-link. |
2. What goes on afterward
With the chassis tied together, the rest of the catalog for this car does what it claims.
| StreetGRIP | keeps the stock suspension architecture and upgrades every piece of it, including composite rear leaf springs and rebound-adjustable shocks. |
| Coil-over and air systems | both carry the TruTurn front package and the bolt-on rear 4-link, which between them take the vague steering and axle hop out of a second-gen. |
One ordering note that applies across all of it: RideTech sets front spring rates for a cast iron head Pontiac V8. Running aluminum heads or an aftermarket block, tell us in the notes so the spring matches the weight the car actually carries.
