The Chassis
Eleanor Mustang Chassis
TCI Stage 3 Suspension and Currie 9-Inch Rear End
This 1967 Eleanor Mustang isn't running a stock chassis under heavy modern power. Building a true Eleanor means starting with a 1967 Fastback foundation and reinforcing it with a chassis and suspension package capable of handling serious horsepower, modern braking demands, and real cornering loads — not just looking the part. Here's exactly what's underneath this Eleanor Mustang for sale.
Front Suspension
TCI Stage 3 Independent Front Suspension
The front end runs a Total Cost Involved (TCI) Stage 3 IFS, one of the most respected aftermarket front suspension platforms used in high-performance classic Mustang builds. It includes a welded-in front crossmember for added rigidity, single adjustable coil-over shocks for tunable ride and handling, 2-inch drop spindles for a lower stance, and polished stainless steel upper and lower control arms. Steering is handled through a power rack and pinion setup, which gives a far more precise, modern handling feel compared to the original 1967 steering box.
Braking System
14-Inch Wilwood Brakes, Front and Rear
Stopping power comes from 14-inch Wilwood brakes fitted at all four corners, with competition silver calipers carrying the black Wilwood logo. Using identical caliper specs front and rear means balanced, predictable braking under hard stops — something a stock 1967 Mustang braking system was never designed to handle at this power level.
Rear Suspension and Differential Currie
Nodular 9-Inch with Torque Arm Setup
The rear suspension uses a torque arm design with polished stainless lower control arms and a panhard bar to control lateral movement under power. The differential is a Currie Nodular 9-inch Ford rear end, fitted with Tru Trac posi, a 3.70 gear ratio, and 35-spline axles built specifically to handle the torque coming from the supercharged 427 engine without breaking down under repeated hard launches.
Chassis Reinforcement X-Brace Subframe with Driveshaft Hoop
Front and rear are tied together through an X-brace style subframe, which supports the torque arm crossmember and significantly reduces chassis flex under hard acceleration and cornering. A driveshaft hoop is also built into the design as a safety measure, a standard requirement for cars producing this level of horsepower.

Why Chassis Quality Matters When Buying an Eleanor Mustang
A lot of people searching for an Eleanor Mustang focus only on horsepower numbers and paint quality, but the chassis is what actually determines whether a build is safe and capable at real-world speeds, or just a show car. Builders working on Eleanor-style projects generally upgrade three core areas to handle modern power: frame connectors that tie the front and rear rails together to stop chassis flex, a modern front suspension with tubular components and rack-and-pinion steering in place of the factory setup, and a stronger rear end usually a heavy-duty 9-inch Ford differential paired with upgraded disc brakes. This car was built around exactly that philosophy, using a TCI Stage 3 front end and a Currie Nodular 9-inch rear, rather than relying on the factory-spec components a stock 1967 Mustang shipped with.
The chassis was engineered alongside the rest of the build to work as one system for the full story on how the body and paint were finished, see the Eleanor Mustang bodywork and paint process, and for documentation backing every claim on this page, visit the provenance and authenticity page.
