Classic Mustangs hold a special place in automotive history, but they also came with their fair share of design flaws. Among the most dangerous? Cracked shock towers. Left unchecked, this issue can lead to serious suspension damage and even steering failure. If you’re working on a Mustang restoration project, understanding this flaw is crucial.

Common Classic Mustang Design Flaws
While classic Mustangs are undeniably iconic, they weren’t perfect. Original owners often dealt with issues such as:
- Leaking cowl vents
- Weak seatbacks prone to breaking
- Defective braking systems
- Defroster air doors that deteriorated over time
- Faulty parking brake mechanisms
- Frozen door latches
- And most notably—cracked shock towers
Cracked shock towers are more than just a nuisance. They disrupt front-end alignment, increase suspension wear, and pose serious safety risks if ignored.
Why Mustang Shock Towers Crack
The root cause lies in the suspension system design of 1965–73 Mustangs. Ford opted for a coilover upper control arm front suspension, which reduced manufacturing costs but sacrificed long-term durability. The trade-off? Weak points in the structure that eventually lead to fatigue and cracking in the shock towers.
Suspension Design Flaws That Make It Worse
One of the biggest issues was upper control arm binding. When binding occurs, the shock towers flex excessively with suspension movement. Over time, this constant stress creates metal fatigue. The result? Visible cracks that compromise both handling and safety.
The 1967–70 Mustang Shock Tower Weakness
Although all 1965–73 models were affected, the 1967–70 Mustangs are especially vulnerable. While their shock towers share the same basic design, differences in how they connect to the body—and unique apron configurations—made them more prone to structural stress.
This is why restorers and owners of these specific models should pay extra attention during inspections.
How Dynacorn Body Parts Solve the Problem
Thankfully, modern restoration body parts provide a stronger alternative. Dynacorn manufactures replacement shock towers from heavier-gauge steel, making them more durable than the factory originals.
By upgrading to Dynacorn body parts, you not only restore the classic look of your Mustang but also add long-lasting strength and safety.
Why You Should Inspect Shock Towers During Restoration
If you own—or are restoring—a 1967–70 Mustang, carefully inspect your shock towers before moving forward. Even minor cracks can spread quickly and lead to major structural issues. Replacing them early with high-quality Mustang restoration parts can save you time, money, and prevent potential accidents down the road.
Final Thoughts on Mustang Restoration Parts
Classic Mustangs may have been designed with a few flaws, but with the right restoration body parts, these iconic cars can be safer and stronger than ever. Investing in upgraded components like Dynacorn shock towers is one of the smartest moves you can make for your restoration project.
