If you’re building a 1965–1979 Ford F-100 or F-250, you already know the story: great-looking trucks, rock-solid drivetrains, and plenty of vintage charm—but saddled with a front suspension that’s… less than ideal. For decades, Ford’s Twin I-Beam system has made stance, handling, and steering upgrades a challenge. Until now.
Classic Performance Products (CPP) has changed the game with a fully bolt-in Mustang II Independent Front Suspension kit designed specifically for these trucks. Whether your goal is a smoother ride, sharper steering, a better stance, or the full pro-touring treatment, this kit delivers a modern driving experience without cutting up your frame.
Let’s break down why this bolt-in solution is such a big deal.
A Quick Look Back: The Twin I-Beam Era
Ford’s fourth-generation F-Series (1961–66) offered fresh sheetmetal updates every year, but the chassis remained mostly untouched—right up until mid-1965 when Ford launched the now-famous (and sometimes infamous) Twin I-Beam front suspension. The idea was clever: two long I-beam axles, each pivoting on opposite sides of the frame, allowing independent movement while keeping traditional axle strength.
While it sounded great on paper, the design carried over well into the next two generations—1967–72 and 1973–79—and brought some challenges:
- Minimal caster resulted in poor straight-line stability
- Camber change caused wandering and uneven tire wear
- Harsh geometry meant shocks wore out quickly
- And worst of all... these trucks were very hard to lower correctly
The trucks themselves stayed affordable and desirable—especially compared to skyrocketing C10 prices—but suspension limitations kept many builders away.
The Modern Solution: CPP’s Bolt-On Mustang II Front Suspension
CPP’s fully bolt-in Mustang II Front Suspension Kit flips the script for these classic Fords. For the first time, builders can ditch the Twin I-Beam and gain true independent suspension without major fabrication.
Why Mustang II?
The Mustang II may not be remembered for its performance, but its front suspension is legendary:
- Strong wheel bearings
- Full-size Ford-sized ball joints and tie-rod ends
- Compact geometry with excellent engine clearance
- Rack-and-pinion steering for modern road feel
- Highly adaptable to custom builds
It remains one of the most trusted IFS systems for classic trucks and street rods alike.
Bolt-In Installation—No Welding Needed
CPP designed their kit to be installer-friendly from the ground up.
After removing the factory I-Beams, brackets, and crossmember, the CPP crossmember and upper control arm brackets bolt right into the factory holes for perfect alignment. Only six new holes need to be drilled—no welding, cutting, or complicated fabrication required.
This means home builders can tackle the upgrade confidently, and shops can complete the install quickly and consistently.
