Performance & Fitment

• • Application: Transaxle-era Alfa Romeo models (Milano/Type 162, GTV6/Type 116, and Alfetta chassis).

  • Outer Diameter: 1.417". This enlarged profile delivers an aggressive, race-oriented spring rate to minimize body roll and nose dive under hard braking.

  • Length: 38.937" (Exact factory longitudinal length fitment for applicable platforms).

  • Spline Configuration: 34/35 Tooth Vernier Spline. Features a 34-tooth count on one end and a 35-tooth count on the opposite end, preserving the legendary factory indexing layout for ultra-fine height tuning.

  • Design: Tubular (Hollow) Construction. Engineered to save substantial weight compared to massive solid bars, maintaining a high power-to-weight ratio while delivering the exact structural stiffness required.

Premium Construction

• • Material: High-Strength Alloy Steel. Forged from premium racing-grade steel designed to handle continuous structural twisting without sagging or losing its spring memory over time.

  • Manufacturing Process: Centerless Ground. The outer body of the tube is ground to a mirror finish, maintaining absolute diameter consistency. This precision removing of all microscopic surface imperfections eliminates potential "stress risers" where fractures typically form.

  • Coating: Heavy-Duty Powder Coating. Seals the raw steel against road moisture, oil, and debris, ensuring long-term protection against corrosive pitting.

🇮🇹 Alfa Romeo Suspension Tech & Installation Notes

Upgrading to large-diameter tubular torsion bars on an Alfa Romeo requires precision clocking and setup to guarantee maximum handling gains:

• ❌ The Tubular Weight Advantage: Torsional stress in a spring is carried almost entirely on the outer perimeter of the shaft. By removing the "dead" metal from the center of the bar, this tubular design delivers the massive roll resistance of a 1.417" solid bar with only a fraction of the weight, improving overall chassis balance.

• ❌ Mastering the 34/35 Tooth Vernier Spline: The unequal tooth count (34 splines on one end, 35 on the other) functions as an ultra-precise mechanical adjustment system. Rotating the bar one notch in the lower control arm socket while rotating the rear crossmember adjuster one notch in the opposite direction allows you to change the ride height in minuscule fractions of an inch, making it easy to achieve perfect corner-balancing.

• ❌ Clean the Spline Receivers: Before sliding the new 1.417" bars into place, thoroughly clean out the splined sockets in both the front lower control arms and the rear chassis crossmember. Decades of old grease, road grit, and rust can jam the splines. A stiff wire brush and penetrating oil are mandatory to prevent stripping the splines during insertion.

• ❌ Anti-Seize and Lubrication: Always apply a generous coat of heavy-duty, waterproof anti-seize or a moly-based grease to both splined ends before installation. Because these splines must allow for slight movement as the lower control arm moves through its suspension arc, running them dry will cause severe squeaking, internal corrosion, and eventual seizure.

• ❌ Maintain Directional Orientation: High-performance torsion bars are pre-stressed during manufacturing or take a specific "set" during their first heat cycles under load. Look for "Left" and "Right" markings on the ends of the bars. Swapping the sides will force the steel grain to untwist against its structural set, which can result in rapid bar sagging or catastrophic snapping under hard braking.
