Torsion Bar Set - '65-'89 Porsche 911/912/930 and VW Bug (30mm/Solid)
SKU 1130
Category: Porsche & Volkswagen Torsion Bars
The absolute maximum in rear-end rigidity. These 30mm solid rear torsion bars are the stiffest non-tubular bars available for this fitment, specifically engineered for ultra-high-horsepower competition builds, heavy V8-conversion sand rails, or professional drag racing where eliminating rear-end "squat" is the primary goal.
Performance & Fitment
Application: Rear Torsion Bar Set
Length: 24 11/16”
Diameter: 30mm (Extreme-Duty / Race Only)
Premium Construction
Material: Solid aircraft-grade alloy steel for maximum torsional load capacity.
Manufacturing: Centerless ground to ensure a perfectly consistent diameter and a precise, linear spring rate across the entire bar.
Heat Treatment: Specialized through-hardening and shot-peening to resist fatigue under extreme racing conditions and prevent suspension sagging.
Finish: Industrial-grade powder coating for superior protection against corrosion, impact, and road debris.
⚠️ Critical Fitment Exceptions
Even if your vehicle falls into the year ranges above, you must verify it does not meet these specific exceptions:
❌ G50 Transmission Porsche 911: This SKU will NOT fit 1987–1989 Porsche 911 models equipped with the G50 transaxle. Those vehicles require significantly longer bars and a different spline count.
❌ Post-1959 VW Beetle: These are the "short" 24 11/16" bars. They are incompatible with 1960–1968 Swing Axle models (26 11/16" bars) or 1969+ IRS models (21 3/4" bars).
❌ Maximum Stiffness Warning: A 30mm spring rate is over 250% stiffer than a factory 22mm bar. This results in an incredibly rigid ride that is not suitable for daily street use.
❌ Chassis Reinforcement Required: Due to the massive torque these bars exert, we highly recommend using reinforced spring plates and checking your torsion housing for structural integrity.
