Torsion Bar Set – Porsche 924/944 (31mm Rate – Tubular)
SKU 1231T
Category: Porsche Torsion Bars
The absolute peak of the "long bar" tubular lineup. These 31mm tubular rear torsion bars are engineered for professional-grade Porsche 924 and 944 competition builds. By using a hollow core, they provide the massive spring rate of a solid 31mm bar while shedding approximately 5 lbs of unsprung weight—allowing your dampers to react with surgical precision to track imperfections.
Performance & Fitment
Application: Rear Torsion Bar Set (Tubular/Hollow)
Length: 26 9/16" (Long-Bar Configuration)
Diameter: 31mm (Ultimate Competition / Maximum Weight Savings)
Porsche 924: All models (Verify spline count)
Porsche 944: All models including Turbo (951) and S2
Premium Construction
Material: Tubular aircraft-grade alloy steel for the highest available strength-to-weight ratio.
Manufacturing: Centerless ground to ensure perfectly uniform wall thickness, resulting in a precise and predictable linear spring rate.
Heat Treatment: Through-hardened and shot-peened to maximize fatigue life and prevent ride-height "settling" under extreme racing loads.
Finish: Industrial-grade powder coating for long-term protection against track debris and corrosion.
⚠️ Critical Fitment & Safety Warnings
This is a specialized racing component. Please verify the following before installation:
❌ Extreme Rigidity: A 31mm spring rate is over 290% stiffer than a factory 22mm bar. This setup is strictly for dedicated track vehicles or professional-grade competition. It will be punishingly stiff for street use.
❌ Advanced Damping Required: You must pair these with race-valved, high-pressure gas shocks (e.g., Bilstein Cup or Koni Race). Standard street shocks cannot control the high rebound energy of a 31mm bar, which can lead to dangerous "pogo" handling.
❌ Chassis Reinforcement: Due to the massive torque these bars exert on the rear suspension carrier, we highly recommend inspecting and reinforcing your torsion housing and using heavy-duty spring plates.
