SET OF 2, One pair is required per vehicle.
Fits:
Porsche 911: 1965 through 1989
Porsche 912: 1965 through 1969
Porsche 930 (Turbo): 1975 through 1989
Choose from the following torsion-bar rates: 19 mm, 20 mm, 21 mm, 22 mm, 23 mm or 24 mm.
The different rates allow the front suspension setup to be tailored to suit anything from a standard-style road car through to fast-road, autocross and competition applications.
Product Information
High-performance Sway-A-Way tubular front torsion bar set for classic Porsche 911 models. Designed as a direct replacement and performance upgrade for the factory front torsion bars, these bars allow you to select the spring rate that best matches the vehicle's intended use, suspension specification and handling requirements.
Unlike conventional solid torsion bars, the tubular / hollow construction is designed to achieve the required torsional spring rate while reducing unnecessary component weight. This provides an excellent strength-to-weight solution for performance-focused Porsche suspension systems.
Sway-A-Way torsion bars are manufactured from high-strength 4340 alloy steel, a material widely used where excellent fatigue resistance and strength under repeated torsional loading are required.
The bars are precision manufactured, heat treated and finished for durability, helping provide a consistent spring characteristic during demanding road and track use. Sway-A-Way product information specifies centreless-ground alloy-steel construction, heat treatment and protective coating on its Porsche torsion bars.
Choosing the Correct Torsion Bar Rate
The torsion bar acts as the spring in the classic Porsche 911 suspension system.
Increasing the torsion-bar rate increases suspension stiffness.
This can provide:
• Reduced body roll
• Sharper steering response
• Improved control during aggressive cornering
• Reduced suspension movement under load
• Better support for performance tyres
• Improved chassis response on track.
However, increasing torsion-bar stiffness also changes ride quality and the overall balance of the chassis.
19 mm
A softer option suited to cars where road comfort and near-standard suspension behaviour are priorities.
Ideal for:
• Standard or lightly modified cars
• Road use Restoration projects
• Drivers wanting compliant suspension behaviour
20 mm
A mild performance increase that offers a useful step toward sharper handling without moving too far away from road-oriented suspension characteristics.
Ideal for:
• Fast-road cars
• Uprated road suspension
• Weekend sports cars
• Mild performance builds
Installation & Performance Notes:
• Balanced Handling: When upgrading the front bars to 20mm, it is highly recommended to also upgrade the rear torsion bars to maintain the 911’s neutral handling balance. Pairing 20mm front bars with 26mm or 27mm rear bars is a common "sport" configuration.
• Indexing: These bars utilize the factory splined ends. Correct indexing (clocking) during installation is critical to achieving the proper stance. Document your original bar's orientation before removal to simplify the setup of your new ride height.
• Maintenance: Thoroughly clean the female splines in the A-arms and adjustment caps. Apply a high-quality waterproof grease to the splines during assembly to prevent future seizing and "creaking" during cornering.
21 mm
A more noticeable performance upgrade providing increased front-end support and reduced body movement.
Ideal for:
• Fast-road driving
• Autocross
• Dual road/track use
• Performance suspension builds
A 21 mm effective rate represents a substantial increase in stiffness compared with a standard 19 mm front torsion-bar rate.
Performance & Installation Notes:
• System Balance: To prevent excessive understeer, 21mm front bars should generally be paired with upgraded rear torsion bars (typically 27mm or 28mm) to keep the 911’s handling neutral.
• Damping Requirements: Because the spring rate is significantly higher than stock, standard comfort-valved shocks may be overwhelmed. Performance-valved dampers (such as Bilstein B8 or similar) are highly recommended.
• Spline Care: Always clean the female splines in the A-arms and adjustment caps before installation. Use high-quality waterproof grease on the splines to prevent future seizing and ensure quiet operation.
22 mm
A performance-focused option suitable for cars using uprated dampers, tyres and complementary rear suspension upgrades.
Ideal for:
• Aggressive fast-road use
• Track days
• Lightweight builds
Installation & Setup Notes
• Weight Benefit: The tubular design reduces unsprung mass at the front of the vehicle, allowing the suspension to react more quickly to road imperfections compared to a solid bar of the same rate.
• Spline Care: These bars feature factory-style splined ends. Ensure the female splines in the A-arms are clean and lubricated with a high-pressure waterproof grease during assembly to prevent "creaking."
• Indexing: Due to the 22mm diameter, indexing is sensitive. Document your original bar position to ensure you can accurately set your desired ride height (factory or "Euro" spec).
23 mm
A significantly stiffer option intended primarily for serious performance and competition applications.
Ideal for:
• Track cars
• Autocross
• Competition builds
• RSR-style projects
• Cars using competition-spec dampers and rear torsion bars
The 23 mm tubular version is described by X-Sway as a competition-oriented front torsion bar with substantially increased rate over a stock 19 mm setup.
Performance & Installation Notes:
• Balanced Setup: At a 23mm front rate, you must upgrade your rear torsion bars (typically to 30mm or 31mm) to maintain the 911’s handling balance. Using these with stock rear bars will result in severe understeer.
• Damping Requirements: This spring rate requires aggressive damping. We recommend competition-valved struts (such as Bilstein RSR-spec or custom-valved dampers) to prevent the front end from feeling "bouncy."
• Spline Maintenance: Clean and inspect the female splines in your A-arms and adjustment caps. Apply a high-quality waterproof grease to the splines during installation to ensure quiet operation and prevent seizing.
• Indexing: Because these bars are so stiff, indexing is extremely sensitive. A single spline adjustment will move the ride height significantly; document your starting position carefully.
24 mm
The stiffest option in this range, intended for highly developed suspension setups where maximum front spring control is required.
Ideal for:
• Dedicated track cars
• Motorsport applications
• Lightweight competition builds
• Cars with suitably matched rear spring rates and dampers

Information
High-performance Sway-A-Way hollow rear torsion bar set for Porsche 911 models equipped with the G50 transmission from 1987 to 1989. Available in 27 mm, 28 mm and 29 mm rates. Designed as a direct performance replacement for the original rear torsion bars, these tubular bars provide increased rear suspension control while reducing weight compared with equivalent solid torsion bars.
SET OF 2, One pair is required per vehicle
Fits:
Porsche 911 1987-1989 3.2L G50
Porsche 911 1978-1989 3.3L Turbo (930)
Always confirm that your vehicle uses the G50 transmission and corresponding rear suspension configuration before ordering.
The tubular construction is engineered so that the hollow bar provides the same effective spring rate as the equivalent solid-diameter torsion bar, while reducing the amount of material and therefore overall component weight.
Sway-A-Way torsion bars are manufactured from high-strength, heat-treated alloy steel. The bars are precision centreless ground for consistent dimensions and spring characteristics, then finished with a protective powder coating to help resist corrosion.
Available Torsion Bar Rates
27 mm - Fast-road and occasional track use
The 27 mm tubular rear torsion bar provides a useful performance increase while remaining a sensible option for cars that see regular road use. Sway-A-Way identifies the tubular 27 mm bar as having the stiffness of an equivalent solid 27 mm torsion bar while providing a useful weight reduction.
Recommended for:
• Fast-road Porsche 911s
• Uprated road suspension
• Occasional track-day us
• Cars using uprated dampers and front torsion bars
The 27 mm option provides greater rear suspension support without immediately moving to one of the highest rates in the range.
Technical Setup & Performance Notes:
• Unsprung Weight Benefits: Because the tubular bar is lighter, the suspension has less inertia. This allows your dampers to work more efficiently, resulting in better mechanical grip on rougher track surfaces or uneven canyon roads.
• Matched Balancing: A 27mm rear rate is a significant jump. To maintain the 911’s famous handling balance, it is highly recommended to pair these with 21mm or 22mm front torsion bars.
• Damping Requirements: Standard shocks may struggle with the increased "snap" of a 27mm rate. Custom-valved Bilstein or Koni dampers are recommended to properly control the rebound.
• Spline Care: During installation, apply a generous amount of waterproof anti-seize grease to the splines. Because tubular bars are more resonant than solid ones, proper lubrication is essential to prevent "creaking" or "clunking" sounds.
28 mm - Fast-road / track-day performance (not recommended for off-road use)
The 28 mm tubular rear torsion bar provides a further increase in spring rate, offering stronger control of rear suspension movement during hard acceleration and cornering.
Recommended for:
• Aggressive fast-road use
• Road and track-day cars
• Autocross
• Performance builds using modern high-grip tyres
• Cars with matched performance dampers.
This is a strong middle option for drivers wanting a more focused chassis while retaining some flexibility for road use.
29 mm Track-focused and competition-oriented applications (not recommended for off-road use)
The 29 mm tubular rear torsion bar is the firmest of these three G50 options and is aimed at more serious performance-oriented suspension setups.
Recommended for:
• Track-focused Porsche 911s
• Competition-inspired builds
• Autocross
• Lightweight cars
• High-grip tyre setups
• Cars with appropriately matched front torsion bars and performance dampers
The increased rear spring rate provides greater resistance to squat and roll but should be combined with a balanced overall suspension package.
Why Upgrade the Rear Torsion Bars?
The classic Porsche 911 suspension uses torsion bars as its primary springs. As suspension load increases, the torsion bar twists along its length. The resistance to this twisting action determines the effective spring rate.
Increasing the torsion-bar rate can provide:
• Reduced body roll
• Reduced rear-end squat during acceleration
• Improved suspension control
• More immediate chassis response
• Greater stability during fast cornering
• Better support for high-grip modern tyres
• Improved control during track use
• Improved balance when combined with complementary front suspension upgrades.
The larger the effective torsion-bar diameter, the greater the spring rate.
Tubular / Hollow Construction
Sway-A-Way tubular torsion bars are designed to reduce weight without sacrificing the desired spring rate.
The internal diameter of the hollow bar is engineered so that its torsional stiffness corresponds to the stated solid-bar rate.
This means a 27 mm tubular-rate bar is designed to provide the spring characteristics associated with a 27 mm solid torsion bar, rather than simply being a hollow 27 mm tube with a significantly softer rate.
This construction provides an attractive combination of:
• High torsional strength
• Reduced component weight
• Consistent spring rate
• Durable performance
• Motorsport-oriented engineering.
For Porsche owners looking to reduce unnecessary weight while upgrading suspension performance, the tubular design provides a useful advantage over conventional solid bars.
