What Does the Auxiliary Support Cross Tube Do?

The auxiliary support cross tube is mounted across the front underside of the vehicle and forms an important structural part of the suspension system.

Its functions include:

• Supporting front suspension components
• Providing secure suspension mounting points
• Helping maintain correct suspension geometry
• Maintaining structural rigidity across the front suspension
• Supporting accurate steering and suspension operation

Because suspension loads are transferred through this area, the condition and alignment of the cross tube are important for correct handling.

Why Do Auxiliary Support Cross Tubes Fail?

Unlike a normal service component, the cross tube does not have a scheduled replacement interval. Damage is generally caused by age, corrosion, accident damage or previous repairs.

Common problems include:

• Corrosion and rust
• Damage around mounting points
• Distortion caused by accident impact
• Cracks or metal fatigue
• Damage from incorrect jacking or lifting
• Worn or enlarged mounting holes
• Previous poor-quality repairs
• General deterioration on older vehicles

Corrosion is particularly important on early Porsche 911 models, where decades of exposure to moisture and road contamination can weaken suspension mounting areas.

When Should the Cross Tube Be Replaced?

Replacement should be considered if:

• Significant corrosion is present
• Suspension mounting points are damaged
• The cross tube is bent or distorted
• Cracks or structural damage are found
• Suspension geometry cannot be correctly adjusted
• Accident damage has affected the front suspension
• Previous repairs have compromised its strength
• The component is unsuitable for reuse during restoration

Any suspected structural damage should be carefully inspected before the vehicle is returned to the road.

Important Front Suspension Checks

When replacing the auxiliary support cross tube, the surrounding suspension and mounting areas should also be inspected.

Check the spring struts, suspension arms, bushes, ball joints, steering components, mounting hardware and body attachment points for wear, corrosion or damage.

A wheel alignment should be carried out where necessary after suspension components have been replaced or disturbed.

Porsche 911 1969-71 Front Suspension Cross Tubes

Early Porsche 911 suspension components are now several decades old, making corrosion, previous accident damage and general deterioration increasingly common.

The auxiliary support cross tube is an important part of the front suspension structure. Damage or corrosion can affect suspension mounting, alignment and overall front suspension integrity.

During restoration of a 1969, 1970 or 1971 Porsche 911, the cross tube and surrounding suspension mounting areas should be carefully inspected, particularly where corrosion or previous repairs are visible.

Auxiliary Support Cross Tube.

The OE Match Auxiliary Support Cross Tube is a replacement structural component for the front suspension of early Porsche 911 models. Mounted across the front underside of the vehicle, the cross tube forms an important part of the suspension support structure, helping locate and securely support associated suspension components.

Fits:

• Porsche 911 2.0L 01/63-07/68

Diagram Ref No 1

A sound cross tube is essential for maintaining the correct position of suspension mounting points and preserving accurate front suspension geometry. This directly contributes to predictable steering, wheel alignment, handling and overall chassis stability.

The OE Match replacement is suitable for restoring an early Porsche where the original cross tube has become corroded, damaged, distorted or otherwise unsuitable for continued use.

What This Product Does:

• Forms part of the structural support for the front suspension.
• Provides secure mounting and location for associated suspension components.
• Helps maintain correct front suspension geometry.
• Supports accurate wheel alignment.
• Adds structural rigidity across the front suspension assembly.
• Helps maintain stable and predictable steering behaviour.
• Transfers suspension and road loads through the mounting structure.
• Replaces an original cross tube that has suffered corrosion, accident damage or distortion.
• Provides an important structural foundation during restoration of an early Porsche 911.

Because suspension geometry depends on accurately located mounting points, the condition and shape of the cross tube are important to the way the car steers, brakes and responds to changes in road surface.

Symptoms Of Wear Or Failure:
Unlike a rubber bush or ball joint, the cross tube does not normally wear through regular movement. Problems are more commonly caused by corrosion, impact damage, fatigue or previous poor-quality repairs.

Signs that the cross tube may need attention include:

• Visible corrosion or heavy rust.
• Rust perforation or significant metal loss.
• Cracks around mounting points or stressed areas.
• Bent, twisted or distorted sections.
• Damage caused by an accident or underbody impact.
• Suspension mounting points no longer correctly positioned.
• Difficulty achieving correct wheel alignment.
• Vehicle pulling or wandering despite alignment adjustment.
• Uneven tyre wear associated with incorrect suspension geometry.
• Inconsistent steering response.
• Unusual suspension noises where mounting points have become damaged or weakened.
• Evidence of previous welding or poorly executed structural repairs.
• Excessive deterioration discovered during vehicle restoration or inspection.

On classic Porsche 911 models, age-related corrosion and previous accident damage are particularly important considerations because these vehicles are now several decades old.

Why Replacement Matters:
The auxiliary support cross tube is more than a simple bracket. It forms part of the structure that determines where key front suspension components are positioned.

If the cross tube becomes badly corroded, bent or damaged, the suspension mounting points may no longer remain in their intended positions. This can alter suspension geometry and make accurate wheel alignment difficult or impossible.

A compromised cross tube may contribute to:

• Poor wheel alignment.
• Uneven tyre wear.
• Reduced steering precision.
• Vehicle wandering or pulling.
• Unpredictable handling.
• Incorrect suspension component positioning.
• Increased stress on surrounding suspension and chassis components.
• Reduced structural integrity of the front suspension assembly.

Replacing a damaged cross tube restores a sound structural mounting point and allows the suspension to be correctly positioned and aligned again. This is particularly important during restoration, accident repair or comprehensive suspension refurbishment.

The product you are viewing cross references to these numbers

The 911 341 013 10 is an aluminium front cross-member, also known as an auxiliary support. Its primary function is to carry suspension loads and maintain proper alignment of the front control arms, steering rack, and related substructures.

On vehicles originally equipped with a steel cross-member, converting to this aluminium version requires two additional mounting brackets (part number 911 341 031 01) for proper installation. In essence, this part is a structural component of the front end that directly supports suspension geometry and ensures stable alignment.

Fits:

• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC

Technical / Material Considerations & Properties

Weight savings: Aluminium is significantly lighter than steel. The use of aluminium here reduces the sprung mass (mass carried by the suspension) which can improve responsiveness in handling. Mounting hardware & bushings: 

The aluminium cross-member is only as good as its mounting points, brackets, and isolating bushings. Bolts, washers, cups, and bushes must be properly specified (torques, pre-load, orientation) to avoid introducing stress concentrations or deforming the part.

Fits To Diagram Ref No 14

The bushings provide the flexible mounting points between the front control arms and the vehicle chassis. Their rubber construction allows the suspension arms to move through their normal operating range while absorbing vibration and controlling unwanted fore-and-aft or lateral movement.

Unlike harder polyurethane, solid or competition-style bushings, these standard rubber bushings are intended to retain a factory-style balance of ride comfort, noise isolation and suspension compliance.

They are particularly suitable for road cars, restorations and vehicles where maintaining original Porsche suspension characteristics is preferred.

What This Product Does:
The front control arms locate the front wheels and help maintain the suspension geometry as the wheels move over bumps, during cornering and under braking.

The control arm bushings sit between the arms and their chassis mounting points.

Their functions include:

• Supporting the front lower control arms
• Allowing controlled suspension movement
• Absorbing road shock and vibration
• Reducing noise and harshness transmitted into the chassis
• Controlling unwanted movement of the A-arms
• Helping maintain stable wheel alignment
• Supporting predictable steering response
• Maintaining front suspension geometry under braking and cornering
• Providing a compliant pivot point for suspension movement

Healthy bushings allow the control arms to move in the intended direction while resisting movement that could disturb wheel alignment.

Symptoms Of Wear Or Failure:
Common symptoms of worn front control arm bushings include:

• Clunking or knocking from the front suspension
• Noise when driving over bumps
• Knocking during braking or acceleration
• Vague or imprecise steering
• Vehicle wandering on the road
• Reduced straight-line stability
• Steering requiring frequent correction
• Front-end movement under braking
• Steering-wheel vibration or shimmy
• Uneven front tyre wear
• Changes in wheel alignment
• Reduced steering precision
• Front suspension feeling loose
• Visible cracking in the rubber
• Rubber separating from its mounting surface
• Bushings becoming hard or distorted
• Control arm visibly moving excessively within its mount

Because several suspension components can create similar symptoms, the complete front suspension should be inspected before replacement.

Why Replacement Matters:
Worn control arm bushings allow the suspension arms to move more than intended.

This can alter wheel position dynamically as the vehicle is driven.

Excessive control-arm movement may contribute to:

• Unstable steering
• Poor wheel alignment
• Uneven tyre wear
• Reduced braking stability
• Less predictable handling
• Increased suspension noise
• Additional stress on surrounding suspension components

Replacing deteriorated bushings restores controlled suspension-arm movement and helps return the vehicle to its intended steering and handling characteristics.
