Replacement For Item No 21
Control arms are critical suspension links that locate the wheel assembly relative to the chassis while allowing controlled suspension movement. Their geometry directly influences wheel alignment and therefore affects tyre contact, steering response, stability and handling.
The adjustable design is particularly valuable on competition, track-prepared or modified vehicles where suspension geometry may need to be optimised following changes to ride height, wheel and tyre specifications or other chassis settings. Adjustment can allow a specialist to achieve alignment settings that may not be possible with a standard fixed arm.
What This Product Does:
Symptoms Of Wear Or Failure:
- Knocking, clunking or rattling from the suspension.
- Excessive play in the control arm joints or mounting points.
- Loose or worn spherical joints, bushes or associated components.
- Steering that feels vague or inconsistent.
- Reduced stability during braking or cornering.
- Vehicle pulling or wandering on the road.
- Difficulty maintaining the required wheel alignment.
- Uneven or accelerated tyre wear.
- Changes in handling or steering response.
- Visible bending, cracking or physical damage.
- Corrosion or deterioration affecting the component.
- Adjustment hardware that is damaged or can no longer be securely set.
- Suspension geometry moving out of specification after adjustment.
- Damage discovered following heavy track use or an impact.
Why Replacement Matters:
- Control arms are structural suspension components that directly influence wheel position and alignment. Excessive wear, damage or movement can allow suspension geometry to change while the vehicle is being driven, negatively affecting steering precision, tyre contact and vehicle stability.
- This becomes especially important in motorsport and high-performance applications. Higher cornering forces, aggressive braking, track kerbs and performance tyres can place substantial loads on suspension components. Any unwanted movement within the control arm or its joints can compromise an otherwise carefully configured chassis setup.
- Incorrect suspension geometry can also cause rapid or uneven tyre wear. On a performance vehicle, relatively small alignment changes may noticeably alter steering response, cornering balance and tyre behaviour.
- Adjustable control arms additionally depend on their adjustment and locking mechanisms remaining secure. Damaged, incorrectly adjusted or inadequately secured hardware can allow the geometry to move away from its intended setting.

Information
Fork control arm, FRONT.
Front lower control arm (also referred to as "track bar" or “front lower link”) designed to replace the original factory arm on a variety of modern Porsche models including 991-series 911, 981/718 Boxster and Cayman. The control arm is supplied as a single unit, ready for direct installation using the original mounting hardware (or new bolts, if required). To ensure balanced suspension performance, we recommend replacing both the left and right control arms at the same time.
Sold each, 2 required per vehicle.

• Position: Front axle — lower control arm / track bar (left or right side).
• Role in Suspension: Controls wheel alignment (camber, toe), locates the front wheel assembly under dynamic loads, absorbs road forces, and helps maintain stable handling during braking, acceleration and cornering.
• The front control arm maintains precise positioning of the wheel relative to the chassis, ensuring correct suspension geometry under load. Its bushings isolate road vibrations while allowing controlled suspension movement, preserving both ride comfort and steering accuracy. As a direct-fit replacement, it restores proper front suspension behaviour without the need for modifications.
With age and mileage, the bushings and ball-joint in the control arm gradually wear due to road stress, heat, and repeated load cycles. This can lead to vague steering, poor straight-line stability, uneven tyre wear, knocking noises, or difficulty holding correct alignment. Replacing the arm ensures tight, predictable suspension response and safer, more controlled driving dynamics - especially important for high-performance vehicles or those driven hard.
When to replace:
• Noticeable knocking or clunking from front suspension over bumps or braking
• Loose or vague steering feel, especially at speed
• Uneven or premature tyre wear on front tyres
• Difficulty achieving or maintaining correct wheel alignment (camber/toe)
• Excessive play discovered in control arm joint on inspection
• Completing other suspension work (bushings, shocks, struts) - good practice to renew suspension links together

The lock nut fastens the control arm to the wheel carrier, helping keep the suspension arm securely mounted in its correct position. This connection is important for maintaining suspension geometry, wheel alignment, and stable handling. Depending on the model, it may be used on front or rear suspension arm connections where Porsche specifies an M12 x 1.5 locking nut.
Functions
• Secures the control arm to the wheel carrier
• Helps maintain correct suspension alignment and geometry
• Supports stable wheel location during driving, braking, and cornering
• Helps prevent loosening caused by road vibration and suspension movement
• Provides a secure OE Match replacement for the original lock nut
• Suitable for suspension repair, control arm replacement, or wheel carrier service
Suspension lock nuts are safety-critical fasteners and may lose locking strength after removal. They can also become corroded, damaged, rounded, or worn over time. Replacing the lock nut during suspension work helps ensure the control arm is secured correctly and reduces the risk of loosening after reassembly.
When to replace
• This Part The control arm has been removed or replaced
• The wheel carrier or suspension arm connection has been dismantled
• The original nut is corroded, damaged, rounded, or seized
• The nut no longer tightens or locks correctly
• Suspension repairs or alignment-related work are being carried out
• There is play, looseness, or noise from the control arm mounting area
• As recommended during service where single-use locking hardware is removed
