• Function: This bolt features an eccentric cam design that enables fine adjustment of suspension geometry. It’s critical for setting camber and toe angles, ensuring your Porsche tracks straight and maintains optimal tire contact for cornering grip and stability.
• Why Replacement Matters: Over time, eccentric bolts can seize, corrode, or deform due to constant exposure to road conditions and torque load. When this happens, alignment accuracy suffers, and adjustment becomes difficult or impossible.
• When to replaces: During suspension servicing or alignment work, When replacing control arms or bushings, If the original bolt is frozen, bent, or corroded

Information
Control arm upper, Rear.
This OE Match rear upper control arm is a suspension component designed for Porsche 911 (993) models. It forms part of the multi-link rear suspension system and connects the rear wheel carrier (hub assembly) to the chassis side section, helping control wheel movement and maintain proper suspension geometry.
Sold individually, Fits left or right side - Two required per vehicle.
Fits:
Porsche 993 1994 - 1997
Diagram ref no 5 and 28.
The rear upper control arm, sometimes referred to as the rear upper forward suspension link, is a key component in the Porsche 993 multi-link rear suspension layout. It links the rear wheel carrier to the body structure and allows controlled suspension movement while keeping the wheel accurately positioned relative to the chassis.
The OE Match rear upper control arm is engineered to match factory specifications for geometry, mounting points and structural strength. It typically includes the integrated ball joint and mounting points necessary for direct installation.
This component is commonly replaced during suspension refurbishment when ball joints or bushings become worn.
Function
• Suspension Link: Connects the rear wheel carrier to the chassis
• Wheel Alignment Control: Maintains proper camber and wheel positioning
• Handling Stability: Supports balanced handling during acceleration and cornering
• Suspension Movement: Allows controlled articulation of the rear suspension
Rear suspension arms and their ball joints are constantly subjected to road impacts, braking forces and suspension movement. Over time these components can develop play or wear, leading to poor handling, suspension noise and uneven tyre wear. Replacing worn control arms helps restore correct suspension geometry and improves driving stability.
When to Replace. Consider replacing the rear upper control arm if you notice:
• Clunking or knocking noises from the rear suspension
• Excessive play in suspension joints
• Uneven rear tyre wear
• Difficulty maintaining proper wheel alignment
