TGK Rear Spherical Strut Perch For Audi

The TGK Motorsport Billet Rear Spherical Strut Perch replaces the factory rubber strut mount with a precision spherical bearing assembly, removing unwanted deflection while allowing the strut to articulate smoothly through its full range of motion. This rigid, billet housing paired with a PTFE-lined spherical bearing eliminates the compliance that directly affects rear suspension behavior during cornering, braking, and rapid load transitions.

The factory rear strut mount uses a rubber isolator that allows the strut to move under load, compressing and deforming when load is applied and causing the strut to shift relative to the chassis. This movement changes suspension geometry moment-to-moment, making the rear of the car less predictable and harder to control at the limit, especially on vehicles with stiffer springs, coilovers, wider tires, or increased grip.

Specifications

Part Number: TGK-0411-08
Material: CNC-Machined 6061-T6 Aluminum
Bearing Type: PTFE-Lined Spherical Bearing
Application: Rear Strut / Coilover Systems
Use Case: Performance Street & Track

Features

Eliminates Rear Suspension Deflection: Removes rubber isolator compliance for immediate, repeatable suspension response during transitions and mid-corner loading.

Billet 6061-T6 Aluminum Construction: CNC-machined from solid aluminum for strength, dimensional stability, and prevention of deformation under load.

PTFE-Lined Spherical Bearing: Self-lubricating bearing allows smooth, unrestricted strut movement without binding or maintenance requirements.

Maintains Alignment Under Load: Holds strut in fixed position relative to chassis, keeping camber and toe consistent when suspension is loaded.

Improved Stability and Chassis Balance: Fixed rear suspension geometry creates more predictable reactions to throttle, braking, and steering input.

High-Load Durability: Spherical bearing designed for sustained mechanical load and aggressive use without deterioration from heat or load cycles.

⚠ Spherical Suspension Parts ⚠ 

Vehicles equipped with spherical bearings, heims, uniballs, solid bushings, or other performance suspension components may experience increased noise, vibration, and harshness (NVH) compared to factory OEM components. Occasional squeaking, creaking, clicking, or other operational noises are considered normal characteristics of these performance-oriented parts and do not necessarily indicate a defect or failure.

Noise levels can vary based on installation, driving conditions, weather, maintenance, and normal wear. Regular inspection and maintenance are recommended to ensure proper performance and longevity. By purchasing and/or installing these components, the customer acknowledges and accepts these characteristics as part of a high-performance suspension system.

Due to the Nature of Spherical Suspension Parts, there is a One Year Limited Warranty from Purchase Date.
