- Spacer bushings between the mounting bolt and the front shock absorber, top, Royal Alloy, for GP, GT, JPS, TG
Genuine Royal Alloy rosette-shaped spacer bush for the upper mounting of the front shock absorber. The component is installed between the head of the mounting bolt and the upper shock absorber mount. It serves as a defined spacer and provides a suitable contact surface for the bolted connection.
The spacer bush is part of the standard shock absorber mounting system used on Royal Alloy GP, GT, JPS and TG models. It is listed as a separate component in the Royal Alloy spare parts catalogue under original part number 0307070013-02-001.
The front shock absorber is secured to its upper mounting point by a bolted connection. The specially shaped spacer bush is positioned between the bolt head and the shock absorber mount.
Unlike a simple flat washer, the rosette has a pronounced three-dimensional profile. Its shape is designed for the intended installation position and provides a defined contact surface for the mounting bolt.
The spacer bush performs two essential functions: it maintains the specified distance between the components involved and provides a metallic contact surface for transferring the clamping force of the bolt.
As part of the upper shock absorber mounting, it helps ensure that the connection can be assembled in accordance with the original design.
The spacer bush has a circular basic shape with a central through-hole. Its silver-coloured metallic surface shows clearly visible machining marks.
The outer profile is not completely flat. A broad annular contact surface transitions via an angled section into the raised inner area. This creates the characteristic, slightly dished profile of the rosette.
The central hole accommodates the mounting bolt. Concentric machining marks are visible on the annular surfaces, typical of the machining process used for rotationally symmetrical components.
The opposite side also features an annular contact surface. The combination of the central hole, stepped outer profile and defined contact surfaces distinguishes this spacer bush from a conventional flat washer.
The Royal Alloy spacer bush is designed as a vehicle-specific genuine replacement part. Its dimensions correspond to the intended upper shock absorber mounting.
The spacer bush is used on various Royal Alloy models as part of the upper mounting of the front shock absorber.
In the Royal Alloy spare parts catalogue, the component is listed as “Outer Bushes” with dimensions of 6 x 17 x 4 mm. Exact vehicle compatibility should be checked using original part number 0307070013-02-001.
When removing the front shock absorber, the spacer bush should be checked for damage and deformation. Particular attention should be paid to the central hole, the annular contact surfaces and the stepped outer profile.
A damaged or deformed rosette should be replaced so that the mounting can be reassembled with the intended component geometry.
Before assembly, the contact surfaces of the shock absorber mount and the mounting bolt should be inspected. The spacer bush must be installed in the intended orientation.
The mounting bolt must be tightened in accordance with the manufacturer's specifications. Ensure that all components belonging to the upper shock absorber mounting are correctly positioned.
The genuine Royal Alloy spacer bush with original part number 0307070013-02-001 enables the targeted replacement of an individual mounting component. This allows the upper shock absorber mounting to be reassembled according to the original production design during maintenance or repair work.
