Astra H Pillow ball top mounts

RnD Motorsport Pillow Ball Top Mounts

Astra H

These Top Mounts replace the large rubber mounting that is on top of your front struts. Instead of being rubber, they are solid aluminium bearing housings that encase a high precision, maintenance free, spherical bearing. On the VXR range of cars there is the aditional benefit from removing the singular use plastic strut retaining clips that secusre the standard strut in place, these come with lockrings that hold the strut top tight to the chassis. 

This allows the wheel to retain it's set geometry whilst enduring any loads, such as cornering, braking, or during acceleration. During cornering it stops the front wheel "flopping" over into positive camber and reducing its contact area with the road. You can run less static front camber with these fitted than you had to with the originals to keep the tyre temperatures uniform, due to the lack of movement.

Working in the very limited space of the standard strut tower, they are designed to push up inside the strut tower, like the originals, and then clamp in place via a locking ring. The locking ring also features locking screws to physically prevent it from unwinding or coming loose in harsh conditions.

We have developed them to fit the standard damper / strut top. Any aftermarket dampers that use the original rubber strut top and bearing assembly should work with these, we have had them fitted to Gaz, Bilstien and KW coilovers for example. This advert shows them pictured with the Bilstien B14 front struts (Without adjuster in the top)  and the KW v2 front strut (adjuster in the top )

If you find that they do not fit your specific set up, we would love to help you make them do so. They are fairly universal, so usually it would just mean some different spacers. Getting them to fit will allow us to expand our list of known fitments, so we don't mind at all. We will fully refund you if we cannot make them fit any damper that uses the original top mount, provided you send them back undamaged.

These pillow ball top mounts come as a pair, including new custom CNC machined stainess steel strut top securing nuts .  These nuts are threaded all the way through so dont be alarmed if your damper shaft does not come all the way through the securing nut.

Note; These come with hardware to suit the standard fitment M14x1.5 thread on top of the dampers, any other thread will need custom nuts, contact us to arrange this as we can usually make them fit most shocks.

Designed for competition use, professional installation recommended, must be lubricated with PTFE spray every now and again and immediately if any creaking is heard from them.
