Side Gearbox/Engine Mount Fitting – Astra G/H and Zafira A/B

Astra G/H 2.0 Petrol Turbo, Astra H 1.9 CDTi, Zafira A/B 2.0 Petrol Turbo and Zafira B 1.9 CDTi have a gearbox side mount that is rubber and prone to failure.

Courtenay Sport approached Powerflex to devise a solution to not only improve the original factory mount, but also give it some additional support and to help reinforce it. In some cases where the original factory mount is not too badly damaged or split, the polyurethane insert can be used to ‘save’ the failing factory mount and prevent further deterioration.

Two specifications of material are available for this mount: Yellow for road use (Shore Hardness 70) and Black (Shore Hardness 95) more aimed at trackday/competition use as it is much stiffer.

We recently fitted a yellow mount insert to an Astra H VXR which had covered just over 46,000 miles and the factory mount was already showing signs of weakening due to splitting which if left would ultimately deteriorate fully and  fail completely.

Once fitted there was no noticeable increase in NVH (Noise, Vibration, Harshness) into the vehicle. The vehicle used also had an uprated front engine mount insert fitted. Additionally it was noted that the gearchange had improved and became smoother due to the reduction in gearbox movement at gearchange, due to the uprated gearbox mount insert.

On vehicles with a full set of uprated engine mounts, some minor change in NVH may be experienced by fitting this additional mount.
