When fitting please consider replacing any wear parts at the same time. Items such as top mounts, mounting cups and other suspension bushes are likely to be worn. We strongly advise to have the vehicles tracking checked and adjusted after fitting as any suspension changes will likely cause incorrect alignment. This can result in excessive and uneven tyre wear and affect vehicle handling. 

"Warning. 
Please thoroughly clean and lightly lubricate the threads of the shock & adjusting collar prior to turning the collar. 
This will avoid galling any dirty threads."
