Whilst we ensure that our parts are made to the highest standards, as the fitment and use are outside our control, and as use for racing is likely to ultimately result in failure, we can accept no liability whatsoever for damage resulting from such a failure. This is a condition of our business, which you are deemed to have accepted upon purchasing parts from us. However, if on receipt of goods purchased from Trident Engineering, you are not totally satisfied with the quality of workmanship or material, we will be happy to supply replacements or refund any monies paid. Electrical goods are non returnable after 14 days.
