A road trip boom triggered by international travel restrictions has underpinned record sales growth at auto parts manufacturer and retailer ARB Corp.

ARB shares jumped more than 6 per cent to a record high of $31.28 on Wednesday after the company said revenues in the September quarter rose 17.7 per cent - well ahead of market forecasts around 14 per cent, and more than double the rate of sales growth in the December half 2020.
