hey new to this forum, ive done a quick search, but just wanting to know how many rpm
my 4.2 gu coil cab should be doing with factor 4.1 ratios and 35s when the speedo shows 100kph.

currently it does around 2150-2200rpm, is this roughly what others get with standard ratios

im planning on changing to 4.3s or 4.6s. i tow a 6x4 work trailer every day, weekends im up bush. what r ur thoughts??
