Hi all. I want to install elockers front n back, at same to update diff gears for 33" tyres. Current ratio is 3.07. Looking for advice of best source and to have them installed.. im in caringbah, happy to travel across the city.

Think best ratio would be 4.11. Plus to upgrade the speedo gear to align to diff ratio n tyre size. I have a 2004 manual tj. Thanks.
