Swivels are available at a std 3deg on an exchange (please check availability if you need this service) basis which will cover you for up to 2.5 - 3" of lift
We can also custom machine swivels as per you current caster measurement, or wheel alignment report and machine them to suit how much you're out.
Correction at the swivels does NOT rotate the whole axle housing - the swivels are the only thing to rotate.
