Do I need one kit or two?
Each kit is one pair: 2 spacers plus the hardware for one axle (two wheels). To do all four wheels, order 2 kits. Front and rear can be different thicknesses.
Which thickness should I pick?

What does hub-centric mean?
The spacer's center bore matches your factory hub, and the lip on the spacer matches the bore in your wheel. The result is a vibration-free fit.
What will not fit?
Cars with center lock wheels. They have no bolt pattern, so no spacer fits them.
What is the warranty?
Every 4WheelSpacers product is backed by a lifetime warranty.
