The Proline axle is under sized (flaw) and fits the bearings sloppy which translates into a sloppy front wheel. I have seen the AE one and it is a perfect fit and the steering block spreads the bearings out farther making for better wheel bearing support. Just a better product.
... Just my 2 cents though.
