Hollow One-Piece Front Axle Shaft Offset 4 Duralumin for RDX YD-2 GRK You will receive only two of the duralumin hollow one-piece front axle shafts with an offset of 4, as shown in the photo. Weighing in at an incredibly light 1.6g, acceleration and deceleration will improve dramatically. The offset 4mm hub-integrated design allows for highly precise tire and wheel rolling, and allows you to adjust the scrub radius to your liking. 1.6g/pcs, offset 4mm standard. Please prepare shim spacers separately. Made by Metal Garage
