An axle housing (110) for clamping with a clamp assembly (118, 218) to a spring (16, 216) of a suspension system (14) of a vehicle, the clamp assembly having at least two U-bolts (120, 220) each having a curved portion (136, 236) and two generally linear legs (128, 228) extending therefrom, and a clamping plate (122, 222) for receiving and attaching the legs of the U-bolts to form an enclosure that clamps the axle housing (110) to the spring (16, 216), the housing having a generally oval shape in cross section. The axle housing (110) has a generally planar fore side (132), a generally planar aft side (134), a generally rounded top surface (144) and a generally rounded bottom surface (146), wherein at least one of the top surface and the bottom surface are sized and arranged to mate flushly with the curved portion (136) of the U-bolts (120).
