Upgrading from the stock axles becomes an issue when you start to play hard. If you
really want to go out and run with the big guys, or compete, 1/2 ton axles aren't going to
last long. So 1 ton drive train is the way to go, what if you already have 1 ton
axles and they are not enough, or you want an ultra strong rear steer set up?
Well,
you could get Rockwells or Mog axles, but the cost of the axles them selves, custom
wheels, a revamped suspension to accept your new hard ware, adds up, not to mention the
weight of those monsters.
Sunray Engineering has come up with a great
solution. It combines the proven strength of the Ford 9" center section, with
an all new custom outer assembly that is rated to take 1100 more foot pounds of abuse than
even the revered Dana 60.
The new 1550 is built with your current set up in mind, as
well as strength. It can be fitted with all of the mounting brackets for popular
applications and will use bolt patterns from 5 on 5.5 up. |

We start with the knuckles, the inner is made of 1" bent steel plate. This
particular housing is for a custom rear steer application. |

The outer knuckle and spindle seen here with
the hub, u-joint, yokes, and shafts. The double splined inner and outer shafts are
made from 4340 alloy. Notice also the tapered bearing is replacing the king pin or
ball joints, for ease of steering, longevity, and strength. |
 |
Here you see the 1550 yoke and U-Joint up against the
Dana 60. The yoke and U-Bolt design are stronger than conventional axle shafts, one
because of their sheer size, and two because the U-Bolt keeps the cup from turning in side
its self, which causes deflection and ultimately failure. |
 |
Once assembled it is easy to see how massive the
assembly is, however it still fits in a 15" wheel. Notice the large caliper and
rotor, and the high steer option. |

Ready for final paint and install. |
