Moser Engineering offers The ultimate Autocross Housing and Brake option packages for those who want to take their street car to the top level of performance and competition. One of the hottest trends in the street market is the Ultimate Street Car Challenges type events held at many car shows or Goodguys type shows. These competitions can be on a drag strip, an air field, road course or even a very tight obstacle course in a parking lot. These also tend to be some of the most enjoyable and also some of the most abusive events for a car owner. This package is built to handle all of these events without compromise. When it comes to making your street car or street rod perform at the top of its ability then you need the Moser Autocross package. This kit gives you the ability to deliver the power reliably to the ground. It also allows you to get the best performance from your brakes without brake kickback common from a flanged axle when used in extreme and very aggressive handling car packages. This kit is an adaptation of a full on Pro Auto Cross style rear-end and can be fitted to work with stock suspension or most aftermarket setups. This is available as an upgrade option for any of the Moser packages. This would include any of the housing and axle packages, complete rear end assemblies along with the Muscle Pak line of rear ends.

*Frame rail interference is prevelant when using the Emergency Brake Caliper & Cable set up on the GM "A-Body" & "G-Body" type vehicles!
