How to Use Competition Engineering Materials

Building race vehicles is one of the most popular sports and recreation activity in the United States. Fans, participants and judges of automotive sporting events have brought the largest recognition and revenues to companies that sponsor and create events for race fans to attend. The materials and parts that make up a high quality race vehicle must be used in conjunction with a proper design in order to deliver the results that are needed to be a part of many sanctioned race events. Moroso's Competition Engineering produces high quality body and suspension parts that can be used to build a stock vehicle or custom design into a high speed winning machine. Getting started is as easy as finding the next project to add better driving and control using Competition Engineering materials and parts.

Things You'll Need

• Competition Engineering rear axel housing
• Competition Engineering (three-way adjustable drag shocks)
• Hydraulic jack
• Four jack stands or 4" x 4" wooden blocks
• ½ inch torque wrench (adjustable)
• ½ inch drive socket wrench (7/8, 1 ½ an 11/16 sockets)

Instructions

1. Lift the vehicle off the ground and support using lift jacks or wooden blocks at least 18 inches off the floor. Use the hydraulic jack to raise and lower the vehicle, then support the weight on secure footing during the installation of Competition Engineering materials, such as rear end axel housings and adjustable shocks.

2. Secure the Competition Engineering rear end axel housing to four-link suspension bars by adjusting the suspension bars to fit into the housing brackets correctly and at the same height as the transmission drive shaft yoke when resting on its own wheels and tires. Using the adjustable suspension bars to locate the center of the gear axel yoke to the transmission yoke will allow for the installation of a Competition Engineering drive shaft in between the transmission yoke and the rear gear yoke for transfer of power to the wheels. Tighten the nuts of the four-link suspension and axel housing to 120 ft lbs. of pressure using a torque wrench set at 120 ft lbs.

3. Use a spanner wrench to adjust the Competition Engineering drag race shocks to the correct position prior to installing. Competition Engineering materials like their three-way adjustable drag shocks show how improved the equipment has become over stock shock absorbers. Install the shocks using the top and bottom brackets of the four-link suspension system. Two rear shocks are secured using a wooden dowel to align the holes in the suspension brackets to the shock absorber arm eyelets. Secure using a nut and bolt system and tighten to 120 ft lbs. of pressure. Be sure to check that the coil over springs do not deflect any of the pressure put onto the shock when the vehicle is resting on its own weight. Use a spanner wrench to adjust the space that holds the coil over springs into the top and bottom support of the shock absorber body.

4. Remove the supporting jacks or wooden blocks from under the vehicles so that after the addition of the Competition Engineering materials, you can test and tune the equipment. By adding the ability to adjust how their equipment and materials work, Competition Engineering gives the end user as much customization as needed by the rest of the vehicle design. Producing high quality parts is easy, but installation and tuning take time.

5. Measure the distance between the ground and the vehicle frame. Be sure that the rear end axel was installed correctly and that the four-link suspension bars are properly aligned. Check the drive shaft connection between the transmission and the rear axel housing. Is it level, or at an angle that is within its operational tolerance? While many rear end and transmissions ride at different heights, and extreme angle of entry for a drive shaft from transmission to rear axle is not recommended. Adjust the suspension bars to raise or lower the height of the rear end housing to get a better pathway for the drive shaft to connect to.

Tips & Warnings

• Competition Engineering parts are great for dragsters and door slammers who race professionally or semi-pro. Moroso parts can complement any Competition Engineering project that requires engine modifications of high quality.

• Be sure that when supporting a vehicle above the ground that you do not work under a vehicle that is lifted off the ground only by a hydraulic or mechanical jack. Only vehicles that are supported by solid materials and rated jack stands are safe to work under for long periods of time.
