So you’ve broken into a new ET zone and gone quicker than you expected — the problem is that you don’t have the roll bar required for this, and the track officials aren’t pleased. The solution to this dilemma is to add the NHRA required jungle gym to your ride, but that can make getting in and out of the car a chore for street use. To make getting in and out easier you can add a swing-out bar to the roll bar that uses a clevis set from Chis Alston’s Chassisworks.
Depending on the type of car you bring to the track, putting a roll bar in can make things really tight inside in a hurry, so having the added accessibility of a swing-out door bar is a great option. Chris Alston’s Chassisworks pioneered the use of a clevis set for a swing-out in a door car and has helped make this a viable option for racers who want to go fast, remain safe, and have a higher level of access to their car with a roll bar in it.
The billet steel clevis sets are available in tube sizes that give chassis builders options and include 1-5/80-inch by .134-inch, 1-5/8-inch by .083-inch, and 1-3/4-inch by .134-inch. The radial slot and chamfered flats on the clevis sets lower the stress concentration on the set where the pin secures the bar. The use of a counterbore reduces the weight of the system and provides a heatsink effect for quality welds during installation. Chris Alston’s Chassisworks also offers their Gemini Tube Connector that allows for the removable attachment of 1-5/8-inch by .083-inch tubing to a flat surface like a framerail or firewall.
You can learn more about the clevis sets right here and here on the Chris Alston’s Chassiworks website.
