My Custom Drivesahft Safety Loop Since I couldn't use my Lakewood DSL with my new Midwest Chassis 9" w/ the long TQ arm, I decided to fab up my own, went to a steel yard and picked up 2 2x1/4" 12" long steel plating and a 2" wide 5" inside dia. steel pipe. After some welding and some torching and bending, this is what I came up with.....fits real nice too.

Nice job, it looks factory made.
If that shaft broke right behind the loop, would the rear piece of the remaining shaft drop and still be able to hit the ground?
Seems as if the loop should be further back, to a point where there isn;t enough length if a breakage occured that it will touch the ground.
Maybe I just can't see that in the pics.

Yeah, my stepfather is making mine. We measured the distance with the DS hanging down towards the ground while on a lift, then backed that spot up 3 more inches, thats where DS loops need to be. A breakage anywhere forward of that and it'll just drag along or be held up by the loop even if the breakage is just a few inches from the tranny.
Might even do a forward loop that will assure that no part of the DS can touch the ground no matter where it breaks.

The NHRA rules require a driveshaft loop within 6" of the front U-joint when your car is capable of 13.99 quarter mile times with slicks or 13.00 with street tires.
Granted I'm more like 8-9" from the front u-joint......plus two things you have to think about here....most driveshafts will break on the launch which means for the most part the back part will stop spinning right there where as the front part will continue to spin becuase you are still in gear, this is where the DSL plays another role here and that is not letting the driveshaft spin out of the area of the DSL, which if wasn't there would most likely break your tailhousing off and spit trans fluid all over the track.

Hell, make another one for up rear, that one turned out real nice.

Thats true, but I'd be more concerned with ME and my car, I could care less about fluid on a track. If the DS breaks 2-3 seconds after launch or when hitting 3rd gear, in the right place you could flip the car. Thats why, really, 2 loops are needed if you want to satisfy the track rules and save your life. Track rules are flawed for not requiring 2 loops. Saving of the life is priority for me. I think I'm gonna go with 2 loops but if I go with just one it'll definitely be within 7 inches of the rear-end u-joint. 100% safe in all breakage situations. I do roll runs from 50-180, so I need the loop to keep my car from getting launched end-over-end if it breaks.
