Competition Drag racing Drive shaft loops ?

[Toolman9304]

I have an 04 QC 4X4 that I am planning to run in the DHRA quick diesel class.

Is there anyone out there that makes drive shaft loops or some one with some pictures of ones that they have built. My main concern is the front one , I drive the truck everyday and need something that will move with the suspension or have enough room for it to move.

I like them Ladder Bars that they have. Wonder how much they weigh? Anybody here tell me if they have em and how heavy are they?

TIA, RD

Thanks Billywj

I am thinking about somthing with a single loop for each shaft. You know us drag racers don't want anymore weight then we have to have.

get a 6" pipe and cut it 6" long (minimum) and drill and tap or drill and weld on some nuts--run bolts thru so they clamp onto the pumpkin--just like a Christmas tree stand... chris

Good idea , but what do you do for the front of the shaft? It's the front of the shaft I would be worried about (I don't like pole vaulting).

you're talking transmission end??? if so can't you do the same???(I have an auto, thus my question)--



or you can do like I did and add a crossmember--schedule 40 pipe--then I made a mount that came off the transmission crossmember(really the skid plate)--ran a pc of flat stock that bolted to the the new pipe crossmember and to the transmission skidplate--then I welded the 6" pipe to that along with a loop from Summit racing that's close to the carrier bearing---I also split my 6" pipe in two halves so that it was easier to remove and install(I did this on all my loops)---on the rear I welded a some tabs onto the pumpkin and a tab on the carrier bearing bracket--took a pc of 1. 5" pipe(could've been 1. 25") and 1" pipe and slid the 1" pipe inside the bigger pipe--drilled holes thru one end of the big pipe and thru the end of the smaller pipe--each pipe was about 4' long if I remember correctly(maybe longer)---the reason for the sleeving is so that it can compress and de-compress along with the movement of the axle---ok to this pipe I welded all my loops(6" pipe and Summit loops)---I did the same on the from except that I have a CONFER axle truss that I welded a bracket to hold the end of pipe and came off the transmission skidplate for the other--same sleeve method--been on for 3yrs ata least---heavy yes--but I'm a sled puller--make it out of aluminum if you want---good luck---chris
