Why are people using front d/s loops?

[Mustangfreak]

I've always known to put a rear loop on when using d/r's, but why are people using the fronts?

because 05-07's have a two piece drive shaft, so you need two loops, or replace the 2 piece with a 1 piece and get 1 loop.

I knew it has a 2 peice from Ford, but I've seen a few pics of front loops being used one 1 peice d/s's

Doesn't the loop goes towards the front of the DS? I think I read somewhere that NHRA requirement is the loop I think 6 or 8 inches from the front u-joint. It makes sense if the front fails it will prevent the DS from burying into the pavement and catapulting your car....

Zackly... a rear loop wouldn't help much if the front joint fails.

i got my CHE front loop on. Phew im safe i hope. i saw the carnage of that failed aluminum shaft on MF. scary shit

I've got one loop on my 1-piece driveshaft, and it's in the front. If the rear u-joint fails, the driveshaft will drop down and make a lot of sparks and noise, but won't cause a huge safety issue. If the front u-joint fails and the driveshaft drops down, it could dig into the pavement and either bring the car to a very abrupt halt, or worse, catapult the car. Neither one is a good scenario.

actually mythbusters a while ago disproved the catapult theory. said it was impossible. now i kno nothing is impossible, but it is very extremely unlikely it will catapult the car.

yet i still have my loop on anyway haha the shaft might come through the floor and get me too lol

I saw that episode. The car was too heave to catapult. Going through the floor is a real concern though I think

Haha! I bet you'd flip head over heels if you were running 140mph on the autobahn here in good old Germany! Makes me want to go out and buy a loop for the just because factor...

Well the reason I asked was because the MGW shifter has clearance issues with the BMR front loop.

its a good thing our cars are heavy pigs then

Ah, good looking out my friend!

All you need is 0.350" worth of a spacer between the 2 parts of the BMR loop

BTW - I had a pinion nut fail on a 1985 Dodge 4x4 that caused the 1 piece ds to come apart at the front slip joint. The drive shaft dug into the road and caused the rear end to pitch sideways into the next lane. Luckily no one was next to me.
