hoseline Posted January 7, 2008 Share Posted January 7, 2008 Does anyone out there have some hard evidence on drive axles for sand cars. I have a sand car 450 hp LS1 with 2D trans and have drive axles from Jesse @ highangle drive axles. Only have about 150 gallons of fuel through car and found that the side plates of trans have cracks already???? any help on why or experiences would help, probably should go to CV's :porn: Quote Link to comment Share on other sites More sharing options...

barefoot bob Posted January 7, 2008 Share Posted January 7, 2008 (edited) i have extreme drive axles 2 seasons no problems. i have heard of alot of people having problems with jess's axles that battle goes back and forth. i have heard alot of bad about extreme cause of the sheer plate bolts. jess doesnt use them but those things are as strong or stronger than 934s which means the energy is transfered as load in the tranny. and 2 ds are already not as strong as they should be. so instead of a cv giving out the tranny bears the load. this hole mess boils down to angles proper cvs and load. if you are having 930 cvs break alot there are some determining factors like did you measure the angle with the car jacked up in the air?? if your over 23 degrees at full droop 930s are gonna blow. the fix , set your limiting straps to not allow droop past 23 degrees quality cvs, peolpe like gearone are producing a 300m cv. problem is its only about as strong as a chromeolly cage from a reputable dealer. there are other problems out there like offset angle from trailing arm to tranny where if its extreme driveline axels could help. there talk of concentric vibration in the drivelines. and of course tourqe. big tourqe will kill a 2d or 930s. and of course the way your driving like sidestepping your clutch ect ect. the 300m is a treatment process not a metal content as it was explained to me. inferior metals are a cause of a weak cv a good set of race prepped cvs from someone like kar tek in 300m are usually about as tough as your going to get. couple that with proper angles and youll have a good set up. drivelines seem to take more angle the trade off is more load on the tranny. 2ds dont like this 934s are the same they put to much load on a 2d the sheer plate system from what ive studied and heard and read is still yet unperfected some are good alot are bad.( the grade 3 bolts sheer prematurely. so now they mix them with grade 8s to try to find a combo) they need to re tightened every trip and monitered.thats alot of work imo i still favor 930s with proper angle and quality cvs . just cause there 300m doesnt mean they are quality. we spent the last 4 years on jameses ( fasterdady) ricochete car trying to figure this out. we finally found the perfect combo. 22degrees angle at full droop and a proper set of cvs. no more trouble. if you dont have limiting straps you should have them.

SandBox_Kid Posted January 7, 2008 Share Posted January 7, 2008 There is speculation that during load the splines fail to plunge when necessary....... Quote Link to comment Share on other sites More sharing options...
bp-guy Posted January 7, 2008 Share Posted January 7, 2008 I almost went with those on my car, glad I saved my money and trans at the same time. Granted I have only 300ish horsepower but I would be very upset to blow a tranny rather than having a cv go BOOM! Quote Link to comment Share on other sites More sharing options...
predu Posted January 8, 2008 Share Posted January 8, 2008 yes the sheer plate bolts always come loose , and i got tired of breaking the bolts so i run all grade 8.i have 450 hp and a 4e no problems yet. but that is just my susp setup not all are the same, different angles and geometry (sp?)

Yoshi Posted January 9, 2008 Share Posted January 9, 2008 Does anyone out there have some hard evidence on drive axles for sand cars. I have a sand car 450 hp LS1 with 2D trans and have drive axles from Jesse @ highangle drive axles. Only have about 150 gallons of fuel through car and found that the side plates of trans have cracks already???? any help on why or experiences would help, probably should go to CV's the 2D tranny case is cast, cast is weaker, some people have broke the exact same case multiple times with cv's. The problem isn't with jess's axles only, it's u-joint axles. Splined slip shafts don't plunge quite as smoothly, which puts a little more load on the inner trailing arm mount, and the side case of the tranny. If you have good tabs for the inner trailing arm mount, and the covers on the side of your tranny are not cast, you will be fine. Everyone that has broken a tranny ccase had a cast cover, others have been running them for quite a few seasons with no problems and they have had no failures. The 2d is a good tranny, but it is one of the weaker brands to my knowledge, and the only tranny that is having issues with u-joint axles in general.... All the ripped out tabs that have been posted were rather thin, and not braced properly... Quote Link to comment Share on other sites More sharing options...
