based on all the link rears i have designed and built...... i believe there is a rotational force being applied to the lowers.The only rotational force would be from braking. every rail has shown me indicators that there is. when i tore this one down i noticed the lower lateral rods had a slight bow to them. straight edge shows about a 1/16" bow. the uppers are straight. i have hit trees and bush's down at LS and that could be the case but both sides are the same. i have seen this on all of them and always the lower. the aluminum laterals were a bad idea though lol i tried it and it failed but.......yep learning curve lol i know you disagree with the rotational forces thought but i cannot deny what i have personally witnessed on my own rails. at this point my only other option is to weld a pivot outside the frame on the rear and add a third point of pivot to the uppers. may do it not sure yet i have a lot to get done yet. the next frame will be about 6" longer for these purposes. spoke to fast this am....intersting to hear how many rails are running megasand trans down there let alone in his group. he actually said all the medi trans had been opened up but none of the megasand trans. have to wait for him to chime in explain that. sounds like the megasands are running turbo 2.5 suby's from out front with his " 400 hp tune"
Like the shock positioning. Now figure out that upper arm...........................
ok so i ordered a digital inclinometer and checked two of my 3 mechanical ones. they are with in.5* of the digital one. Well,that is settled pretty much. Had to be ruled out.i did send back the plunging 930 and asked them to check them as it is not incorrect installation nor over angling them. told them i sell a lot of a arm front end kits and guys swap out to 3x3 trailing arms with longer axles and i have always told them to buy theres but now i cannot do that anymore if an answer cannot be found as to why they don't go 28* as advertised when the cheap chinese $62 ones will go 26* for many many people. Now you sound like me. Maybe you should have held off on that. this is there response..We have tested two CV joints before on a special machine in house and we have reached over 28 degrees. Was that testing done dry? Was it done with a boot flange as suggested below or with no boot flange? This is at a 0 degree horizontal plane with the CV joints offset 28 degrees. This is why we only check the angle on a lathe (How the hell do you set up a lathe with that much offset?)to ensure the CV joint is properly built and the tolerances are held. The cheaper CV joints have different tolerances than our products. Our CV joints are race prepped and polished to reduce heat so the components move more freely inside the housing. I believe when you test this at high angles by dry spinning the CV joint, the components shift because they are so smooth thus they may actually go over the maximum angle. Honestly ,I'm not buying that. When they are in the vehicle at ride height they will not see these higher angles. Really?? BSWhen the suspension droops while driving the car the forward momentum also keeps the components inside the CV joint due to the RPM's.Possibly . Once again if they are below 28 degrees they will be fine. If the angle manages to go over 28 degrees while driving the CV joint will bind and more than likely fail. Duh!Limit straps are used sometimes if higher angles are needed. Also, the use of a boot flange boot adapter will prevent the components from wanting to fall out. Then that info should be plainly stated in the info about them.The only issue I see out of the systems is if you used an over boot CV boot and lifted the vehicle with the suspension drooping. With the high angle and no boot adapter you may see the components wanting to pull out. Ummmm,I don't buy that either.Typically the CV grease is enough to keep them stationary while lifting the vehicle. Also, depending on how smoothly the splines of the shaft move through the inner race, this can determine if the components are being forced out of the housing by the shaft.I can believe that.Please let me know your thoughts. My thoughts are a LOT of covering their ass.
they sent me a video of them testing one in a lathe. doesn't look like 28* down angle but it's a video and it turns just fine they also said the first 6 i returned that they sent by accident turn just fine to so did i get the 4 bad ones out of the ten they sent or what?Pretty unlikely that is the case.
