A word to note, I have stage 5 1400 hp Drive shaft shop ((DSS) axles on my Challenger, they saw 850 wheel, (950 the last year, they’ve been replaced once already and the replacement set rebuilt once as well, pounded out clicking and vibrating CV’s each time. DSS has a new design that they have yet to make public as their wanting to liquidate all of their current design parts first before putting these out there. I have pictures of them and know 3 guys testing them for them. I’d buy Redeye axles before the current design DSS. GForce has their CV’s made for them out of a high grade alloy, hardened, polished, redesigned a few times until coming up with a CV that lasts. GForce uses different diameter half shafts left and right just like the factory does which is their anti wheel hop design, different diameters induce different torsional spring (twist) characteristics to the axles which keeps them from getting in a resonating pattern with each other and reduces the tendency to start hopping, DSS axles are the same part # left and right side. DSS uses 2 piece spline hubs which are prone to run out, GForce uses one piece hubs machined from a solid billet, they run true. I can go on, I’ve done allot of research on axles since being burned with my DSS ones which someday will be for sale, interested in a low miles just rebuilt set of them? Let me know. One caveat to this, I’m a stick, auto’s are much easier on driveline parts, less Shock loading, take that into consideration with your decision what to buy as well.
