Trailing arm or A-arm? Trailing arms have a lot of plunge, splines alone will not provide all the plunge you need. The CV flanges would also need to be 2-3" deep and very large in diameter to clear the axle as the suspension cycles.A-arm, your golden.
I'm planning a new project and need input. I am going to use a Polaris sportsman transmission. I want to use VW axles and cvs from a 1986 Jetta[90mm inner].I am trying to keep rotating weight down. I have long splined after market axles. Will these work with the outer fixed cv? Could an adapter be machined to adapt the VW cv flange to the Polaris transmission[ a large splined shaft with small splined shafts on each side]? Can I overdrive the transmission 2 to 1 ? Let the discussion begin. Tim
