Derrick, Give Motoalliance / Viper - one of our sponsors here at the SSW a call. They are great to deal with and take very good care of their customers !! They can answer any questions you may have. I would venture to say that the majority of their sales are with the synthetic cable. The 4000lb is the one that I installed on my 09 RZR.
