Hey Bryan, thanks for the information! It looks like the Big Tex 70CH trailers have a pair of 3,500 lbs axles. These are typically 2-3/8" in diameter, which means you'll need two of the Dexter Trailer Springs Over-Under Conversion Kit item # K71-384-00. This kit is sold individually so you'll need one per axle.
If for some reason you have 3" diameter axles you'll need the item # K71-385-00.
Why are you wanting to lift your car trailer? This is definitely the first time I've seen someone wanting to do that.
