That's probably the best reason for moly. Keep in mind if you got a 1' piece 1-5/8" BAR stock in moly and mild steel they would both weigh the same. But since chrome moly is much stronger the NHRA & IHRA allow moly cages to be made of tubing that is 34% thinner than it's mild steel counterpart (.083" wall vs .118" wall) Therefore a moly cage will be 34% lighter than mild.

Two other things to keep in mind - since moly is lighter - shipping cost on the kit are lass but since it requires TIG welding, unless you can weld it yourself , installation cost are bound to be higher.
