Hello, i'm wondering what the difference between these two sway bar kits is, both are listed as accessories for my Slayer Pro

Kit 5998 which is $30

Kit 5496 which is $10

I'm assuming there is a difference of some sort for a difference in $20, just not sure what that difference is is all.

Thanks in advance!!
