Guys, I wanted to announce we are discontinuing the SBD400X kits starting August 1.
The 500X provides more HP on pump gas, a stronger ball-bearing CHRA, can be used on stock fuel system....and has 400X like spool for strong midrange torque.
I don't see ANY downside, so we've decided to make it the solo option moving forward.
The good news is, we will be stocking them in our Oklahoma Distribution Center for same-day shipping. (Trying, as demand has been heavy and we may run out from time to time.)
Zage has been extremely generous in agreeing to some aggressive pricing to us, in order to make this feasible.
So moving forward, the SBD500X kits will be at the $2999 price point
