I liked this product. I didn’t need all the bolts just half of them to get the job done. Well worth the money

Fits the LS2 throttle body just fine. The longer bolt is what I used but overall I’m happy with it even though I don’t need the short bolts. Like I said fits the LS2 throttle body on LSA SC.

Will not work on drive by wire applications like LS2/LS3, please change the description. Bolts are too short. Most ICT stuff is fantastic, these not so much.
