Wheelers offers two versions of the Timbren bump kit?

Been looking to upgrade my bump stops for a while now. Happened to see Wheelers is running a sale right now, last day is today. Finally got my ass in gear to research the different options.

Im seeing Wheelers offers two different listings for Timbren bumpstops with u-bolt flip kit. One being almost $150 cheaper than the other (sale price). They both look the same to me other than cosmetic differences and one kit (the cheaper one) having a kick-out in the plate they say is good for adding future air bumps. I know its Monday morning and I haven't had a full cup of coffee yet, so what am I missing here?? Looked through some older threads and didnt see any mention of two differnt kits. Everyone just says the Wheelers kit

 

Im also looking at the Archive kits as well. Either option 2 with Timbrens or option 3

 

The cheaper one is

 

Expensive one has these

 

Those look the same to me. I’d go for the cheaper one

 

Kinda what I'm thinking

That said I am really liking the looks of the Archive yellow kit
