I've put together some responses I've received from a few manufacturers regarding bracket fitment when paired with 2.5" shocks.
Synergy Part #8056 - $135.99
Thank you for the email. We have run our 8056 rear track bar bracket with Fox's 2.5" shocks and they do work together. The Kings should be similar. Some factors that may contribute to interference are if the axle has been pushed back with longer control arms, if it has been pushed towards the driver side due to the track bar length, or if the pinion angle is too high. Also, relocated shock mounts can affect this as well.
Rough Country Part #RC1166 $29.95
Unfortunately, we have not tried this so I can not give you a definite answer. Sorry!
JKS Part #OGS170 - $118.75
Thank you for choosing JKS.
I have attached a photo of our bracket with a 2.5" Fox piggy back. I get a little rub at the base of the piggy back mount on the factory track bar bracket that we attach to, but everything else clears.
Teraflex Part #1954776 - $102.59
I do not know if our track bar bracket will clear the 2.5” king shock I believe it will but am not totally sure. It has no problem clearing our 2 ¼” Falcon shocks so I believe it will also clear the king. I have attached some pictures so you can see the clearance.
Edit: Adding Readylift's response:
Readylift Bracket for 3"-4" lift - $34.79
Thank you for contacting ReadyLIFT suspension. To the best of my knowledge we have not tested the brackets with a King. We do offer returns for up to 30 days on un installed product. You could purchase item and hold up to area without installing to determine fitment. Returns are subject to a 20% restock fee and shipping both ways will not be refunded. However this is going to be the only way to determine fitment. Have a great rest of your week. Take care.
