Westcott or Eibach springs

Would the springs and a 1/2” Cornfed spacer be a good setup?

 

Seems like you'd be getting 2" from that in addition to the stock bump. So 3" total? Might be fine, but i'd just stick to the springs personally.

 

agreed, use springs to lift and not spacers.

 

Was saying because Westcott spacer lift gives you 2” in addition to your already 1” pro stock suspension, with a total of 3” lift since we’re comparing both kits.

 

After having installed both the Westcott collar/spacer kit, and the Eibach Pro Lift coils on a '23 TRD PRO, I would personally only use the Eibach's.
Options were limited for the '21-23 model years, due to the pigtail configuration of the factory springs that fit the Fox struts, but after installing the Westcott kit, I noted contact points on the coils of both driver and passenger sides while cycling the suspension to full droop. While not a particularly hard contact in the garage on jackstands, in a real world scenario with a heavy tire and wheel mounted, and a sudden drop-out situation, I suspect some damage would be possible to the coils and/or the upper ball joint/UCA. Additionally, the top hat spacer requires that shorter nuts and red loctite be used on the upper strut studs, resulting in fewer threads being engaged, which also made me a little uneasy.
I think the contact problem could be mitigated by "clocking" the springs slightly off from the factory orientation, but if you were to take your truck in for alignment or suspension service, it's likely that the techs would rotate them back to factory position, possibly without telling you. I will also say that I called Westcott directly to see if they had any suggestions for a remedy of the problem I mentioned, but they never returned my calls.
I had no fitment issues with the Eibach lift coils, and they have performed phenomenally.
