Thank you.no. Differential != IRS
The Steeda and BMR differential bushing 'insert' kits use a high durometer material to 'sandwich' the Ford soft/flexi-rubber. The Whiteline uses a softer material and thus less vibration pass-thru. Unfortunately Whiteline appears to have discontinued their kit that totally replaces the Ford bushings. That's the one I put on 2 cars and it's lovely. The next closest thing is one from Energy Solutions but I can't speak to durometer of the materials.
The Steeda IRS support/lockout you referenced is akin to this Whiteline kit.
