Done lifted 4x4's for years. Including high speed off road. No problem with joint angles. You kits good but not for those of us that don't wanna remake the floor. Tremec has long fixed the shifting issue.Luck to you too.
For those who choose Tremec there are kits for that.
This kit is for people who choose T56 and don't mind the cutting.
Dropping the engine/trans angle is a wonky solution. Headers fit comes into question, fan to radiator shroud clearance, resulting exhaust ground clearance, aftermarket small block distributor clearance...
That said... IMHO it's pricey for what it is.
I don't see any installation process pictures. Id still want to weld it to the tunnel and the trans cross member that's cut. Who ever puts it in is still going to be cutting and welding.
Could they cut and weld $800 more and make new crossmember (themselves without the kit)? ...Paying a fab shop for 8 hours of labor, probably not. ... at home not paying for your own labor probably so.
