I have a 2007 RCSB Tundra and i have installed the Mcgauhys 2/5 kit. I did 2in spings in the front and flip kit in the rear. I want to upgrade to the 4/6. I read on the forum where JeepNuts and Its Jason Thomas have done this but have a few questions.

If i put my stock shackel back in with the flip kit in the rear i will have 6in in the rear right?

For the front just buy and install 2in drop schakles?

I will need to notch the tranny corssmeber for the driveshaft also? I saw Jasons pics.

What about a C notch on the frame in the rear? Im worried about that i read if you go 6in in the rear u need a c notch.

Last thing what are you guys running for rear shocks?

Thanks guys i really wanna get down to a 4/6

I think you need the 2" drop spindle kit for the front which McGraughy sells.

The only C notch I know of is the bed cross member. The driveshaft will hit it if you do the 6 inch drop in the rear...

You should really do the C notch regardless of the lowering height. Even at 2/4, my drive shaft was hitting when i went over bumps and now has some pretty ugly groves in it. I ended up getting it done as well as changing my rear shocks. the shocks that come with the McGaughys kit are super cheap. I switched over to ground force shocks and it was night and day. I also had to change the driveshaft seal as it became oblong from the driveshaft hitting the crossmember so many times.

***SIDE NOTE*** there are wires that are ran in the inside of the cross memeber channel that needs the C notch. Move them aside or tell the mechanic thats doing the notch about it so they dont cut into/through the wires. They are not visible from underneath. The guy that did my notch was using a torch and almost melted the insulation.

Are you guys not notching the frame at 6in drop in the rear. I put my stock shackles on Saturday so im down to 6in in the rear and i hit my bump stops alot now. I knew about the crossmember notch and i will be doing it soon. I am just worried about clearence between the frame and axle in the rear. On the crossmeber is everybody notching it in the truck or can you pull it out and do the notch.

Also how big of a differnce in ride is the 4/6 compared to stock. I will love the look of the 4/6 but i want the truck to still ride good (no hitting bump stock or rubbing driveshaft.)

I had my notch done in place. we had to drop the drive shaft to make it more accessable. My mechanic also welded in a piece on the inside for added strength. I think pulling out the cross member would be a lot of work and more stuff would have to come out first to get to it.
