The P-47 Crossmember kit is a direct bolt in replacement that was designed to fit 63-87 Chevy Trucks. Not only does it look badass, it narrows your track width a total of 2.25 inches and raises your front suspension 3 inches. This means there is no more reason to “Z” the frame rails in order to lay out flat. Besides, doing a “Z” is extremely involved, very time consuming and unsafe if not performed properly. Not to mention all of the modifications that have to be made when performing a “Z”.
When upgrading your front suspension by using our crossmember, you will ditch all the factory steering components and upgrade to a more responsive and attractive 79-93 Mustang Rack and Pinion. Both manual and power racks can be used. Installing a weld in steering linkage clearance notch is necessary. (This notch is included with this kit). Also, included with this kit are Stainless Steel tie rod connectors and Heavy Duty Teflon Chromoly Heim Joints with Stainless Steel misalignment spacers. These will attach your Rack and Pinion to the spindle.

Q: What is the difference between the P-51 and the P-47 kit?
A: The only difference between the two is how the lower control arm mounts to the crossmember. The P-47 uses a billet clamping block that clamps the lower control arm shaft to the crossmember, while the P-51 has a built in lower shaft with mounting tabs to attach the lower control arm. This option is only given to offer our customers a different look and a choice of how they want their lower control arms to mount.
Q: How big of a wheel/tire will this kit lay out on?
A: This kit will lay a 29.5” tall tire which is roughly a 22” wheel with a tire size of 265/35/22 or a 235/40/22 when using 3” drop spindles.
Q: How much overall lift does this kit provide?
A: Approximately 8” of total lift.
Q: Does this kit move the front suspension forward so that the wheel is centered in the wheel wells?
A: Yes it does.
Q: What engines will this kit work with?
A: We offer engine mounts for the Small Block Chevy, Big Block Chevy, and the Generation 3 Chevy Engines. Any other engine can be used but you will have to build the engine mounts.
Q: How long is this kit under warranty?
A: All of the Thorbecke Brothers manufactured steel products have a life time warranty.
