Heidts KX-101-E Universal Mustang II Crossmember 56.5 Track Width

Using this Universal Multi-Fit Mustang II Crossmember Kit, you can now adapt the very popular Mustang II suspension with HEIDTS correct geometry into almost any application. The crossmember and spring towers are made oversized to allow trimming and fitting to your particular frame size. Templates and instructions, designed for a home builder to install, walk you through the entire installation to insure that you get correct anti-dive and geometry. 

• Designed to fit frames with outside to outside frame widths of 24" to 30"

WARNING: This crossmember design is now updated and is designed to only accept and work with strutless type tubular lower control arms.  It will not accept nor work with the o/e type stamped lower control arms.

• Finished track width will be 56-1/2"(hub to hub)
• Constructed of 7-gauge steel
• Mustang II cross members using stock spindles will drop the stock ride height 3-4”
• One-Piece Shock Cups are T.I.G. welded in place and have anti-dive built in. First class, for your car.
• Vertical Inner Uprights.  This is the strongest design available, with twice the weld area.  This will keep your frame from twisting!
• Main crossmember made from only 2 formed pieces for maximum strength and accurate fit.
• Works with both manual or power rack and pinions
• Features a raw welded finish

WARNING: This is a universal crossmember to be used with Mustang II style components. It is NOT designed for any specific car or truck. You will need fabrication and welding skils to complete the installation.

• Additional items may be needed to complete installation.  You may want to include our Mustang II ride height adjusters (91034444) for installation with these crossmembers to fine tune your final ride height up to 2".
• When using this crossmember with our "power" steering rack, you may also need (2) rack spacers (9101023). (These spacers are included with our Mustang II suspension kits.)
• Applications where the vehicle has fenders that mount directly on top of the frame, the fenders will require extensive modification to allow clearance for the upper cross member section.
• Complete installation may require you to purchase corresponding a-arms, shocks, springs, brake kit, spindles, and steering rack and pinion.
