This ground strap from the engine mount to the framerail is the only original part that requires modification during this swap procedure. The strap itself isn't modified, it's simply relocated to allow the K-member's driver-side baseplate to mount flush against the framerail. |  Shane resecures the steering...

While the rack-to-steering-column union comes together without a hitch and the steering wheel is straight, the car will be taken for a wheel alignment once the installation is complete. |
 Unlike some of the other aftermarket...  Unlike some of the other aftermarket cradles, which include tubes that impede or cut off access to the oil filter on a 4.6 (and thus require the addition of a remote-filter setup), PSR has designed more-than-ample clearance for the filter in its Extreme Tube piece. |  The K-member and A-arms look...  The K-member and A-arms look right at home under Shane's Mach 1. While Shane prefers the juice, Dan says the Extreme Tube K-member will support many of the popular turbo systems. We suggest calling PSR to learn more about K-member/turbo-tubing compatibility. |  With the K-member and coilovers...  With the K-member and coilovers in place, the 'Stang's ride height up front is dialed in at stock level to facilitate an accurate comparison between the stock equipment and PSR's Extreme Tube K-member, on the street and at the track. "The new K-member tightened up the car's steering and handling a lot," says Shane. |
We were curious to know the weight difference between a factory New Edge K-member and the PSR Extreme Tube piece.
Prior to installing the new K-member, Dan Boardman checked the weight of both pieces on a scale:
Stock: 107 poundsPSR Extreme Tube: 34 pounds
PSR's new K-member is not only lighter, it's also strong and comes with a free two-year replacement warranty for parts only. "I don't care if you hang the wheels to the moon and slam them back down," says Dan. "If our K-member breaks in two years, we'll replace it with no questions asked."
