Mustang II Crossmember Kit, for Coil Springs

SKU WS14340
In stock
Product Details

High quality and low cost is achieved by using this Mustang II crossmember and upper tower kit. Set up the front end at the ride height you want! Detailed installation instructions are also online by clicking the link below. Either manual or power steering can be used- the passenger side mount has a slot to take the later model power rack. As with all Mustang II aftermarket crossmembers, spacers must be used with the later (Fox-body) power rack. These spacers are available from Welder Series as #24400. Use stock control arms or aftermarket upper and lowers with this kit.

Most vehicles will use the standard 56” track width. 1942-52 Ford pickups should use the 58” kit. Ford F100 (’53-’56) and 2nd series ’54-’59 Chev pickups should use the 60” kit. If you specify a welded kit, the corner-to-corner welds are neat but not ground. The stamped shock mount is TIG welded in place.

What appears as lines in the pictures are actually laser-cut slits in the plate. These slits make it easy to form the piece by hand, or, in some cases, by using an adjustable wrench to get a better grip on a small tab. Rack mounts are incorporated into the crossmember design and rotate the rack back 20° to get the input shaft lower. Stock, manual or power racks or later model Mustang II or T-Bird power racks can be used. The later power rack will require the Power Rack Spacer and longer bolts, as described in the power rack mount spacer section. The rack is positioned so the bellows will clear most aftermarket full A-Arms (such as Heidt’s, Total Cost Involved, Fatman, etc).

Stylish, cone-shaped stamped upper shock mounts also function as the coil spring locator. The upper towers have anti-dive built in. The holes for the lower control arms are 5/8". Installation instructions show how to set up the front end at the ride height you want. Rack extenders or Fairmont tie rod ends must be used on 58″ and 60″ kits. Crossmember & upper towers are made from 3/16″ mild steel. The track width is measured at the rotor wheel mounting surface. The width will vary, depending on the brake kit used. Please note: lower control arm pivot tubes and gussets are not included.

Track width is the rotor wheel mounting surface to surface dimension. Welder Series makes 3 widths: stock (56″), and 2″ and 4″ wider (58″ & 60″). These are nominal dimensions. With stock, 4-bolt MII rotors the actual track width would be 1/2″ wider than our listed spec, but the final track width is dependent on the control arms, wheels, and brake system used. An easy way to estimate the stock track width is to measure tire tread center to center.
The outside frame width is less critical than track width, but is a consideration. Our 56″ kit likes a frame o.d. of 26″ – 30″. The 58″ kit likes 28 – 32″ and the 60″ kit likes 30 – 34″. If the frame doesn’t correspond to these dimensions, there are work-arounds that we can suggest.

  1. Can I use Duralast Wires? I just bought some not to long ago, and I was wondering if I could just switch out the terminal ends and use those.

  2. im very interested in purchasing this upgrade,
    I have a very bad issue with my VR6, it turns over run for like a minute idling extremely rough and then shut down, I can maintain it on by playing with the gas pedal,
    anyways researching came across a lot of the same issues with people, not as bad as mine but the same, and in these case people do suggest coil pack failure, and then I see a best solution is this MSD upgrade.

    any suggestions.

    1. I can’t guarantee that this upgrade will solve your issue, but it will help it to run better once any other issues are addressed. Have you inspected the coil pack for cracks?
      Thanks for writing.

      1. Thanks for the reply, I actually need to do too end rebuild the previous owner ran it hot for a while and I think he warped the head so im going take care of that first but I will be done that upgrade regardless I’ve heard excellent things.
