Price: 210 CAD In stock

Mustang II crossmember kit, for conventional coil-overs. Ships for 10% of the price. Available as a welded crossmember or a ready-to-weld kit.

This is a Mustang II kit for conventional coil-overs instead of stock-type springs and shocks. This lets you use different spring rates and maintain the same ride height by adjusting the lower spring collar on the coil-over. Often the coil-over shock has an adjustable rebound rate, too. Use coil-overs that have a ride height of 11-1/2 – 12”. Use Mustang II tubular upper arms and Mustang II tubular lower A-arms designed for coil-overs and no strut rod. This kit uses the stock Mustang II geometry and track width. The 56” width is used in Fords and Chevs up to 1948 and many other vehicles. Ford F1 pickups should use the 58” kit. Ford F100 (’53-’56) and 2nd series ’54-’59 Chev pickups should use the 60” kit. Set up the front end at the height you want by notching the crossmember and towers to fit your frame. Detailed installation instructions are supplied with the kit and online by clicking the link below.

This unique kit has laser-cut slits that let you fold the crossmember pieces by hand. 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). Anti-dive is built into the upper bracket.

Either manual or power steering can be used and 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 #24410.

These kits are designed to lower a frame. Additional work might be required to keep a frame at the stock ride height.

If you specify a welded kit, the corner-to-corner welds are neat but not ground. The upper towers are supplied flat, because they are much easier to trim before they’re formed.

What appears as lines in the pictures are actually laser-cut slits in the plate. These slits make it easy to form the pieces using an adjustable wrench (for increased leverage).

The holes for the lower control arms are 1/2″ (stock).

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 width is measured at the rotor wheel mounting surface. The width will vary, depending on the brake kit used.

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.

Please note: lower control arm pivot tubes and gussets are not included. Please see the Related Products section below to add a control arm mounting kit, brake kit, or power rack spacer kit.
