Street or Track Tubular +Caster Upper Control Arms (1965-1973 Mustang)

Description

These arms are shipped with 3 degrees of positive caster dialed into the adjustable heim bearings. More caster is achievable by threading in or out the heim bearings. Track width can also be adjusted.

For our pivot we use a chromoly, heat treated heim bearing. Metal to metal support on the ball to body can handle heavy shock & vibration loads and has a increased cross-sectional thickness for greater tensile strength. This bearing is the big brother version we’ve used for many, many years of trouble free service in our Adjustable Strut Rods. Surprisingly this bearing doesn’t increase harshness like you would think, instead, it improves the ride quality by transmitting any road irregularities into the shock and spring for those components to soak up the bumps.

This type of bearing not only offers bind free operation, but as an added bonus the threaded section can be used for adjustment to change the length of both control arms. By adjusting the length of both control arms for alignment and minimizing the stack of shims used to compensate for chassis variances, a more rigid connection to the shock tower is achieved.

We built these control arms with performance and handling in mind.  If that means it takes longer to set the alignment because both UCA’s need to be the same length then so be it.  Your lap times or freeway on/off ramp outings will benefit.

Bottom line…

We’ve developed a rigid, stiff, rebuildable set of control arms that fix the stock control arm positive camber characteristics.  Combined with the large range of possible camber/caster settings these control arms offer something for the weekend street cruiser to the drag or road race Mustang owner.

Specifications & Benefits Short List:

• Shortened arm and angled ball joint plate increases camber gain.
• Tubular design makes for a lightweight, rigid structure.
• .156 Wall seamless tubing.
• TIG welded construction.
• Shipped with the front bearing 3 turns further out than the rear.  This adds approx. +3 degrees of positive caster to the spindle when installed before having to shim the front bolt or shorten the strut rod.  More or less is easily possible by simply adjusting the bearings in or out. Our shop ’70 Mustang easily runs +7 degrees of caster with our Tubular Lower Arms & Strut Rods.
• CNC machined, steel/plated cross shafts – no weak aluminum drop shafts for us!
• Moog ball joints, bearings and all nuts and bolts are replaceable ‘off the shelf’ components making these arms easily serviceable.
• Durable powder coated high gloss black finish.
• UCA accepts stock spring perch or rollerized perches.  No need to drill or weld and re-drill new mounting holes as these are compatible with stock, 1″ drop or 1-3/4″ drop holes.
• Sold as a pair and shipped fully assembled with detailed installation and alignment instructions.
