I talked to them last week, they said 1-2 weeks and they'd be done with durability testing for the new units and shipping them out to those waiting on the replacement pieces.
Adjustable Uca's are for lowered cars with one piece shafts that have no cv joint at the rear. With the dss cv joint in the rear you don't need an adjustable uca. Besides the roush unit can handle a 1 inch drop with a regular aluminum d/s because thats what their suspension package comes with! Anything beyond 1.25 inches requires and adjustable uca on a regular aluminum d/s!
Im running the Tokico 1.5" Drop springs with stock DS & Stock UCA. (adj LCAs)
Is this a major issue that I need to address now or can it wait!?
Will these use the same old mounting bracket?
Hey everyone,
I wanted to bump this thread with very promising news! Whiteline recently contacted us about their revised UCA and sent us a sample of the finished product. This new Whiteline UCA benefits from a thicker steel and additional bracing to endure whatever you can throw at it. I think you guys will be very pleased with updated UCA.
Whiteline has a large shipment of these revised UCA's headed our way, too. Starting no later than 10/17/2013, all of our Whiteline UCA's will be swapped out for the revised version!
Also, I took some cell pics of the revised UCA, so you guys get a sneak peak!

Looks like they still might contact the diff on lowered cars. Have you guys thrown one on a car to see if this is the case?
Our design simply does not require any thrust washer to retain the bushing. Having that on our unit is just useless. Since we manufacture our own bushings, they were made to exact sizes and dimensions. Skewing logic and misinformation :nono:From a busing perspective, the other brand's synthetic bushing employs a pinhole voiding feature and lacks a thrust washer to properly retain the bushing within the structural housing. The construction technique results in reduced structural durability and integrity in the long-term and is prone to excessive NVH (Noise, Vibration, Harshness) characteristics as it wears because it lacks overall structural durability and integrity.
The Steeda bushings we use in our upper control arm are a special proprietary three-piece design (see image below) we engineered and competition tested to enhance performance and reduce NVH.. We strategically integrate a thrust washer to secure the bushing, further increasing structural integrity and providing reduced slop. Designed for demanding use on both the street and track, our part has been extensively tested on our race cars under the most severe conditions possible.
Going to the softer bushing will reduce the nvh but sacrifice control. Our bushing durometer gives you the best trade off of handling vs nvh.
Best Regards,

You should have sufficient clearance. See below:Looks like they still might contact the diff on lowered cars. Have you guys thrown one on a car to see if this is the case?
You are more than entitled to your opinion and preference; however, your logic is a bit skewed. In terms of pinion angle, each design has its strengths and weaknesses. The use of the eccentric crush tube allows for uniformed strength and durability along the entire arm. The weakest point then become the welded ends, as it should. There are no welds or nuts in the middle of the arm or adjustment piece that absorbs the torsional loads. The arms wall thickness remains constant throughout the arm length - our design eliminates the need for weld bungs and thin wall thicknesses required to adapt it nor does it require additional manufacturing steps thus cutting down manufacturing variability.Pinion adjustment on the whiteline is an absolutely horrible design. I dont like to slam peoples products but from having owned this piece first hand it isnt worth owning. Simply look at the process for pinion adjustment with this UCA and it is laughable. Really if I would have known what I was looking at before I bought mine I never would have. Any guy that has been modding RWD vehicles in the past should see this immediately. My 14 GT is my first RWD vehicle so I had no idea.
Also mine was hitting my rear end and creating a humming noise. They did not change the design at all to correct that.
