Re: Light Racing UCA installed w/Pics
ToledoFJ called us and let us know this thread was flowing. Here are a few deign points on our Upper Control Arms you all might be interested in knowing:
Our Upper Control Arms were designed work with a wide range of coilover shocks; from the stock Toyota units to long travel aftermarket shocks similar to the Light Racing or Icon units. This includes shocks that allow for a slight increase in droop travel.
The increased travel was accommodated by using a ball joint with a higher range of travel. The stock Toyota ball joint has a 77° included angle (or 38.5° off centerline). Our design allows for a 90° included angle (or 45 ° off centerline. A spherical bearing (monoball) with high angularity inserts rarely has more than a 35° included angle. The angle of the ball joint plate is optimized for this increased ball joint travel.
The sliding off-set ball joint that we use allows for a huge range of alignment adjustment rather than designing an arm with a static off-set and relying on the Lower Control Arm cam bolts for adjustment. This means the camber of our arm can be adjusted to the stock upper control arm geometry or it can be adjusted for proper camber in a 4 lifted vehicle. The caster can also be adjusted from stock numbers up to a 4° increase in caster for better high speed stability.
Using a standard ball joint (instead of a monoball) and molded rubber inner pivots (instead of urethane) gives better ride quality, better longevity, lower maintenance, and quiet operation.
We as a company have 30 years experience designing ball joints for aftermarket and OEM use. The design and quality of the ball joints used on these arms is top notch.
Our arms are coated using E-coating. This is a process where the coating is electro-statically grown on the part. This is used for many OEM suspension components and gives superior corrosion protection to zinc plating, paint, or powdercoating.
I will check this thread a few more times over the next couple of weeks and answer what questions I can. For other questions please call our customer service department at (800)525-6505.
