Message from Light Racing on Upper Control Arms Hi All,
Specialty Product Company (SPC) and Light Racing felt that it would be appropriate to chime in regarding our control arms and some of your discussion.
Objective: The objective for the Light Racing / SPC front upper control arms for the 4Runner, FJ, and Tacoma was to provide you with an option that delivered:
• Significant Camber and Caster change that would correct ride quality and tire wear issues for a wide range of lifts and uses
• More articulation than the OE ball joint
• More clearance for the spring and tire than the OE arm
• OE quality ride with rubber bushings and OE style ball-joint assembly that would never require service
• Higher strength than the OE arm for extreme off-road use
• All the above for a very reasonable price
Issues: As you have been discussing, we have had a couple of hiccups that did not get caught during our quality reviews and product testing.
1. Our 1st batch of ball joints did not perform as designed. Though the ball joints assembled fine and appeared fine from the outside, under full articulation they were binding internally.
2. Our 1st batch of bushings did not permit enough compliance for the articulation that these arms can see in the field. Therefore, there is a possibility that these bushings could fail prematurely.
Fixes: There are two types of fixes that we need to address;
1. First, and most importantly, we want to stand behind the product that is on the street. If you believe that you have arms that have bushing or ball joint problems, we want to hear from you. Please call us at 800-525-6505 to determine next steps.
2. Second, product shipping now has been corrected.
• The root cause has been determined and corrective actions taken make sure that the ball joint perform as designed. Additionally, quality control is testing ball joint articulation on every batch.
• We have completely redesigned our bushings to improve the compliance issues that our 1st batch experienced. We have both decreased the durometer of the rubber and increased the compliance in the bushing design itself. (see photos)
We at SPC and Light Racing are disappointed ‘not to design intent’ product that we unfortunately allowed to get into the field. Please be assured that these issues have been resolved and that we will always stand behind our product.
As for which arms to buy, obviously we hope that you will strongly consider our arms, they do achieve our original objectives. Yes, Total Chaos and Icon are both quality companies and our friends. Each of our companies offers different features and benefits for you to choose from at different price points. Your patronage for any of the three of us is appreciated.
