Our Rear Upper Control Arms (Camber Arms) take everything we’ve learned from motorsport and road car performance for over 15 years and apply it to the Tesla Model 3 rear upper control arm. We know how important it is for suspension arms to be easy to adjust, have great durability even in harsh climates, and have solid bearings rather than rubber bushings for the ultimate connection to the road.
Most aftermarket suspension arms are made using either urethane bushings, which are used because they are cheap – or spherical rod ends, which are ideal for performance but don’t last very long in sandy or salty environments. Our solution is to use an OEM production sealed bearing – delivering the performance of the spherical and the durability of an OE part. The sealed bearing is just like a ball joint, it is solid and has virtually no compliance, while being lubricated and protected from corrosion.
Rod ends tend to thread into a suspension arm, which makes them very easy to adjust – whereas a pressed in bearing offers no adjustment. Our solution is to use a threaded turnbuckle allowing for precise adjustment. Rather than use jam-nuts – which always affect the alignment when locking down the nuts – our clamping system allows the alignment technician to perfectly set the alignment, then tighten the clamp bolts without throwing off the camber.
The turnbuckles are made from stainless steel, as are the bolts and nuts – so they will never corrode or rust. The arms are CNC machined out of 6061 aluminum, and anodized blue for durability and aesthetics.
These arms come fully assembled at set to the factory length. We always recommend using anti-seize lubricant to prevent any galvanic corrosion between the aluminum and steel. Camber adjustment range is as much as you’d ever need for any ride height or reasonable desired camber setting. Arms come as a pair of two and are warrantied for three years from the time of purchase.
