What is the advantage of using spherical rod ends with a Teflon liner?

The Teflon liner in the FK Spherical Rod Ends provides low friction and smooth articulation, allowing for precise suspension movement. It also offers a high load capacity and increased durability, ensuring reliable performance under demanding conditions.

How do these control arms help with alignment on a lowered BMW?

When a car is lowered, the suspension geometry changes, often resulting in excessive negative camber. These adjustable upper control arms allow you to precisely adjust the rear camber back into the factory or desired performance specifications, correcting alignment issues and improving tire wear.

What is included with these rear upper control arms?

These control arms are sold as a pair, meaning you receive two arms for the rear of your vehicle. They include the gun-drilled aluminum links, clamps, clevises, titanium hardware, and FK Spherical Rod Ends with Teflon liners.

Product Details

SPL Parts is known for making serious suspension components for performance vehicles, and these Rear Upper Control Arms for the BMW F2X and F3X chassis are a prime example. If you're looking to dial in your alignment for track days or have lowered your car and need to bring the rear camber back into spec, these arms are a must-have. The stock adjustment range just isn't enough for aggressive setups, leading to alignment issues that can affect handling and tire wear.

These arms are built with gun-drilled 2024 aluminum for the center links, clamps, and clevises, which keeps them strong while reducing unsprung weight. They use blue anodized titanium socket head cap screws and a unique 360-degree rotating clamp system. This design makes adjustments much simpler than traditional jam nuts; a small allen key is all you need to lock down your settings, and it keeps the bearings properly oriented. Inside, you'll find FK Spherical Rod Ends with a Teflon liner. This setup replaces the soft factory bushings, reducing unwanted suspension flex during hard cornering, acceleration, and braking, which helps maintain your alignment. The Teflon liner is chemically bonded, offers low friction, smooth articulation, and a high load capacity, all while operating reliably from -65°F up to 325°F, making them suitable for both street and track use. These are sold as a pair and proudly made in the USA.

This set is designed to fit a wide range of BMW models including the 2 Series, 3 Series, and 4 Series from roughly 2010 through 2021. If you're serious about getting your alignment dialed in, these control arms will give you the adjustability you need.
