SPL Parts 04-19 BMW 3 Series/4 Series (E9X/F3X/F8X) Rear Lower Control Arm Knuckle Bushing

If you're working on the rear suspension of your BMW 1 Series, 2 Series, 3 Series, or 4 Series, these rear lower control arm knuckle bushings from SPL Parts are a solid option. They replace the stock rubber bushings that connect the lower control arm to the knuckle with a low-friction, Teflon-lined spherical bearing. This upgrade helps reduce unwanted deflection when you're putting the car under load, and it also allows the control arm to move more freely through its travel without binding.

SPL uses the largest FK bearing that fits in this location, which helps with longevity and can also reduce some of the harshness you might expect from a spherical bearing. The housing itself is machined from 6061-T6 aluminum with tight tolerances, ensuring a precise fit. These are sold as a pair and are made in the USA.
