SPL Parts 2012+ BMW 3 Series/4 Series xDrive F3X Front Caster Rod Bushings (Non-Adjustable)

If you're looking to tighten up the front end of your BMW 3 Series or 4 Series xDrive model from 2012 and up, these caster rod bushings from SPL Parts are a solid option. They replace the stock rubber bushings with spherical bearings, which means less flex and more direct feedback from your suspension. This is especially noticeable when you're braking hard or making quick steering inputs, helping to maintain your suspension geometry under load for improved control.

SPL uses large, 1-inch FK Racing Bearings with self-lubricating Teflon liners in these bushings. This setup is built for performance and durability, and it's made right here in the USA. While these specific bushings are non-adjustable, the design aims to eliminate deflection and reduce friction, giving you a more connected feel to the road. Keep in mind that the original control arms are not included with this kit; you'll be replacing just the bushings themselves.

This kit is sold as a pair and is designed to fit a range of BMW xDrive models, including popular choices like the 2015-2016 BMW 228i xDrive, the 2013-2018 BMW 320i xDrive, and the 2014-2016 BMW 428i xDrive. If you're aiming for improved handling precision and a more responsive feel from your BMW's front suspension, these bushings are a worthwhile consideration.
