SPL rear adjustable swaybar endlinks are a great upgrade for multiple car models including the Toyota GR86 / GT86, Subaru BRZ / WRX / STI, and Scion FR - S. They come with large PTFE - lined FK 1/2' bearings, offering high load capacity for stiffer aftermarket sway bars. Cheaper alternatives often reduce bearing size, which cuts the static radial load limit and shortens lifespan. The larger bearings here also provide a 22% wider articulation range, crucial for the short overall length. On the sway bar side, custom heat - treated chromoly high - misalignment studs allow up to 65° articulation to prevent endlink bind. Unlike OEM endlinks, SPL ones are adjustable. You can eliminate swaybar preload, set the perfect bar angle, and balance your car's cornering. The solid aluminum mounting replaces OEM rubber, slightly increasing the rear sway bar rate and speeding up response. This results in better handling, more sway bar tuning options, and less performance variation between turns. Benefits include useful adjustability, elimination of swaybar preload, correct install angle, high - strength construction, and self - cleaning, US - made PTFE - lined FK bearings. Materials used are 6061 - T6 aluminum spacers, FK PTFE - lined 65° studded rod ends, and FK PTFE - lined 65° bearings. It replaces some known OEM part numbers, though this list may not be complete due to OEM changes.
Using these SPL rear adjustable swaybar endlinks is straightforward. First, make sure you have the right tools for the job. Remove the old OEM endlinks from your car. When installing the new SPL endlinks, adjust them to the proper length so you can eliminate the unwanted pre - load on the sway bars and set the ideal bar angle. This will help with corner balancing your car. As for maintenance, check the PTFE - lined FK bearings regularly. Since they are self - cleaning, they don't need much special care, but it's good to look for any signs of wear or damage. Also, make sure the solid aluminum mounting stays in good condition. If you notice any issues, like looseness or unusual noise, it might be time to tighten or replace parts. And always keep in mind that the list of OEM part numbers this product replaces may change, so double - check with your car's manual or a professional if needed.
