Cobb Rear HD Sway Bar Endlink Set – Subaru WRX / STI / FXT (CB-3915K)

The COBB Rear HD Sway Bar Endlink Set (CB-3915K) is a heavy-duty upgrade designed to improve rear sway bar effectiveness and suspension response on select Subaru models. Constructed to handle higher loads than factory endlinks, this set reduces flex and deflection, resulting in more consistent sway bar operation and improved handling during aggressive driving.

The COBB CB-3915K rear endlinks are ideal for vehicles equipped with aftermarket or stiffer sway bars, providing increased durability and sharper rear-end response for both street and track use.
