Fathouse Performance S550 Antigravity Battery Kit (No Catch Can) (FP-S550-ABK) - 2015-2023 Mustang
Drop serious weight from the nose of your S550 Mustang with the Fathouse Performance Antigravity Battery Kit. Designed for racers and street builds alike, this kit swaps the heavy factory battery setup for a lightweight Antigravity-style lithium mount, freeing up valuable pounds where it matters most for handling and ETs.
The FP-S550-ABK mounts cleanly in the OEM battery tray location for a factory-style fit, while supporting the Antigravity ATX-20HD Lithium Ion battery. It’s a simple, bolt-in solution built to save up to 30 lbs compared to stock, helping your Mustang accelerate, brake, and turn harder. This version is intended for setups that do not need a catch can in that area. Battery is not included, so you can source your preferred Antigravity unit.
