Built to endure any challenge, our ADF Trailing Arm Spacers are specifically designed to correct geometry changes associated with strut spacer, lift springs, and lower lift bracket lift kit installations. These corrections include caster adjustment, wheel-centering, and elimination of radius rod bind, ensuring your Subaru maintains its excellent handling characteristics, even in stock form. Manufacturing Details: For unmatched strength and durability, our Trailing Arm Spacers are crafted from 3/16” steel, laser-cut and MIG welded to ensure the highest levels of precision and reliability. Factory Alignment Preservation: To maintain factory alignment specifications, Camber and improved Caster offsets are intricately built into the steel spacers. However, we recommend getting an alignment post-installation to account for any potential discrepancies during the installation of camber bolts. Benefits of Trailing Arm Spacers: Installing trailing arm spacers is highly recommended. They keep your tires centered in their factory position and prevent rubbing when fitting larger tires. Compatibility Note: Please note, these spacers are not compatible with Multi-Link suspension designs.
