SPL Parts 2012+ BMW 3 Series/4 Series F3X Front Tension Rods

The front tension rods, also called caster rods, locate the front wheels fore and aft, and the factory parts do it through soft rubber bushings. SPL's adjustable rods replace those bushings with spherical bearings for a tighter, more direct steering feel. They also give you a wide range of caster adjustment, which helps even out any left-to-right difference.

What you get

• Adjustable caster. A 360-degree rotating clamp locks the setting in once the alignment is done.
• Anti-dive spacers in stainless steel, for tuning anti-dive geometry.
• Gun-drilled 2024 aluminum rods in black anodize, to keep unsprung weight down.
• Teflon-lined FK spherical bearings and rod ends, rated from -65 to 325 °F for street and track use.
• A pair, made in the USA, with blue-anodized titanium screws.

Good to know

• SPL says these do not fit xDrive (all-wheel-drive) cars.
