MEYLE Lower Control Arm for Porsche 911, Boxster, Cayman, and 718 (1997–2024)

MEYLE part 416 050 0029 is an updated-design lower control arm for the Porsche 911, Boxster, Cayman, and 718 Boxster and Cayman. It links the wheel carrier to the subframe and pivots as the suspension travels over bumps and through corners. Porsche revised this arm by combining the 43 mm bushing size with a 991/718-style lower arm. The ball joint sits at a 20° angle and allows 40° of movement. MEYLE builds this arm in Turkey.

For warranty coverage on this part, contact your dealer.

This is the revised arm, not the earlier version, and that affects how you order. If the arm on the other side of the same axle is the earlier design, plan on replacing both. Cars from the 986 Boxster and 996 911 generations also need a matching lateral arm, which is covered in the installation notes below. You can check the arm against the one on the car with two measurements. It is 286.1 mm from the center of the inner bushing to the center of the ball stud. It is 220.6 mm from the center of the inner bushing to the center of the outer bushing. MEYLE has supplied parts from Hamburg, Germany, since 1958 and now ships to more than 120 countries.
