Product Details
The Function and Form Type 4 Coilovers for the 2014-2020 Mercedes-Benz GLA-Class (X156) are the brand's premium coilover system, built around an inverted monotube damper for OE-plus refinement and high-end ride control. Engineered to give your Mercedes-Benz GLA-Class a planted, composed feel, these GLA-Class coilovers combine a clean lowered stance with the smooth, controlled damping that makes the GLA-Class X156 feel composed on any road.
Also branded Function & Form / F2 Suspension, the Type 4 uses a large inverted piston and long-stroke design to add travel, cut unsprung weight, and keep damping consistent when you drive hard. One-way adjustable rebound and compression plus full ride-height adjustment let you tailor exactly how the X156 GLA-Class sits and responds, in a bolt-on, preload-ready kit. Backed by a 24-month warranty with free U.S. shipping on orders over $250.
