Description
This direct-replacement Front Hood / Bonnet Gas Spring Lifter (Stay Shock) is engineered specifically for BMW 1 Series, 2 Series, 3 Series, and 4 Series (F-chassis range) vehicles built between 2010 and 2021. Precision-manufactured with a seamless, corrosion-resistant steel pressure cylinder, nitro-carburized piston rod, and high-durability internal multi-lip seals, this gas damper provides optimal lifting force, smooth controlled damping, and reliable hold-open support for the engine hood. Designed to exact factory dimensions with OE-style ball-socket end fittings, it allows for a quick, clip-on, tool-free installation to replace worn-out or depressurized bonnet shocks that fail to support the engine hood.
