Fall-Line Motorsports Aluminium DCT Hydraulics Cover – the must-have BMW DCT upgrade
Upgrade your BMW dual-clutch transmission with the Fall-Line Motorsports Aluminium DCT Hydraulics Cover. This premium billet 6061-T6 aluminium DCT hydraulics cover replaces the weak OEM plastic cover that is known to fatigue and warp from repeated heat cycling. Engineered for reliability, cooling and long-term sealing, it is the ideal BMW DCT performance upgrade for road, track day and motorsport use.
Designed and manufactured in the USA, the Fall-Line DCT hydraulics cover is 5-axis DMG Mori CNC machined for precision, hard-coat black anodised for wear and corrosion resistance, and finished with functional external cooling fins to help manage heat and reduce the risk of dreaded DCT overheating errors. A bespoke Viton O-ring sits in an internal channel for a consistent, leak-free seal that eliminates the flimsy OEM gasket and the need for regular replacement. Viton offers outstanding resistance to temperature extremes, with an operating range of -20°F to 400°F (about -29°C to 204°C), and exceptionally low gas permeability for long service life.
If you already run or are considering the Fall-Line Ultimate DCT Oil Pan, this matching Ultimate DCT Hydraulics Cover completes the package for maximum performance and durability. Together they deliver a robust, cooling-focused solution for your BMW DCT transmission.
