Vented Transmission Top Cover, Black - Milwaukee 8
The Trask CheckM8 Vented Transmission Top Cover – the ultimate solution to the common problems faced by Harley-Davidson M8 engines. Free up your engine with this upgrade designed to address excessive oil consumption and blow-by issues.
Our patented design features a one-way Boyesen reed valve, designed to bleed off excess crankcase pressure. This innovative design ensures optimal efficiency by venting excess pressure from the crankcase whilst keeping oil/air mist in the cam chest, thus allowing the oil pump to function more effectively. Experience a significant reduction in oil exiting from the head breathers, leading to enhanced engine efficiency and easier revving.
Machined from lightweight and durable Billet Aluminum, the Trask CheckM8 not only provides unparalleled performance but also boasts a clean and sleek look. Proven on our Trask Performance Race Baggers, the Check M8 has proven itself repeatedly to withstand even the harshest riding. All you have to do simply is replace your stock transmission cover with our Check M8 to notice a world of difference with your engine.
Take your ride to the next level both in performance and looks with our American-made Check M8!
