After years of setting records with our S55 and N55 “Lift Kit” camshaft products, we’re now releasing our Gen1 B58 “Lift Kit”. This is an absolutely game-changing product for the Gen1 B58 community! This upgrade consists of a billet OEM spec exhaust camshaft with our custom high lift fuel lobe. Since the camshaft profile is OEM spec, this means there’s no need for upgraded valve springs or any special tuning. Install this with your Dorch HPFP and you get 40% MORE fueling capacity beyond our existing HPFP flow!

NOTE: Once you get towards the upper limits of our Stage 2 HPFP, the B58 fuel system is very much limited by the injectors. In order to see the true benefits of this upgrade, you will need higher flowing injectors.

Gen1 B58 engines have two different versions of camshafts depending on build date. These two Gen1 engine versions have been designated as Gen1 and “Gen1.5”. The link below clarifies the 08/2017 build date cutoffs and which engine your vehicle is equipped with. As always if you are unsure on fitment, simply send us an email with your VIN.
