GPI L86 (6.2) High Lift Truck Cam
These cams are our most popular product, and for good reason – they are pound for pound – the best cams on the market for your 2014+ Direct Injected GM Truck!Although these camshafts were designed with naturally aspirated motors in mind – because centrifugal blowers maintain a very similar, linear power curve as NA – these cams work beautifully with centrifugal blowers. Great option to keep in mind if you are naturally aspirated now – but are later planning on adding boost. We have 4 different iterations of this very popular camshaft – from mild performance increase with nearly stock manners, to all out max power applications.
