GPI L83 (5.3) 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.
cam options
STG1
Cam Specs:
212/226 .630/.630 114+8
Designed to work great with a stock torque converter and no milling on the heads, offers stable idle, excellent low end torque, and smooth lobe design for quiet valve train operation and longevity. We designed this camshaft for use in trucks with minimal modifications. Requires a GPI 4* Phaser Limiter.
STG2
Cam Specs:
215/230 .630/.630 114+4
Tailored for the street / strip individual that runs a 3000+ RPM converter. It rivals the torque output of the STG1 but packs on about 10-15 additional horsepower up top. Strong to 6400 RPM. Requires a GPI 0* Phaser Limiter.
STG3
Cam Specs:
219/231 .630/.630 114+4
This is the perfect cam for the hardcore enthusiast, and makes more torque and horsepower than our STG1 and STG2 cams. Very strong to 6600 RPM. Requires an upgraded converter, as well as a GPI 0* Phaser Limiter.
STG4
Cam Specs:
223/235 .630/.630 114+8
Our strongest 5.3L DI Truck Cam, the STG4 is an all out performance application for maximum power. Very street able, requires 4000 plus converter, and requires flycutting. Strong to 6800 rpm. Specifically designed to utilize the GPI 4* Phaser Limiter.
