You asked for it ! So it's finally here "Power with LOW MAINTENANCE"

Now you can finally enjoy the power and rpm potential normally only associated with solid flat tappet cams without the need to adjust tappets.

We are always asked for engines with more power and less maintenance at an affordable price. It's taken a lot of R&D at Pavtek over the years to be able to bring this to fruition.
We all know the use of hydraulic roller cams brings the best of both worlds, great power with low maintenance, but being able to stay in control of the valve train without the use of ultra lite weight expensive components at high rpm has been very challenging, but it's finally here in the way of our new "Silver Accelerator HR Race Series" Now you can enjoy more power and rpm without the concern of "wiping a lobe" and the need to adjust tappets normally associated with solid flat tappet cams.

Most Power, but with High Maintenance.
Whilst aggressive solid roller cams will still always make more power many people aren't too excited about having to adjust tappets and also swap out their roller lifters on a regular basis due to the massive spring pressures normally associated with solid roller cams. We think our new "Silver Accelerator HR Race Series" engine packages are the best compromise for "Power with LOW MAINTENANCE"
