SUPERTECH BUCKET TYPE CAM FOLLOWERS AND MINI SHIM KIT
This kit is designed to fit the Subaru Imprezas that have the AVCS cylinder heads but can also be used in the V5 onwards cylinder heads if the valve spring retainers are the later non shim type
The kit contains 16 Supertech Cam Followers and 16 "mini" shims (sizes are to be calculated)
These Bucket lifters are designed using the latest CATIA CAD software and Finite Element Analysis (FEA) for the high demanding conditions of endurance racing, road racing or drag racing.
They cannot be compared in any sense with the cheaper, extruded or factory supplied lifters due to the superior materials, coatings and superb manufacturing that is only found at a Formula 1 level.
Some features of the Supertech lifters are:
- Aerospace certified Chrome-Molybdenum-Vanadium alloy from Austria. This is a much stronger material than the alloys used in factory extruded lifters.
- Completely CNC machined from heat treated billet provides only the necessary and calculated thickness of the walls with very special shapes, providing better rigidity with an important reduction in weight.
- The lifters are fully Nitrided and polished to harden the surface to about 60Rc for low wear. Higher cam lifts and rpms will submit conventional lifters to an important wear.
- Surface is carefully finished by grinding it to a much lower surface roughness for lower friction with the cams, cylinder head bore, providing longer durability.
This is why Supertech lifters are performance lifters, and the answer for your racing engines and will work well with our Cosworth camshafts too.
