If you’ve encountered the rare CP3 clearance issue where the new shaft won’t rotate a full 360° due to manufacturing variances these pre-machined tappets are your quick and clean fix.
Each set has been precision-machined to reduce height by ~0.5mm, eliminating interference with the shaft. Just swap them in using our CP3 Tappet Tool (required for removal), and you’re back in business. No guesswork, no grinding.
