Kibblewhite's bronze valve guides and RED Viton seals are the best on the market, delivering rock-solid durability and preventing oil burning and loss of power. The one piece design eliminates potential failure points of multi-piece guides. Precision CNC machining ensures perfect fitment while the Viton seals can handle extreme heat without deteriorating.
