K-Liners
Our leadership in developing new, cost effective ways to repair worn valve guides led to the development of the Bronze Bullet Interrupted Spiral Guide-Liner over thirty years ago.
Today the Guide-Liner is one of the most popular repair alternatives, approved by Ford GM, Caterpillar, Cummins, amongst other OEMs for use in rebuilding their engines.
