SBI takes tremendous pride in serving as Exclusive Master Distributor for K-Line Bronze Bullet® brand valve guide liners and guide liner tooling.

For nearly a quarter-century, K-Line Bronze Bullet® brand valve guide liners have consistently maintained their top spot around the world as the industry standard in engine rebuilding based on quality of material and manufacture, efficiency of installation, and durability.

Commitment to designing and testing its product to meet the ever-changing needs of the engine rebuilding market defines K-Line's approach to development and manufacture of their valve guide liners and guide-liner tooling. Their certified manufacturing processes guarantee level-best quality for each and every application.

K-Line originally developed bronze valve guide liners for the trucking industry, where fleet engine dependability is a must. Freight carriers expect to get hundreds of thousands of miles per engine between rebuilds; furthermore, a big rig's time spent off the road and in the shop is an expense that ultimately eats into carriers' bottom line. As a result, fleet engines are rebuilt many times over with quick turnaround to minimize this expense.

K-Line's Bronze Bullet® brand valve guide liners are made of spring-tempered phosphor bronze, which is an anti-seizing, anti-wear, high strength-to-weight-ratio material. It is more dense than cast iron, has a higher rate of thermal conductivity, a lower coefficient of friction and insures higher lubrication retention due to the interrupted spiral feature of the product engraved on to the inside of the liner.

The inner design of Bronze Bullet® brand valve guide liners—patented by K-Line—allows for lubrication to be held in the guide, enhancing wear characteristics and reducing the possibility of excessive oil blow back. This patented design feature provides superior installation and fitting characteristics.
