LSM Racing Products Valve Train Components

About LSM Racing Products

LSM Racing Products, a brand of Logan Smith Machine Co Inc, has been crafting precision engine-building tools for the racing industry since 1976. Headquartered in Rocklin, California, LSM has built a reputation over nearly five decades for engineering tools that serious racers and engine builders rely on when accuracy and durability are non-negotiable. Every product in the LSM lineup is proudly made in the USA, a hallmark the brand has maintained throughout its history.

Purpose-Built for Engine Builders and Racers

What sets LSM Racing Products apart is its laser focus on the specialized needs of high-performance engine assembly. Rather than producing general-purpose shop tools, LSM designs each product around a specific, demanding task in the engine-building process. Whether you are building a street performance engine or preparing a dedicated race motor, having the right tool makes all the difference in achieving consistent, reliable results.

One of LSM's most recognized product areas is valve train tooling. Their valve spring compressors are engineered for both on-head and off-head applications, giving engine builders flexibility regardless of how they prefer to work. Paired with their Engine Valve Spring Retainer Keeper Tools, these compressors make installing and removing valve spring retainers and keepers far safer and more efficient than improvised methods. For builders who also need to source quality components, LSM's catalog extends into Engine Valve Springs as well, keeping more of the build process under one trusted name.

LSM also offers valve spring pressure testers designed to work across a wide variety of engine platforms, allowing builders to verify that each spring meets specification before the engine ever gets assembled. This kind of pre-assembly validation is exactly the sort of detail that separates a well-built engine from one that falls short under sustained racing conditions.

Precise valve lash adjustment is another area where LSM shines. Their TQ-100KIT Valve Lash Adjusting Torque Wrench is engineered to take the guesswork out of setting valve lash, combining accuracy with ease of use. Complementing this tool are their Feeler Gauges, which provide the precise clearance measurements needed during valve lash setup and other critical engine assembly steps.

Rounding out LSM's engine-building toolkit is their Engine Connecting Rod Vise, a tool designed to securely hold connecting rods during assembly and inspection. Proper rod handling is essential to avoid damage to precision bearing surfaces, and LSM's rod vise gives builders the stable, damage-free grip they need.

A Legacy of American Craftsmanship

For engine builders who demand tools that perform as hard as the engines they are building, LSM Racing Products represents a reliable, American-made choice. With roots going back to 1976 and a product line that continues to grow around the real-world needs of racers and professionals, LSM remains a trusted name in the engine-building community.
