If you already have one of our LSM on the engine valve spring compressors, you can easily use your compressor assembly (Retainer housing, lead screw, head, and adjuster screws) and swap out the beam and base combination to work on other heads and mounting styles. Just remove the nuts from the adjuster screws, slip off the red beam, slip on the new beam and base combination, and put the nuts back on the adjusters. It's that simple.
The SC-150™ Beam and Base combination is for wedge/inline engines with two rockers mounted on a single shaft that need wider centerline spacing such as a Windsor Ford. Please see the complete description of the SC-150™ under Valve Spring Compressors for more details and measurements. This item is only for "half" of a LSM spring compressor; the beam and base only.
If you have an older, "vintage" LSM spring compressor you may want to call the factory to check compatibility.
