All the benefits of our PC-100™, but with slanted/convertible handle options that are better for space constraint situations. LSM Racing Products has the most versatile spring tester available!

The LSM PC-100SLC™ can be used in either a straight (conventional) handle position or a slanted configuration. Just remove the jam nut on top of the frame and screw the handle in its place. 

The PC-100SLC™ includes two handles: 4" and 5.625" that can be used separately or screwed together for better leverage. It has the complete adjustability of the PC-100™ plus the benefit of multiple handle configurations for engine compartment constraints. You can also purchase additional PC handles for added length. 

If in doubt between the two tool options, we recommend the future-proof option of the PC-100SLC™. Plus, when using both handles together you have 9.625" vs. 8.0" to pull on. 

When choosing the correct gauge PSI option for your seat pressure, keep in mind that you never want to exceed the gauge limit as it can damage the gauge. Per the specifications of the gauge manufacturer, the most accurate testing location is the middle one third range on the gauge. For example, if your seat pressure is between 250 and 350, you will want the 600 PSI option.
