These new FSLI4 calipers use the latest innovations to the Superlite family of calipers.
Commonly used on three or four corners of dirt late models (Dynalite use on the right front corner is also common), asphalt late models, and the rear of big-block style modifieds, these calipers have been redesigned with internal fluid ports that eliminate the external fluid cross-over tubes, along with any potential problems that could arise from a damaged tube.
The transfer tube has been replaced with two additional bleed screw assemblies which allow this group of right and left hand oriented differential piston bore calipers to be mounted in either a leading or trailing position.
With assembled weights just at 4.4lbs, the caliper body design in itself is a product of computer generated solid modeling and stress analysis technology.
These are popular calipers for all types sustained hard braking on dirt and asphalt ovals and a wide range of off-road, rally and road course applications.
