19203 Ski Doo EverLaster Carbide Blade-Z 1993-1996 Steel Bridged skis.  These 1/4" wide blades provide 5/8"-3/4" penetration (when new), with 6" of carbide.  With this added penetration there will be an improvement in traction/handling, so ski spring adjustment (or more) may be necessary to obtain best results.
