Extruded mill finish or color anodized aluminum. Includes spacer, bolts and washers needed for eliminating fan clutch from fan assembly. Color anodized spacers may be specified by adding -1, -2, or -3 to the end of the part #. Belt driven fans work best when they are 3/4" to 1" from the radiator's surface. Whenever you remove an original equipment fan clutch from your engine, you need to add a spacer to bring your new fan back into the "sweet spot" in the fan shroud opening. Use spacers according to the applications listed for stock engine set-ups. For engine swaps, check the clearances in your engine compartment and select the spacer(s) you need accordingly. Multiple spacers may be used, up to a maximum of 3". NOTE: USING OTHER THAN FLEX-A-LITE SPACERS WILL VOID THE WARRANTY ON ANY FLEX-A-LITE FAN.Pit Stop USA offers Flex-A-Lite 1" GM, Ford Fan Spacer Kit 14548 at low everyday prices.
