SPC Consumer Warranties and Procedures

?

Specialty Products Company warrants its products to be free from defects in material and workmanship under normal use. Warranty categories include limited lifetime, limited one year, limited 90 day, or no warranty items. Individual product warranty information may be attained by opening www.specprod.com and entering the specific part number. Warranty information is also included within our PIES file data.

?

Warranty applies to the original consumer purchase from an authorized distributor and only on the original vehicle on which it was installed. This limited lifetime warranty is in effect only when the product is installed by a professional technician. Any product that has been abused, altered, incorrectly installed or used in competition, racing or off road, is not covered. Product finish is excluded from this warranty as is normal wear and tear.

?

Specialty Products Company shall not be liable for any special, direct, indirect, incidental, or consequential damages that might be claimed as a result of the failure of any part, including, but not limited to claims for delay, loss of profits, use, time or labor.?

?

Specialty Products Company shall not be liable for any damage or injury to persons or property resulting from improper installation or misuse of any part subject to this warranty.

Warranty Procedure

?

Should a product fail to function due to a manufacturer’s defect in material or workmanship, the product must be returned along with the proof of purchase to the original place of purchase for verification and replacement. Failure to provide the original proof of purchase voids this warranty.

?

Parts returned must be determined by Specialty Products to be defective and Specialty Products’ obligations under that warranty are solely limited to repairing or replacing, at its option, any part proven defective.

?

Contact Specialty Products Company regarding a claim. If it appears that the part is warrantable, you will be given a Return Authorization (RA) number and asked to return the part freight pre-paid. If the part is found to be warrantable, it will be repaired or replaced and returned to you.

?

All freight charges are the customer’s responsibility. If a replacement part is needed before the part in question can be returned, you must first purchase the replacement part. Then if the part in question is deemed warrantable, you will be credited / refunded the cost of the replacement part.

?

Specialty Products reserves the right to modify pricing, terms of sale, and product offerings without notice.
