What's covered

  • Defects in material or workmanship under normal use
  • Repair or replacement of the defective part at SPC's option
  • The original consumer purchaser who bought from an authorized distributor, on the vehicle the part was first installed on

What's not covered

  • Products that were abused, altered or installed incorrectly
  • Use in off-road driving, racing or competition
  • Finish and normal wear and tear
  • Lifetime coverage on parts not installed by a professional technician
  • Labor, time, loss of use and other incidental or consequential costs
  • Claims without proof of purchase
  • Freight charges

How to make a SPC warranty claim

  • Go back to the original place of purchase with the part and your proof of purchase; without proof of purchase the warranty is void.
  • SPC reviews the claim and, if the part appears warrantable, issues a Return Authorization number.
  • Ship the part back freight prepaid with the Return Authorization number; freight is the customer's cost.
  • If you need a replacement before the claim is settled, buy it first; if the original part is found warrantable, SPC credits or refunds the replacement.
