Manufacturer's Warranty — Torque Solution

Torque Solution states a Limited Lifetime Warranty on its manufactured billet aluminum and polyurethane parts — engine, transmission and differential mounts, shifter and suspension bushings, blow off valve adapters, exhaust hangers, flanges and fittings. Its electronic parts (Fast Response IAT sensors and PNP speed-density adapter harnesses) carry a 1-year warranty instead. Wear and consumable items — turbo blankets, intake gaskets, exhaust wrap and heat tape — are sold without a stated warranty term. Coverage applies to the original purchaser against manufacturing defects; check the individual product listing for the term that applies to that part.

Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by Torque Solution. Contact us if you need help with a warranty claim.
