Wearable Parts | Limited Lifetime Warranty
BDS NX2 Series Shocks and BDS/Fox Performance Series Shocks: Shock oil seals are not covered by this Limited Lifetime Warranty because they are subject to wear over time and use. At BDS's discretion, leaking shock seals less than 2 years from date of purchase, free from contamination, damage, or abnormal seal wear due to misuse can be considered for repair or replacement under warranty. A shock absorber is a wear item and over time will experience diminished damping resistance due to normal component wear. This is not a defect in material or workmanship and is therefore not warrantable. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion.
Fox Proprietary Shocks and Coil Overs: Fox Proprietary parts are covered by their warranty and are not included in the BDS Warranty. BDS may offer to assist with the warranty of defective product, at our discretion. Other warranty concerns should be handled through the Fox Service program. Leaking shock seals less than 1 year from date of purchase, free from contamination, damage, or abnormal seal wear due to misuse can be considered for Warranty. FOX service information can be found here: https://www.ridefox.com/service.php?m=truck
Ball Joints and Tie Rod Ends: These items are subject to normal wear over time. However, Ball Joints and Tie Rod ends less than 3 years from the date of purchase, that have been properly greased, maintained, and do not show signs of abnormal use can be considered for warranty.
