About BDS Suspension

BDS Suspension was started in 1996 by a business group who felt it was past time to create a suspension company that truly had the best interest of the off road consumer as its' foundation. With over 45 combined years experience with other major suspension companies, both buying and selling, the individuals that would make up the BDS name were frustrated by the lack of quality and the unwillingness to make things right by these 4x4 companies. So, they set out to create a suspension company that would be the best and made a list of the things they felt were not right and made it their mission to correct them.

One of the most important of these wrongs they were looking to right were that of other companies warranties. Too often, the standard protocol was that a broken or damaged part from another manufacturer was denied warranty because of abuse or neglect. For BDS, its simple, if it breaks, they'll replace it, and that is the motto in which they have based their entire warranty off of. So, they welcome you, try and break it, if you do, they'll replace it and probably try to determine a way to increase the rigidity of the product to ensure it never happens again.

BDS LIFT KITS

While most people whom have heard of BDS Suspension automatically think of "lift kits," that ony touches on the wide variety of suspension and steering related products that BDS offers. BDS understands that not everyone is after a complete lift kit, but still after the quality BDS products bring to the table. Some of our most popular products from BDS are replacement adjustable track bars and dual steering stabilizer kits that in many instances can be installed on a completely stock truck, or one that's leveled or lifted. Other popular "non lift kit" parts are leveling kits that include upgraded shocks, progressive rate coil springs, heavy duty control or radius arms, and even leaf springs.
