Description
Like many of BDS's other IFS suspension systems for the GM trucks, this 4.5" system is packed with the same features and benefits of the current 6.5" kit but designed for a lower lift height for those looking for a more modest setup. Like the 6.5" system, the 4.5" includes one piece crossmembers, differential drop brackets, ductile cast iron steering knuckles and bolt-on no torsion bar drop brackets that keep the torsion bars in the factory location at the frame. Also included are stainless steel front brake lines, extended sway bar links and differential skid plates. The front replacement steel splash guard with the BDS logo finishes out the front of the clean, high clearance design. Rounding out the front of this kit are FOX 2.0 performance series IFP shocks or BDS NX2 Nitro shocks. In the rear, the system comes with a block and u-bolt setup that levels the vehicle perfectly. For those looking for a little more height in the rear, 3 and 4 inch block options are available to help you fine tune the amount of rake you want in the rear of the truck. All kits come finished in a durable textured black powdercoat and sent with all hardware packs to complete the install along with step-by-step installation instructions. Shock Options: NX2 Nitro Series Shocks - BDS NX2 series gas shocks offer impressive performance on and offroad. They use a nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving for lightning-fast dampening and superior control. FOX 2.0 Performance Series Shocks - Fox 2.0 performance series shocks have been tuned and tested by both FOX and BDS Suspension to maximize performance specific to each application and every BDS Suspension system. The Internal Floating Piston (IFP) shock design is based on proven Fox Racing Shocks race products but re-designed to maximize the ride quality, handling, and control of your BDS-equipped truck, whether on or off the road. Recoil Traction Bar Kit Increase your traction and stability without limiting your movement with this BDS Recoil Traction Bar Kit. When your truck is in high torque situations, you need extra help absorbing shocks or vibrations through your system. Install these traction bars to smooth out your ride, increase stability while off-roading, and increase durability throughout your truck. Single NX2 Nitro Steering Stabilizer Are you worried about your steering control? NX2 Nitro Steering Stabilizer is designed to be a high-end performance shock at an affordable price. Built with a durable metallic finish, a large fluon-banded piston, and self-lubricating seals this stabilizer is tough enough to last but tuned with vehicle-specific valving to give you amazing control. Built with both the morning commute and some light off-roading in mind, keep stress out of your steer and install one of these today!

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.
