Part # 719H

BDS Suspension 2011-2019 Chevy 2500HD 2wd/4wd 4.5" No Torsion Bar Drop Suspension System.

Like many of our other IFS suspension systems for the Chevys, 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. In the rear, the system comes with a 2" block and u-bolt setup that levels the vehicle perfectly. For those looking for a little more height in the rear, the existing 3" rear block kits can be substituted in.

BDS Suspension - "No Fine Print Warranty"

BDS stands behind its products and that's evident by their No Fine Print Warranty. This warranty protects the original retail purchaser against breakage, bending, sagging, or any other usage failure. We don't care if you jumped your truck off a cliff, lit it on fire, rolled it down a hill, installed Chevy parts on your Ford, or even if you didn't read the instructions and cross threaded a bolt with too many Ugga Duggas! This "no fine print" lifetime replacement warranty extends to cover all BDS hard parts and includes a lifetime warranty on bushings! Exclusions would be product finish and wearable items as described below. All warranties require the customer to provide a Proof of purchase including Name, product, purchase date and price paid.

No Fine Print Warranty ~ If you are the original purchaser of any BDS product and it breaks, they will give you a new part. Period.


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

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.

BDS Suspension's obligation under all warranties is limited to the repair or replacement, at BDS's option, of the defective material. BDS will cover the cost of ground shipping on warranty items, and a return shipping label if we require the warranty part to be returned to us. Any cost of removal, installation or reinstallation, expedited freight charges, incidental or consequential damages are expressly excluded from these warranties. Proof of purchase is required for all warranty claims.
