Features:

- The tie rods are 1.5x thicker than OEM for reduced flex and have larger inner ball joints for reduced wear. Testing has shown the BD tie rods can take over double the amount of force than what OEM rods can handle. Greaseable ball joints come with sintered bearings and allow for better load holding and increased life. A better solution compared to the 'band-aide' Tie Rod Sleeves.

- Other upgrade kit designs change the geometry of the steering which can sacrifice safety and drivability for straight-line strength while pulling or racing. This can also create a dangerous "bump steer" where the vehicle becomes uncontrollable on uneven roads. By not altering the steering geometry, the BD upgrade kit saves you from this problem. The total package is an economic upgrade for worn-out steering and will increase the durability, longevity, and dependability of your truck while saving money by preventing catastrophic repairs.

- Whether making necessary repairs or upgrades to your steering setup, or running stock to 2" lift or leveling kits, BD's NEW sway bar end links for 2001-2019 Chevy 2500/3500's are your best option to ensure your steering is tight and on the level! Longer, high-strength through bolt design sway bar end links accommodate larger tie rods and leveling kits. Durable polyurethane bushings are designed in the OEM profile to maintain articulation and durability. Leveling kits and lift kits will pull the swaybar out of position, compromising steering geometry. Additionally upgrading tie rods can also cause swaybar interference issues. BD's durable, longer, high-strength, sway bar end links correct sway bar angles and give you the additional clearance you need for those upgraded tie rods. Tighten up the sway bar assembly on your truck and ensure your truck's control is direct and confidence inspiring while avoiding that front end "clunk" that comes with worn out bushings.
