Rare Parts Diamond Series Ball Joint 05-26 Ford F-250/F-350/F-450/F-550 Superduty 4WD
Description
Restore steering and suspension performance on your Ford Superduty with the Rare Parts 11901 Diamond Series Ball Joint. Designed specifically for the front track bar, this heavy-duty replacement ball joint is engineered to restore proper handling and OE alignment while providing the durability needed for demanding truck applications.
The Diamond Series features a 34mm full ball stud and steel-on-steel internal components for strength and long-term durability. Heat-treated components help withstand the loads experienced by heavy-duty Superduty trucks, while the sealed dust boot helps protect the joint from dirt and other contaminants.
Built for Long-Term Service
Unlike sealed-for-life ball joints, this Ball Joint features a greaseable housing with a 90-degree grease fitting, making routine lubrication easier. Regular maintenance can help extend component life and keep the joint operating smoothly.
Each ball joint is inspected and tested in-house by Rare Parts before leaving the facility. The 11901 is also a 0.006-inch oversize Diamond Series design, providing a precise press-in fit for applicable applications.

How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.
