Bronco 2021-2026 Ford 4WD HD Upper Ball Joints (2-Upper Ball Joints) by Teraflex

The TeraFlex 3453000 HD Adjustable Upper Ball Joints for Ford Bronco models are heavy-duty replacement ball joints engineered to increase strength, steering precision, and suspension articulation for demanding on-road and off-road use. Designed as a direct-fit upgrade for the factory upper control arms, these ball joints feature a large 30mm metal-on-metal joint, heat-treated chromoly studs, and durable 1045 carbon-steel housings to withstand increased suspension loads from lifted, high-articulation, and aggressively driven Bronco applications.

The 30mm metal-on-metal joint design provides precise suspension movement and steering response while allowing up to 94 degrees of articulation for increased range of motion. Each ball joint is fully greaseable and adjustable for wear directly on the vehicle, allowing servicing without disassembling the joint. Dual helical grease grooves help purge old grease and contaminants as you add fresh grease, promoting consistent lubrication and extended service life.

For protection in demanding environments, a low-profile seal helps keep dirt, water, and debris out while maintaining quiet operation. A zinc-iron coating adds corrosion resistance against mud, road salt, and changing weather conditions. Combining heavy-duty materials, increased articulation, serviceability, and direct-fit installation, the TeraFlex HD Upper Ball Joints provide a durable upgrade for Broncos used for daily driving, trail riding, rock crawling, and other demanding applications.
