The Cognito Alpha Ball Joint is the top-tier upgrade for press-in style Cognito upper control arms, combining the durability of a heavy-duty ball joint with the performance of a uni-ball. With no boot to rip, a greasable design, and the ability to rebuild it on the truck, this joint is built for long-term performance and easy serviceability.

Part Number: 199-91253

Features

• Designed for Cognito press-in style upper control arms
  
• High-angle design for increased suspension travel
  
• Bootless scraper seal prevents contamination without risk of tearing
  
• Greasable with internal grease cavity for long-term lubrication
  
• Alloy steel internals with no plastic liner
  
• Greater pullout strength than standard ball joints
  
• Zinc-plated housing for corrosion resistance
  
• Fully rebuildable without removing control arm
  
• Pre-greased with Lithium Complex Grade 2 grease
  
• Durability and strength ideal for IFS suspension setups

Notes

• This ball joint is NOT to be used as a droop limiter and was never designed to support suspension components hanging from the ball joint during operation. Doing so will void any warranty and is an extreme safety risk.
• Please measure Ball joints before ordering on older kits. This kit will NOT work on Ball Joints that measure at 55mm or 2.2in
