Replace your Jeep's factory ball joints with Synergy MFG's Dana 30/44 Heavy Duty Ball Joint Set. These ball joints employ a metal on metal design to improve durability and performance.

Features:

  • Compatible with all aftermarket axle shafts (including RCV) with no modifications needed
  • Fully Greasable metal on metal design for prolonged life
  • Ball Joint bearing surface area is considerably larger than stock due to elimination of the inner nylon liner for a longer lasting joint
  • Ball joint housing is manufactured from sintered graphite, bronze, and 1045 steel for a strong, smooth, bearing surface
  • Ball joint stud is manufactured from induction heat treated 4140 steel for maximum strength and smooth operation
  • Ball joint dust boot is made from wear/tear resistant black nitro-butile rubber (NBR)
  • 12 Month Unlimited-Warranty (see warranty information)

Notes:

  • Metal on metal ball joints require a small break-in period of typically 100-500 miles to fully seat the bearing surfaces.

Beats rope plugs every time

Used plenty of plug kits. This screw-in type is faster, cleaner, and no arm workout. Large size seals a real nail hole tight. Trunk ready.
