Uniball Upper Control Arms (TTD07+SilveradoUniUCA) by True Travel Dynamics. Quantity: 2 per Pack. OEM Steel. This set of uniball upper control arms was designed to add strength and help correct the geometry when used on lifted GM half ton trucks and SUVs.
True Travel Dynamics use 1'' uniballs to replace the factory ball joints for added articulation. For the inner pivots True Travel Dynamics use 3/4'' heim joints and stainless steel spacers. With these upper arms you also get custom stainless steel tapered misalignment spacers to adapt to the factory spindle.
All the parts on the arms are replaceable or rebuild-able so they will last you a very long time.
