2" UCA KIT W/ DL 2.5 & 2.25 07-13 GM C/K1500 P/U & 14-18 C/K1500 P/U W/ OE FORG STL UCA.

Arms eliminate upper ball join w/super strong 1 ID stainless American uniball. Additional caster is built into arms for greater align ability to help with problematic leveling kit alignments. Allows for increased wheel travel when used w/Dirt Logic 2.5 coilover shocks. Chromoly tubing reduces flex found in stock arms for more positive road feel. 4340 heat treated uniball pin fits into factory ball join taper without modification to the spindle for easy return to stock feature. Arms are direct replacements for factory arms on suspensions that require additional strength and align ability.
