IRS Pivot Bolt For Rear Trailing Arm

This is the special pivot bolt that connects the rear IRS trailing arm to the frame horn bracket.  The arm pivots on this bolt as the suspension cycles.  It is common for this bolt to become stripped or even broken if it loosens up while driving.  Make sure when installing it that you use a thread locking compound and peen the bracket into the bolt to prevcent it from coming loose. One bolt is required per side, as well as two washers.
