Del-Sphere Pivot Joint - Narrow Mount - Forged - 3/4"-16 Left Hand Threads
This Del-Sphere™ pivot joint is designed specifically for narrow mount panhard bar and track bar applications. It can be mounted inside of a mounting bracket that is as narrow as 1.5625" i.d. and still reach its full 22º of articulation without the housing contacting the mount!

You can bush down the ball's through hole and utilize spacers on each side of the ball to mount these Del-Sphere™ pivot joints on any application. The Del-Sphere™ pivot joint comes complete with a jam nut and grease fitting.
The suspension bushings on your vehicle have a significant impact on your vehicle's ride, comfort, handling, acceleration, noise, and vibration. When the vehicle leans (rolls), one side of the chassis moves up relative to the axle, and the other side moves down.
The suspension's arms must twist to allow for the axle housing to articulate, this causes the bushings to bind. If this bind becomes excessive, it will raise the wheel rate and produce sudden and uncontrolled changes in handling such as snap oversteer.
The factory minimizes this suspension bind by using compliant rubber bushings. These soft bushings help accommodate the necessary motion of the suspension's arms during articulation. However, the rubber bushings do not provide much in the way of forward and aft support which can cause wheel hop during hard acceleration and braking.
It is common to replace the stock rubber bushings with polyurethane bushings to resolve the shortcomings of the factory's soft rubber bushings. Polyurethane bushings eliminate wheel hop, reduce axle deflection, and improve straight line traction. However, the downside of polyurethane bushings is they prevent the necessary movement of the suspension's arms during body roll, which in turn produces significant binding in the suspension when the vehicle is articulating.
The polyurethane bushings also place high stresses on the suspension arm mounts on the vehicle. Polyurethane bushed suspension arms do not allow for rotation of the arm during articulation because of the stiffness of the bushings.
Del-Sphere™ Pivot Joint:
The Spohn Performance Del-Sphere™ pivot joint solves the shortcomings of the factory rubber and aftermarket polyurethane bushings. Our Del-Sphere™ pivot joint
incorporates a spherical ball which is surrounded by Delrin® bushing cups.
Think of the Del-Sphere™ pivot joint as a Delrin® bushed spherical rod end. The Delrin® bushing cups absorb shock and road noise so you get the quiet and smooth ride of a bushing as well as 22° of rotation! Designed and manufactured exclusively by Spohn Performance, we have taken street suspension performance to the next level.
Our Del-Sphere™ pivot joint features a one piece forged and heat treated 4130 chrome moly housing, a heat treated and hard chrome plated 52100 bearing steel spherical ball, Delrin® bushing cups, heat treated retainer washers and snap ring, an external grease fitting, and a beautiful silver zinc plated housing finish.
We doubt you'll ever need to replace the Delrin® bushing cups, but they certainly can be. Unlike a spherical rod end, the Del-Sphere™ pivot joint is 100% rebuildable.
