Spohn 2.50" O.D. x 0.325" Wall Weld On DOM (Del-Sphere Pivot Joint)

The width of the housing is 1.50", the diameter of the housing is 2.50", the width of the spherical ball is 1.3425" and has a 0.75" through hole. The housing has a 0.325" wall thickness and is CNC machined from 1020 mild steel and may be MIG or TIG welded.

You can bush down the 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 grease fitting and Allen wrench.

These extreme duty weld on Del-Sphere pivot joints are perfect for off-road 4x4 buggy, truck, Jeep or rock crawler projects! They will work equally as well on performance vehicle handling applications.

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) in a turn, 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 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 body roll. 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 cornering.

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 cornering because of the stiffness of the bushings.

Del-Sphere Pivot Joints: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.

This combination allows the bar to articulate like a spherical rod end (28? of available rotation) during cornering but the spherical ball does not allow the bushing to deflect. Therefore the bar remains completely bind free like a spherical rod end during cornering for predictable traction in the corners.

Think of the Del-Sphere pivot joint as a Delrin bushed spherical rod end. After over a year of R&D testing here at Spohn Performance on a streetable spherical joint the Del-Sphere pivot joint is the final result. Designed and manufactured exclusively by Spohn Performance, we have taken street suspension performance to the next level.

This Del-Sphere pivot joint features a CNC machined 1020 mild steel housing, a heat treated and hard chrome plated 52100 bearing steel spherical ball, Delrin bushing cups, heat treated retainer washer and snap ring, heat treated and chrome plated chrome moly threaded adjuster ring, and an external grease fitting.

The Delrin bushing cups absorb shock and road noise so you get the quiet and smooth ride of a bushing as well as 28? of rotation! Our Del-Sphere pivot joints will always ship to you fully assembled, however, we also offer an optional adjusting tool that will allow you to do two things.

First, you can disassemble the Del-Sphere pivot joint for cleaning, inspection, etc. Second, you can adjust the amount of friction on the spherical ball. Do you want a very low friction pivot joint or a very tight pivot joint? It's up to you, the amount of tension can be easily adjusted by using our optional adjustment tool to tighten or loosen the end retainer ring.

What that also means is if over time and miles the tolerances open up you can simply re-adjust the retainer ring and have your pivot joint as tight as it was the day it was brand new. 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.

Dimension Specifications: These Del-Sphere pivot joints are for custom built applications and are a weld on end, so welding is required.
