Del-Sphere Pivot Joint Instructions & Notes

The Del-Sphere pivot joints are slightly greased for assembly purposes. The bushings inside of

the del-sphere pivot joints are made of Delrin, which is self-lubricating. We do not recommend
greasing the pivot joint any further than as it is supplied as further grease will only attract and

retain dirt and grit. The pivot joints are equipped with grease fittings simply because we know
certain customers would want/request them no matter what we say. You’ll also note we have a

second tapped grease fitting hole with a threaded plug installed so you can change the
position of the grease fitting on the pivot end for better access if need be depending on your

mounting set-up on the vehicle.

Our Del-Sphere pivot joints are 100% rebuildable. We doubt you will ever need to rebuild
them, but they certainly can be. The delrin bushings should last the life of your vehicle. What

you may find is after you have a lot of miles on the pivot joints the tolerances may slightly
open. It is for this reason that we made the pivot joints adjustable. By tightening the threaded

end retainer you can take up any slack and make the joint as tight as it was when new, it’s
that simple. This also allows you to vary the torque load applied to the pivot ball. If you want a

very low friction joint you can loosen the threaded end retainer, etc. When making
adjustments to the threaded end retainer you will need to loosen the set screw with an allen

wrench. When making your adjustment align one of the threaded retainer end’s slots with the
set screw and re-tighten the set screw, this locks the threaded end retainer’s position in to

place and keeps it locked to your setting. Use our Part# DS34-W adjusting tool for easy
adjustments.

What is a Del-Sphere pivot joint? Think of the Del-Sphere pivot joint as a Delrin bushed

spherical rod end. 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 chrome moly housing, a heat treated and chrome plated
chrome moly spherical ball, Delrin bushing races, heat treated retainer washer and snap ring,

heat treated and chrome plated chrome moly threaded adjuster ring, an external grease fitting
and a beautiful silver zinc plated housing finish. The delrin bushing races absorb shock and

road noise so you get the quiet and smooth ride of a bushing as well as 28 degrees of
rotation!


What is Delrin, and why did you choose to use it? Delrin is an acetal homopolymer made

by DuPont. It is characterized as having an excellent combination of physical properties that
make it suitable for numerous applications. With extremely low moisture absorption and a low

coefficient of friction (self-lubricating), Delrin is uniquely tailored for wear applications in high
humidity or moisture environments. Delrin will maintain constant physical properties under

high moisture conditions and out-perform nylon or polyurethane under these conditions. Delrin
has a 10,000 psi tensile strength and a 120 Rockwell Hardness rating making it ideal for our

Del-Sphere pivot joint application.
