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.
