Spohn DS34TB - Manual

Part# DS34TB-X Track Bar 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.
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. To disassemble the
joint remove the snap ring using a snap ring pliers. Re-assembly will required the use of a press (or
vise) to push the bushings in hard enough to be able to re-install the snap ring.
Dimensions: This track bar Del-Sphere™ assembly must be mounted inside of a minimum 1-9/16”
i.d. mounting bracket to insure the housing does not contact the bracket at full rotation. The joint will
provide for 22° of articulation. The housing has a 2.05” outside diameter and is 1.20” wide. The ball is
0.875” wide and has a 0.75” through hole. The thread length is 2.50” and the size is 3/4”-16. The
overall length of the joint end to end is 4.92”. The length from the center of the ball hole to the start
of the threads is 1.50”. The length from the center of the ball hole to the end of the threads is 4.0”.
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
suspension performance to the next level. This Del-Sphere™ pivot joint features a one piece forged
and heat treated 4130 chrome moly housing, a heat treated and hard chrome plated chrome moly
spherical ball, Delrin® bushing races, heat treated retainer washer and snap 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 22° 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.
