Product Description:
Spohn Performance Del-Sphere Pivot Joints with Spacers for Adjustable Front Lower A-Arms
Specifications: These Del-Sphere pivot joints can be used to replace spherical rod ends on Spohn Part #741 or other brand 1993-2002 GM F-Body adjustable front lower a-arms that have 3/4"-16 right hand threads. The Del-Sphere pivot joints come complete with spacers, jam nuts, grease fittings and allen wrench. This kit includes a set of four Del-Sphere pivot joints.
Del-Sphere Pivot Joints:
The Spohn Performance Del-Sphere pivot joint solves the shortcomings of the factory rubber and aftermarket polyurethane bushings. The 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. 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. The 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 cups, 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 cups absorb shock and road noise so you get the quiet and smooth ride of a bushing as well as 28 degrees of rotation! The Del-Sphere pivot joints will always ship to you fully assembled, however, they 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.
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 application.
