Z1 Motorsports Adjustable Tension Rods for '89 - '94 Nissan 240SX models add positive caster adjust-ability to help improve alignment for handling or to get your Z back to OE specs after lowering or damage to the forward suspension mounting points.
With over a year in development and testing, Z1 Motorsports is now proud to offer a fully adjustable and customize-able Tension Rod solution for the S13 chassis.  Thorough examination of the factory suspension as a system and on a component basis led to our approach.  After testing the many options available on the market, finding common shortcomings, "issues" and failure points, we decided that a no compromise approach was the solution.  We set forth an extensive list of design goals and product requirements; we believe it has led us to nothing short of the best part available for this application.

Inspected, assembled, re-inspected and packaged in house by Z1's trained staff, the adjustable tension rods arrive ready to install on your vehicle right out of the box.  A professional alignment is strongly recommended after the installation of the arms.

Standard Tension Rod Components:

  • Body - Machined from solid, billet 6061 Aluminum and hard anodized black; the fluid design is not only aesthetically pleasing its form is completely functional.  Clearance will not be any issue through the full range of suspension travel.  Why aluminum? Weight was at the top of our list for requirements, to add adjustment to the factory arm and even match the weight without being heavier was a steep challenge.
  • Adjuster - Machined from Stainless Steel, the adjuster is a critical part of the arm for both safety as well as adjust-ability.  Careful consideration was taken to ensure maximum adjust-ability without compromising safety or increasing the arms' overall weight unnecessarily.  Stainless was used for long life while offering a great strength in a compact size.  We even had your alignment tech in mind when designing these parts, featuring a double adjuster alignment changes are quick and easy with a turn of this jewel.  Even selecting the size of the part features like the adjuster hex and the jam nut size was important; it can be tight working in this area of multilink suspension so keeping lock nuts a reasonable size and centralized was important to us.  Even if you don't have a 27mm and 30mm wrench to tighten these up, you should be able to succeed with a reasonable sized crescent wrench.
  • Jam Nuts - Not readily available before production in our desired size custom LH and RH thread jam nuts were spec'd, and like the rest of these components not only were their outer dimensions spec'd even the thread class was specified.  To continue with the corrosion resistance these fasteners are also produced in Stainless Steel.
