Make your own

Or, make your own performance bushings per Nissan Competition book:

  • 16273.jpg
    • I went to a local platics place and bought a piece of

Aftermarket

Or, get stiff aftermarket bushings:


I got in touch with MADDAT.COM and they knew exactly what I was looking for. They had it in stock from Super Pro (yes they're polyurethane), sent them right out, and I received them 8 days later here in Arizona, USA. Tamra from the sales department was easy to work with and very helpful. I would recommend these guys to anyone who needs parts for their 1200. Front spring eye bushing on rear leaf spring

Polyurethane bushings out of Mexico: Parbo
