Datsun 1200 used the tried and true leaf spring (blade) rear suspension, which was common among most cars - including american cars - in the early 1970s.
Contents |
Overview
Sedan and Coupe use the same leaf-pack.
VB110 Wagon came with heavy-duty spring pack.
The B120 1200 Truck came with standard or optional (heavy-duty) rear leaf springs. Standard was a 4-leaf pack, while optional was a 5-leaf pack with a stiffer spring rate.

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

Maddat Leafs
LS1200 Lowered Rear Springs, Heavy duty leaf springs, king spring, reverse-eye lowered.
They are a combination lowering spring and traction spring:
- Flipped half-leaf to control torque windup
- Reversed eyes for lowering
- Reset leafs for lowering
- Compound reset for anti-tramp qualities
120Y Springs
120Y has same length spring, but locates the differential in a different spot. Not Interchangeable.
