Adjustable front suspension, Honda TRX 420/500/520 (also IRS models)

The set includes stiffer springs (even stiffer than HD springs), upper spring plates and lower spring plates/coil pins for infinitely adjustable spring bias. The large bias adjustment range (approx. 60 mm) allows the same springs to be used for leisure and work use.

Heavy front implements such as snow blowers, flail mowers, plows and buckets often require a stiffer suspension. When towing a forestry trailer, the suspension is also subject to stress and the original springs may not be able to carry a very heavy load.

Suitable for:

• Honda TRX 420/500/520 (also IRS models) ETU (shock tube diameter approx. 39 mm)
  • Compared to the original springs, these are about 33% stiffer

  .

  • Spring load (i.e. once the spring is mounted on the shock absorber, what force must be applied to the shock absorber to cause it to flex)
    • original spring, bias at minimum, load approx. 70 kg
    • original spring, bias at maximum, max. load approx. 100 kg
    • Latvo set, bias 20 mm, max. load approx. 80 kg
    • Latvo set, bias 60 mm, max. load approx. 240 kg

Note: The spring load cannot be used to draw any direct conclusions, e.g. what kind of implement is carried by the front of the ATV, as this is significantly influenced by suspension geometry etc.
