Description:
The front suspension spring showed are used in truck, it carries the weight and sits the truck at the optimum ride height to provide maximum suspension performance, and it own multiiple rate.
Too much spring rate and the truck will sit at the top of the shock's compression stroke meanwhile not enough will sit too far into the shock. The multiple rates are achieved by the distance between the coil winds, the narrower the distance the less the rate . This means it takes more energy to compress the spring the higher the rate. The multiple rate provides a mechanism to offer a lighter spring rate at the top of the compression and increase the rate progressively through full compression. This is a ride quality initiative for unloaded, low shaft speed compression function. As you can see from the photo, the coil is wound tighter at the bottom of the spring. In a linear rate coil spring, all of the gaps between the coil winds are identical, which makes for a linear rate through full compression of the spring.
features of XULONG suspension springs:
1. made with high quality material,all are alloy steel,some imported from Japan,KOBE STEEL.
2. our suspension springs own multiple spring rate.
3. surface treatment powder coating and can be many colors as you wish.
notes: our suspension springs are produced as per your drawings or samples,plz feel free to contact us!
