Description:
Coil springs support the weight of the vehicle and react to road irregularities. When parked, the weight of the vehicle and occupants compress the coil springs a certain amount to maintain a predetermined ride height. On the road, when a bump forces a wheel upward, the spring compresses further, allowing the vehicle to remain level and isolating the passengers from the impact. After the bump, the spring forces the wheel downward to maintain road contact,for off road vehicle,the coil springs usually bear higher weight as it got longer working length.
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 coils springs:
1. made with high quality material,all are alloy steel,some imported from Japan,KOBE STEEL.
2. coil springs are made from the finest quality, high tensile, chrome silicon wire available.
3. surface treatment powder coating and can be many colors as you wish.
4. Specifically wound for off-road applications; spring rates, wire diameters and coil lengths have been developed through extensive real world testing on all types of terrain.
