Default Progressive Rate Springs

I have got progressive rate king springs, and was just wondering which way around they go? Does the part where all the coils are bunched go at the bottom or top? cheers.

i thought it was the top but it's probably best to call the supplier to be sure to be sure

I don't think it matters as the spring will load up either way. There should be markings on the spring, eg, left and right also the top of the coil should have this way up, or top.

I think the bunched coils should go at the top... Basically all King Springs are progressive rate now days, and thats what mine are so i'll check tomorrow.

the tighter coils go at the bottom... hence why its called progressive rate lol, the more load you put onto the spring, the harder the spring gets as the coils get closer together

If the springs are the wrong way around it completely defeats the purpose I think.

Basicly the advantage of progressive rate is that the coils actually touch during cornering, effectively reducing the number of coils in the spring and therefore increasing the spring rate. High spring rate when you need it, standard spring rate when you dont need it

bunched coils go to the top, with more load the spring stiffens, sorta like monroe sensatrac shocks, soft in the earlly stages and stiffer with more load

Either way, the coils will still bunch up when you put load on them. Whether they are at the top or bottom the coils that are softer will compress first.

With sensortrac shocks, the heavier valving is at both ends. When the suspension travels further than normal, in harder driving circumstances the shock firms up. It's not a good idea to have sensortracs on a lowered vehicle as it is stiffer when driving sedately but when you drive hard the shock moves into the standard valving area and actually handles worse.
