Lowering Spindles or Coils, which one to use

  • Description
Which is the better way to lower my truck, with lowering spindles or lowering coils?
We get asked this question a lot so I thought it should be the first one that I answer.
In most cases a lowering spindle does a better job of lowering your truck. When you use a lowering coil you are basically installing a shorter coil spring which means it's going to give a stiffer ride. Now that's not always a bad thing as a shorter coil will collapse less during cornering which will make your truck handle better but a lot of people want to keep a factory ride quality when they lower their truck.
On the other hand, installing a lowering spindle does not affect the ride quality and generally alignment criteria is built into the spindle making it easier to get a wheel alignment within factory specs. The downfall about a lowering spindle is that what you are doing is actually moving the center of the spindle up and sometimes that means that your factoy wheels will no longer work. That is generally only a factor on late model trucks that use larger brakes than some of the older trucks. There are a few of the older models that you need to do some minor trimming on the lower control arm to prevent rubbing on sharp truns and quite often you need to bend the brake lines to allow clearance for the ball joints.
But if you want to lower your truck more than a couple of inches in the front in most cases you will need to use both spindles and coils in order to achieve anything over a couple of inches.
As for the cost, lowering coils nearly always cost less than a set of lowing spindles. But in some cases (especially trucks with front struts) it is less labour to change a set of spindles than it is to install a set of lowering coils. This can make up part or all of the difference in cost unless you are doing the job yourself.
Hopefully that's enough information to help you make up your mind whether to chose lowering spindles or lowering coils.
