Cargo and towing vehicles like trucks need a dependable suspension in order to support their own weight and that of their load. But prior to 1804, automobiles carrying heavy loads did not have a way to prevent their body from dipping under heavy cargo. Nowadays, truck owners are lucky because they can install leaf springs under their vehicle, either on the front or rear. Leaf springs have several functions, and these are not limited to supporting extra weight due to loads. These components, which are thin springs stacked on top of each other, are also responsible for keeping your truck's tires and wheels in contact with the road, preventing too much vibration caused by road irregularities, and maintaining the vehicle's alignment. Whether you have a small or big truck, you should never go without leaf springs. Getting one from Pro Comp might be a good decision, but before making the purchase, let us see if the unit is really capable.
- For the rear
- With rubber bushings
- Four layers of springs
- Lifts up to 2.5 inches
- Has a progressive spring design
- Carries a lifetime Pro Comp limited warranty
We tested this component on a 1997 Volvo FL6 and a 2005 Nissan Titan King Cab, and here is what we have to say:
- The unit looked generally good. The metal used was of good quality, the leaves were stacked properly, and the unit came with pre-installed rubber bushings and steel shims. The unit passed our visual inspection.
- Surprisingly, we were able to have more than 2.5 inches of lift for the two vehicles. We got between four and five inches of lift for each truck. But given that the leaf springs were new, we were prepared to see the vehicles' height settle to 2.5 inches after some time.
- The leaf spring we bought did not come with the U bolts needed for the installation. It also turned out that the needed U bolts must be longer, so we were unable to use the spare ones we had.
- When we finally drove the two trucks, we noticed that the ride was a little springy. It was really uncomfortable, especially when the road had a lot of potholes and bumps. Ride quality was not that good.
This leaf spring is one of the affordable ones in the market. The product does not look that bad, it has a good warranty, and it increases vehicle height to more than what is indicated in the specs. When you install this spring, you might experience a change in ride quality. This is not a bad buy, but you could definitely shop around for something better.
