Leaf Springs: Suspension Leaf Springs, Parabolic and Trailer Leaf Spring Options

Leaf springs are the original suspension technology engineered for load capacity and durability above all else. Found on trucks, trailers, and commercial vehicles worldwide, they carry vehicle payload through a stacked steel construction that keeps working where other spring setups fail.

At CBT Auto Parts, we stock suspension leaf springs across parabolic leaf spring options, trailer leaf spring assemblies, and leaf spring kits, part of our complete Suspension & Steering Parts range. Silverado, Jeep YJ, and commercial trailer fitments are covered; every spring is matched for exact load rating, leaf spring bushes are stocked alongside OEM and aftermarket options are available, and fast shipping gets your vehicle back to work.

FAQs

1. How do I confirm which leaf spring specification is correct for my vehicle?

Each listing includes load rating, free length, and fitment data by make, model, and year. Confirming the load rating against the vehicle's actual payload requirement before ordering is essential.

2. What is the difference between a parabolic leaf spring and a standard multi-leaf pack?

A parabolic leaf spring uses fewer tapered blades for a lighter assembly and better ride quality. A multi-leaf pack uses more uniform blades for maximum load capacity. Both serve the same function but suit different applications and load requirements.

3. Should leaf spring bushings always be replaced alongside the spring?

Yes. Installing new leaf springs on worn leaf spring bushes introduces movement into the mount immediately and accelerates fatigue of the new assembly. Both should always be replaced in the same repair.

4. Are trailer leaf spring bushings the same as vehicle leaf spring bushings?

Not necessarily. Trailer spring eyes are often a different internal diameter from vehicle spring eyes. Always match the bushing to the correct spring eye diameter, either by confirmed vehicle fitment or by size for non-standard applications.

5. Are polyurethane solid leaf spring bushings worth the upgrade over rubber?

For off-road and heavy-duty applications, polyurethane solid leaf spring bushings outlast standard rubber significantly. For regular on-road use, OEM rubber leaf spring bushes provide adequate performance and a quieter ride.
