ATS Springs offers all-in-one leaf spring kits that include leaf springs, hangers, shackles, and Grade 8 hardware for an easier, faster installation. These kits are designed for pickup trucks, vans, and SUVs, giving you everything needed to refresh or repair your suspension.
Why Complete Kits Matter
When replacing leaf springs, it’s important to inspect:
- Leaf spring hangers for cracks or wear
- Shackles for dry rot or worn bushings
In most cases, axle U-bolts should not be reused because they stretch during the original installation torque. ATS Springs includes replacement U-bolts bent in-house from straight rods to ensure proper fit and safety.
Grade 8 Hardware Included
All complete kits come with Grade 8 bolts, locknuts, and washers, providing superior strength and torque retention for a reliable installation.
Heavy-Duty Options Available
For trucks and vans carrying heavier loads, ATS Springs offers heavy-duty leaf spring kits that improve handling, stability, and weight capacity.
Custom Kits
If you don’t find a kit that fits your vehicle, ATS Springs can custom assemble a complete suspension kit to match your needs. Contact us through “Just Ask Bob” or call 1-888-943-8287 to get the right kit with the correct capacity and components.
Benefits of Complete Kits:
Heavy-duty options for commercial or high-load applications
Faster installation, no need to source individual parts
All components matched for your vehicle
Improved ride quality and suspension performance
Understanding the Components in a Complete Leaf Spring Kit
A complete suspension kit includes several critical components that all work together. Replacing only one worn part can leave other weak points in the system, which is why complete kits are often the smartest solution.
Leaf Springs
Leaf springs are the primary load-carrying component of your suspension. They support vehicle weight, maintain ride height, and help control axle movement.
- Standard leaf springs restore OEM ride height and capacity
- Heavy-duty leaf springs increase load capacity and improve stability
- Worn leaf springs can cause sagging, poor handling, and uneven tire wear
Leaf Spring Hangers
Leaf spring hangers mount the leaf spring directly to the vehicle frame.
- They absorb road stress and suspension movement
- Over time, hangers can crack, rust, or wear at the bushing surfaces
- Replacing worn hangers ensures proper alignment and prevents frame damage
Leaf Spring Shackles
Shackles allow the leaf spring to lengthen and shorten as it flexes under load.
- Worn shackles can cause clunking noises and poor ride quality
- Dry-rotted or loose bushings affect tracking and stability
- New shackles restore proper suspension movement
Leaf Spring Bushings
Bushings isolate vibration and allow controlled movement between suspension components.
- Rubber bushings absorb vibration for daily driving
- Bronze or bi-metal bushings offer increased durability for heavier-duty use
- Worn bushings can cause steering wander and uneven handling
Axle U-Bolts
U-bolts clamp the axle securely to the leaf spring pack.
- U-bolts stretch when torqued and should never be reused
- Reusing old U-bolts can lead to axle shift or failure
- ATS U-bolts are bent in-house from straight rods for exact fit
Grade 8 Hardware
Grade 8 bolts provide the strength needed for suspension applications.
- Higher tensile strength than original rivets
- Better torque retention under heavy loads
- Essential for safe, long-lasting installations
Why Choose a Complete Kit Instead of Individual Parts?
- Ensures all suspension components work together
- Eliminates guesswork when sourcing parts
- Saves time during installation
- Improves safety, ride quality, and longevity
- Ideal for vehicles with age, high mileage, or heavy-use demands
ATS Springs complete kits are built to restore factory performance or increase load capacity, depending on your needs.
