Frequently Asked Questions
How do I confirm these springs fit my vehicle?
Match the exact year, make, model, chassis, drivetrain, body style, engine, factory suspension, axle-load notes, and AST part number.
Will I need an alignment after installing lowering springs?
Yes. Measure ride height after the springs settle, then perform a complete alignment and verify tire, wheel, brake-line, and suspension clearance.
Can these springs be used with factory dampers?
Only when the exact AST application permits it. Check damper condition, available travel, bump-stop requirements, and every product-specific suspension note.
Is the advertised drop exact on every vehicle?
The stated drop is a target for the listed configuration. Actual ride height can vary with equipment, vehicle weight, spring isolators, damper condition, and prior suspension changes.
Installation Instructions
- Confirm the exact AST part number, complete application or dimensional specification, included components, and current instructions before disassembly.
- Support the vehicle at approved points and record the original ride height, alignment, suspension orientation, and adjustment settings.
- Install components in the specified position and sequence using correct spring-compression, torque, preload, ride-height, and damper setup procedures.
- Verify full suspension and steering travel, tire and wheel clearance, brake-line routing, fastener torque, and damper operation.
- Settle the suspension, measure final ride height, complete a professional alignment, and recheck the installation after the initial driving cycles.
