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

1. Confirm the exact AST part number, complete application or dimensional specification, included components, and current instructions before disassembly.
2. Support the vehicle at approved points and record the original ride height, alignment, suspension orientation, and adjustment settings.
3. Install components in the specified position and sequence using correct spring-compression, torque, preload, ride-height, and damper setup procedures.
4. Verify full suspension and steering travel, tire and wheel clearance, brake-line routing, fastener torque, and damper operation.
5. Settle the suspension, measure final ride height, complete a professional alignment, and recheck the installation after the initial driving cycles.
