Frequently Asked Questions
How do I confirm the correct adjustable spring kit?
Match the exact vehicle, chassis, drivetrain, body style, factory damper or air-suspension setup, axle configuration, and AST part number.
Can ride height be changed after installation?
The supplied adjustment hardware is designed to fine-tune ride height within the stated range. The vehicle must be safely supported and the current AST procedure followed.
Will the vehicle need an alignment?
Yes. Settle and measure the final ride height, then align the vehicle and verify suspension, tire, wheel, and brake-line clearance through full travel.
Does the kit replace the factory dampers?
Not unless the exact listing expressly includes dampers. Adjustable lowering spring kits normally retain the compatible damper arrangement identified for that part number.
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.
