Ride Height Drop
Engineered to provide a level, aggressive street stance.
| Position | Ride Height Drop |
|---|---|
| Front | 1.5 inches |
| Rear | 3.0 inches |
The larger rear drop helps eliminate the factory rake common on GMT360 SUVs, giving the vehicle a lower, more performance-oriented appearance.
Premium 55CrSi Chromium-Silicon Spring Steel
Each spring is manufactured from 55CrSi chromium-silicon spring steel, a premium alloy widely used in performance suspension applications for its strength and fatigue resistance.
Construction features include:
- 55CrSi chromium-silicon spring steel
- Cold-wound manufacturing
- Tensile strength of approximately 1,500-1,600 MPa
- High fatigue resistance
- Structural durability for long-term use
- Performance-engineered spring design
The combination of premium materials and precision manufacturing helps maintain consistent ride height while resisting premature spring fatigue.
Improve Handling and Vehicle Control
Lowering the suspension improves more than just appearance.
Performance benefits include:
- Lower center of gravity
- Reduced body roll
- Improved steering response
- Better cornering stability
- Reduced front wheel gap
- More planted highway handling
- Improved weight transfer
- Sportier overall appearance
The result is a Trailblazer or Envoy that feels more controlled and responsive during everyday driving.
Direct Replacement Design
These springs are engineered as direct replacements for the factory coil springs.
Compatible with:
- Factory suspension mounting points
- OEM replacement shocks
- Most aftermarket performance shocks
No cutting or welding is required when installed correctly.
Durable Street Performance
Designed for daily-driven SUVs, the maXpeedingrods lowering springs provide:
- Long-term structural durability
- Improved suspension response
- Comfortable street manners
- Reliable performance under repeated use
- Excellent resistance to spring fatigue
The cold-wound construction helps preserve spring consistency throughout years of driving.
Installation Information
Estimated Installation Time
3-5 hours
Professional installation is highly recommended.
Following installation:
- Perform a professional wheel alignment.
- Inspect factory shocks, upper mounts, and control arm bushings.
- Verify wheel and tire clearance.
- Recheck suspension hardware after the initial break-in period.
Because the rear suspension is lowered by approximately three inches, vehicles equipped with oversized wheels or tires should be checked for clearance after installation.
