Belltech PRO COIL SPRING SET 07+ GM SUV 4inch WITH AUTORIDE - 34324

The Belltech Pro Coil Spring Set (Part #34324) is a purpose-built rear lowering spring kit designed for 2007-and-later GM full-size SUVs equipped with factory AutoRide or Magnetic Ride suspension. Engineered to deliver a lower, more aggressive stance without sacrificing ride comfort, this set gives you two distinct drop heights in a single purchase — making it one of the most versatile rear lowering solutions available for trucks and SUVs in its class. Whether you're building a slammed show truck or simply want to eliminate that factory rake and improve handling, Belltech part 34324 is designed with the serious GM SUV owner in mind.

Key Features & Benefits

• Two Lowering Height Options in One Kit: The 34324 ships with both springs and spacers packaged as a set, giving you a 3" or 4" rear drop depending on your preference — all without buying a second kit.
• Cold-Wound Chromium Alloy Steel Construction: Each coil spring is manufactured from cold-wound chromium alloy steel, then shot peened and powder coated to exact specifications, ensuring long-term durability and consistent spring rates over the life of the product.
• Lower Center of Gravity & Reduced Body Roll: Dropping the rear of your GM SUV tightens up cornering response and reduces the side-to-side body sway that stock-height full-size trucks are known for.
• High-Quality Injection-Molded Spacers: Belltech includes precision injection-molded spacers that allow you to fine-tune your drop height without additional parts or machining.
• OEM-Quality Bump Stops Included: Replacement bump stops are packaged with the springs to maintain proper suspension travel limits and protect your components after lowering.
• Designed for AutoRide / Mag Ride Vehicles: Part #34324 is specifically validated for GM trucks running factory electronic suspension (AutoRide or Magnetic Ride shocks) — no electronic conflicts or sensor issues for correctly matched vehicles.
• Compatible with Additional Lowering Components: These springs can be combined with front lowering spindles or drop struts to achieve a complete, level stance front and rear.
• Improved Ride Comfort: Despite the aggressive drop, Belltech engineers these springs to maintain a comfortable daily-driver ride quality when installed correctly on the proper application.

Fitment

Belltech 34324 is engineered for 2007+ GM full-size SUVs equipped with factory AutoRide or Magnetic Ride shocks. Per Belltech's published fitment data, this set provides the following drop ranges by application:

• 2015–2020 Tahoe, Yukon, Suburban, Yukon XL, Escalade (with factory Auto Ride / Mag Ride shocks) — 3" or 4" rear drop

Important Fitment Notes: This part number is specific to vehicles with factory AutoRide or Magnetic Ride electronic suspension. If your GM SUV does not have factory electronic shocks, a different Belltech part number is required — for example, 07–20 Yukon XL and Suburban without Auto Ride use a separate set that also offers 3" or 4" drop. Always verify your factory suspension option before ordering. Belltech notes it is not liable for parts purchased for the wrong application.

Frequently Asked Questions

Q: Will Belltech 34324 work on my GM SUV if it does NOT have AutoRide or Magnetic Ride shocks?
A: No — part #34324 is validated specifically for GM full-size SUVs equipped with factory AutoRide or Magnetic Ride electronic shocks. Belltech offers separate coil spring sets for the same body-style trucks without electronic suspension. Contact our team and we'll point you to the correct part number for your build.

Q: How many drop heights does this kit support, and what's included to achieve them?
A: This kit supports two rear drop heights — you can choose the configuration that suits your build. The package includes both the coil springs and high-quality injection-molded spacers, so both height options are available in a single purchase without needing to buy additional hardware.

Q: Does this kit include bump stops, or do I need to purchase them separately?
A: Belltech includes OEM-quality bump stops with the 34324 kit. This ensures your suspension travel is properly limited after lowering without requiring a separate purchase.

Q: Can I combine these springs with other lowering components for a more aggressive drop?
A: Yes — Belltech's product documentation notes that the Pro Coil Spring Set can be combined with other lowering components (such as front drop spindles or struts) for additional total vehicle drop. Reach out to our fitment team to discuss a complete lowering package for your GM SUV.
