Install Instructions

Spring-Things Installation

These instructions show a real-world install on a typical truck (not a showroom-clean frame). Installation does not require suspension disassembly and no alignment is required.

Estimated install time: 15–30 minutes for most users (first-time DIYers may take a little longer).

Tools Required

  • Floor jack
  • Jack stand
  • Wheel chocks
  • Flat screwdriver or small pry bar
  • Side cutters (for trimming zip ties)

Safety note: Always follow basic safety precautions when working under a vehicle.

Step 1 – Prepare the Vehicle

Park on level ground, set the parking brake, and place wheel chocks in front of and behind the front tires to prevent movement.

Jack up the left rear of the vehicle by the frame rail until the rear tire is just slightly off the ground.

Step 2 – Support the Vehicle (IMPORTANT)

Place a jack stand under the frame rail for safety.

IMPORTANT: The vehicle must be lifted by the frame, not the axle. Lifting by the frame allows the rear suspension to decompress so the leaf springs can be separated properly. If lifted by the axle, the weight remains on the springs and they cannot be spread apart correctly.

Step 3 – Prepare the Spring-Thing

Insert the supplied heavy-duty zip tie through the holes in the Spring-Thing pad before installation.

Step 4 – Create Space Between Leaf Springs

Carefully wedge a flat screwdriver or small pry bar between the leaf springs just enough to create a small gap.

Step 5 – Install the Spring-Thing (IMPORTANT)

Place the pad between the leaf springs, ensuring it sits flat and properly aligned.

Pull the zip tie ONLY until snug.

DO NOT over-tighten the zip tie. The pad must be able to move slightly with suspension travel. The factory spring clamp holds one side in position; the zip tie is for alignment only, not clamping force.

  • ✅ Correct: Pad can be shifted slightly by hand
  • ❌ Incorrect: Pad is clamped tightly and cannot move

Step 6 – Repeat on Opposite Side

Repeat Steps 2–5 on the opposite rear leaf spring. Remove the jack stand and lower the vehicle.

You’re now finished — squeak free.

  • No alignment required
  • No suspension disassembly
  • Install time: ~15–30 minutes

Received the unit for my 2024 Chevy 3500HD which was making a grunt/grind noise as the body rocked side to side going slow. The dealer replaced the plastic pad between the spring which cured the issue for about a week, this told me that was the issue. Took me about 45 minutes to install without removing the wheels, most of this was setup and take down time. I found that 2 large flat blade screwdrivers worked well, pry up with one, slide the second in to hold the spring up, cleaned between the springs then installed, really easy, then reverse the process to remove the screw drivers. I knew as soon as I moved the truck this resolved the issue. I have driven the vehicle now for about a week and still quiet. The issue annoys the heck out of me, this product took care of the problem. I contacted the dealer to let them know the GM fix worked temporarily but the issue returned, let them if others have the same issue, here is the fix. Highly recommend this product if you have this issue.

Thank you, Gary! We appreciate your detailed review and are glad to hear the Spring-Thing kit resolved the spring noise issue on your 2024 Chevy 3500HD. Thank you for sharing your installation experience and tips for other customers. We truly appreciate your support and your recommendation!

I have a 2025, Chevrolet Silverado 2500 Custom with 3,500 miles that starting having loud noise in rear end while making slow turns and going over uneven terrain on road, driveway, etc. At times the noise sounded like the entire truck bed was loose. The dealership didn’t see any issues. I decided to give these a try after reading other customer’s reviews and glad that I did! The loud clunking noise is gone! Thank you Spring-Things! Easy install!

Thank you Adam! We really appreciate the detailed review. Those rear-end noises on newer trucks can be incredibly frustrating, especially when the dealership can’t pinpoint the issue. Glad the Spring-Things kit helped quiet things down and made your truck feel solid again. Thanks for giving us a try and for sharing your experience!
