Direct Replacement for Firestone Ride-Rite 2613
The RETRUE kit is engineered as a direct replacement for the Firestone Ride-Rite 2613 air helper spring system.
This allows owners to replace worn air bags or install a compatible load-support system using factory-style mounting locations without extensive fabrication.
What’s Included?
The package includes:
- Two rear air springs
- Heavy-duty mounting brackets
- Air tubing
- Inflation valves
- Mounting hardware
- Step-by-step installation instructions
An onboard air compressor or wireless air management system is not included, but can be added for convenient in-cab pressure adjustment.
5,000 Pounds of Load-Leveling Support
The RETRUE system provides up to 5,000 pounds of load-leveling capacity, helping maintain factory ride height while towing or hauling.
Benefits include:
- Reduced rear suspension squat
- Improved steering response
- Better trailer stability
- Improved braking balance
- Reduced suspension compression
- Increased driver confidence when towing
The 5,000-pound rating refers to suspension support only and should never be interpreted as increasing the truck’s legal load ratings.
Adjustable Air Pressure (5–100 PSI)
The air springs can be adjusted anywhere between 5 PSI and 100 PSI, allowing owners to fine-tune suspension support for varying loads.
Advantages include:
- Softer ride when unloaded
- Additional support under heavy payloads
- Adjustable ride height
- Improved load balancing
- Better towing performance
Running the proper air pressure helps maintain level suspension geometry and consistent handling.
Improved Towing Stability
Adding rear air helper springs can significantly improve towing dynamics by helping the suspension operate within its intended range.
Potential improvements include:
- Less rear-end sag
- Reduced trailer sway
- Less body roll
- Improved cornering stability
- Better headlight aim
- Reduced bottoming out over bumps
These benefits are especially noticeable when towing travel trailers, horse trailers, enclosed cargo trailers, or carrying heavy bed loads.
Easy No-Drill Installation
One of the biggest advantages of the RETRUE kit is its bolt-on installation.
Installation features include:
- No drilling required
- Pre-drilled mounting brackets
- Clearly labeled hardware
- Vehicle-specific instructions
Many experienced DIY truck owners can install the kit using standard hand tools over the course of an afternoon.
Air Helper Springs vs Factory Suspension
| Factory Suspension | RETRUE Air Helper Springs |
|---|---|
| Fixed spring rate | Adjustable air support |
| Rear squat under heavy loads | Helps maintain factory ride height |
| Limited towing adjustment | Adjustable from 5–100 PSI |
| More body roll | Improved stability |
| Standard suspension only | Supplemental load support |
Air helper springs work alongside the factory leaf springs rather than replacing them.
