Can Roadmaster Comfort Ride System be Used with MORryde LRE4000 Equalizers

Updated 08/10/2026 | Published 08/09/2026

Question:

I have a 2026 Jayco Pinnacle 38FBRK with the following factory running gear: * Tandem Dexter 8,000-lb axles — 16,000 lb total axle capacity * 3-1/2” axle tubes * Dexter ABS + Tow Assist * MORryde LRE-4000 suspension * 4,000-lb leaf springs — 16,000 lb total spring capacity across four springs I’m considering the Roadmaster Comfort Ride Leaf Spring Suspension Kit with Shocks for tandem 8K, 3-1/2” axles, and I’m trying to understand whether it would be a meaningful upgrade over my current MORryde LRE-4000 setup. My main goal is reducing the amount of shock, vibration, and repeated suspension movement that gets transferred into the fifth wheel. I travel frequently on rough interstate and state highways in the West, so I’m more concerned with protecting the trailer structure, cabinetry, appliances, and interior than I am with fixing a handling problem. Would you recommend replacing the entire LRE-4000 system with the full Roadmaster slipper-spring/shock system, or would it be better to keep the LRE-4000 and add only the Roadmaster shock kit? Specifically, I’m trying to understand: 1. What does the complete Roadmaster system do better than the LRE-4000? 2. Does the Roadmaster slipper-spring design allow the front and rear axles to react more independently than the LRE-4000 equalizer system? 3. What advantages does the LRE-4000’s rubber shear/suspension system have over the Roadmaster design? 4. Would adding Roadmaster shocks to the existing LRE-4000 give me the best combination of rubber isolation and hydraulic damping? 5. Are the Roadmaster shocks fully compatible with the LRE-4000’s suspension travel and movement on this specific Pinnacle? 6. If you would recommend the complete Roadmaster system, would the 4,000-lb-per-spring 8K kit be the correct match for this trailer? 7. Is there any concern with compatibility around the Dexter ABS/Tow Assist wiring, axle hardware, or brake system? I’d appreciate your recommendation based specifically on ride quality and reducing shock transmitted into the trailer over rough pavement.

Hey Drew, this is a really great question and I appreciate all of the research and thought you've put into it so far. So the MORryde LRE setup is a really nice cushioned equalizer that in my opinion would provide more cushioning than the slipper spring setup of the Comfort Ride if you went with the full kit. At worst the ride quality is so comparable it wouldn't be worth the extra money so your best option is to go with three of the Comfort Ride Shock Kits for 3-1/2 inch diameter axles part # RM-2470-50. This will make the biggest difference in ride quality and is the best bang for the buck as well so it's definitely your best option. This is also perfectly compatible with the ABS system you have now as well.
