MORRFlate Quad 4-Tire Inflation & Deflation System — Honest Review
Speed up air-downs and air-ups by inflating, deflating, and equalising all four tyres at once.
Quick Take
- What it is: A 4-way hose kit and manifold that let you air down or air up all four tyres simultaneously and equalise PSI.
- Who it’s for: Overlanders and beach/dune drivers who want faster, more consistent tyre-pressure control.
- Why it stands out: Trail-tested brand, plug-and-play with common compressors (ARB, PowerTank), and a clear digital gauge (1–150 PSI).
What We Liked
- Fast & even: Equalises pressure across tyres, reducing hot-spot wear and guesswork.
- Less bending over: Read and adjust PSI from the manifold instead of each valve—saving time and knees.
- Compressor-friendly: Splits flow across tyres so single compressors don’t work as hard.
- Trail-proven: MORRFlate has built multi-tyre systems since 2014—solid rep with off-roaders.
Where It Falls Short
- Space & hose management: It packs into a bag, but you’ll still wrangle multiple lines in tight camps.
- Best under ~125″ wheelbase: The Quad kit is optimised for rigs up to about 125″; longer wheelbases should size up or use extensions.
How It Works in the Real World
Hook each hose to a tyre, clip to the valve stems, then connect your compressor to the manifold. Open the valve to equalise/deflate, or run the compressor to inflate—all four tyres together. The digital gauge lets you watch PSI at the manifold and fine-tune with quick bursts. For sand, we typically drop into the mid-teens, then air back up at the trailhead without playing musical chairs around the truck.

Best Use Cases
- Sand driving: Quick drops to ~12–18 PSI, then fast equalised air-ups.
- Mixed terrain days: Frequent trail-to-highway transitions with minimal downtime.
- Groups & families: Keep the compressor running while you manage tyres from one spot.
Pro Tips
- Lay hoses outside the vehicle path to avoid running them over when repositioning.
- Check couplers for grit after beach days; keep a small brush in the bag.
- If front/rear PSI targets differ, isolate axles and equalise per axle.
Verdict
The MORRFlate Quad is one of the simplest upgrades for anyone who airs down regularly. It trims time at the trailhead, keeps PSI consistent across tyres, and reduces compressor strain. If your wheelbase is within spec, it’s a near no-brainer for sand, snow, and mixed-terrain overlanding.
