anyway to raise towing capacity?

The correct way is to purchase the right tool for the job. Look to Chev, Dodge, or Ford.
If it's a one time deal think about a rental. Otherwise get yourself a good luck charm and LOTS of insurance coverage.

Here are my posts on heavy towing with the Gen1 Ridgeline,; but keep in mind that this is with the 2009 model year Ridgeline that has the factory hitch, upgraded engine, and improved transmission:

• Figuring out your actual capacity, per Honda's manuels
• Exceeding your tow capacity
• How best to tow a heavy trailer

In short, it's more about the GCWR than the 5,000 lbs tow rating. At least that's what I've learned through trial and error with my Ridgeline.

Keep in mind if you're over GVWR, and there is an accident, insurance determines you were, they could deny the claim.

You're Ridgeline already has upgraded trans & power steering coolers, I know of no "spring" or more correctly coil over upgrade for suspension upgrade over stock. Additionally the Brakes would be a weak link, along with the fact that all reports of towing near the limit, the engine/trans will be struggling at best.

I have used my 2007 and 2014 in our construction business many times per week to tow at or near 5000 lbs, sometimes more weight for short distances. The 2007 was recently sold with 237K very hard miles on it. As of two weeks ago, I have a 2019 RTL-E which seems just as capable as the G1.

The Ridgelines can handle both payloads and towed loads far more gracefully, without the squat that you see in domestic brands. That said proper and timely maintenance, a properly loaded trailer, a weight distributing hitch and a properly calibrated brake controller are key if your truck is loaded with family and luggage while towing.

• 10K lb double axle LoadTrail dump trailer (very underloaded) with electric brakes on both axles
• 12K lb double axle Wells Cargo trailer (very underloaded) with electric brakes on both axles
• AR210 Yamaha jet boat with hydraulic surge brakes on one axle
• 21' Bigfoot fiberglass travel trailer with electric brakes on both axles

If you are looking to upgrade the tow capacity, you will need to do the following:
Increase brake size and calipers
Stronger wheels
Transmission intercooler
Structurally improve chassis
Regear differentials
Different suspension

in short, for a framed vehicle, about $15k in improvements. Don’t exceed the towing capacity of your Ridgeline, and if you do, be aware you are a danger to yourself and those around you.
