Honda FL5/DE5 ADS Module 39381-T60-G01/39381-31M-A03

Genuine Honda Adaptive Damper (ADS) Module - DE5 Integra Type S (39381-31M-A03)

Here's a trick a lot of Integra Type S owners don't know about: the DE5 and the FL5 Civic Type R use the same adaptive damper hardware but different control modules, and the modules swap between the cars. Fit the FL5's module to your DE5 and the car takes on the Type R's firmer, more track-focused damping, in every drive mode, without coilovers, wiring, or coding. This is the genuine Honda ADS module (part 39381-31M-A03), and it's the cleanest way to change how your Integra Type S rides before committing to a full suspension setup.

What The ADS Module Actually Does

The adaptive damper system (ADS) is what lets your Type S change its ride between Comfort, Sport, and Sport+, the dampers have electronically controlled valving, and this module is the brain telling them how firm to be and how fast to react in each mode.

The DE5 and FL5 share the same physical dampers but run different control modules with different damping maps. Honda tuned the DE5's module softer and more compliant (the Integra Type S is positioned as the more livable, grand-touring of the two), and the FL5's module firmer and more aggressive (the Civic Type R is the sharper track tool). Swap the module and you swap that tuning: the hardware stays, but the car's damping personality changes to match whichever module is installed. It doesn't change ride height, it changes how hard and how fast the shocks react.

Firmer For Track, Or Keep It Compliant

Which direction you go depends on how you use the car.

Most DE5 owners fitting an ADS module want the FL5 (Civic Type R) module, it firms up the damping toward the Type R's more track-focused tune, sharpening body control for track days, canyon runs, and hard driving, while still keeping your factory Comfort, Sport, and Sport+ modes (each just gets firmer). It's the move if you find the DE5 a touch soft for how you drive it.

The swap works the other way too: an FL5 owner who finds the Type R too stiff on rough roads can fit the DE5 (Integra Type S) module for a more compliant, comfortable daily ride. Each module brings its own maps, so the car takes on that model's character.

Why This Is The Smart First Move

Before you spend on coilovers, this changes the car's damping character for the cost of a module and a few minutes of work, while keeping the entire factory adaptive system intact.

That's the real appeal: you keep the OEM adaptive damping, the drive modes, and all the factory safety and integration logic, you're just changing the tuning the system runs. Coilovers replace the whole system and often lose the adaptive behavior; this keeps it and retunes it. For a lot of owners, this module paired with a set of Swift lowering springs is the sweet spot, a genuine suspension change that still rides and behaves like a factory-engineered system.

Plug-And-Play, Fully Reversible

The install is genuinely simple and risk-free to try.

It's a direct plug-and-play swap using the factory connectors and mounting, no extra wiring, no relays, no cutting, no coding. You unplug your original module, plug this one in, and bolt it back in place. Installed correctly, it communicates properly with the factory system and won't throw warning lights.

And because it's a straight module swap, it's fully reversible, if you don't like the change, unplug it and reinstall your original. That makes trying a different damping tune genuinely low-risk: you're not modifying anything permanent, just swapping the brain.

Fitment

2024-2026 Acura Integra Type S (DE5), also compatible with the 2023-2026 Civic Type R (FL5)

Genuine Honda ADS module, part number 39381-31M-A03. The DE5 and FL5 modules are cross-compatible. Plug-and-play, fully reversible.

This is for the DE5 Integra Type S owner who wants to change how the car rides, usually firmer and more track-focused by fitting the FL5 Civic Type R module, without jumping straight to coilovers or touching the wiring. It's the genuine Honda part, a plug-and-play swap that keeps your factory adaptive dampers, drive modes, and safety logic fully intact, just running different damping maps, and it's completely reversible if you want to go back. Pair it with Swift springs for a real suspension change that still behaves like a factory system. We run these on our own cars because they let us retune the damping with OEM reliability and zero risk.

Fits: 2024-2026 Acura Integra Type S (DE5); cross-compatible with 2023-2026 Civic Type R (FL5). Part number: 39381-31M-A03 (genuine Honda). Function: controls the adaptive damper valving/damping maps; swap to change the car's damping tune (FL5 module = firmer/track, DE5 module = softer/street). Does not change: ride height. Install: plug-and-play, factory connectors, no wiring or coding, fully reversible. Pairs with: Swift lowering springs.

The Swift springs link (pre-filtered to the FL5/DE5 fitments) is now in two spots: the "smart first move" section where the module-plus-springs combo is the natural recommendation, and the spec line's "pairs with." That restores the original cross-link that got lost, and it's a genuine pairing, the module retunes the damping, the springs drop the ride height, together they're the "real suspension change without coilovers" the description describes. That completes the rewrite: de-stuffed, DE5-focused for the "integra type s ads module" term, distinctive enough to re-establish your page as the original over the copies, OEM part number throughout, and the Swift springs cross-link back in.
