On Titan's feature lists the two sprayers match except for one item: Titan lists DigiTrac diagnostics against the 840I and ActivGuard integrated GPS tracking, which needs a subscription, against the 840IA. Delivery, tip size, pressure and motor are the same. Each comes as a high rider or low rider with its own part number, and the wear parts come from the Impact 840 diagram pages.
What the 840I and 840IA have in common
Both are Impact IntelliSync sprayers, the Bluetooth generation of the Impact line that talks to Titan's MyTitan app. They are not the original Impact 840, and they are not Impact X models, so use the Impact 840 pages on this site and not an Impact X page. On the specs Titan publishes, the 840I and 840IA are identical:
Impact 840I and 840IA shared specifications (Titan)
| Item | Both models |
|---|---|
| Maximum delivery | 1.00 gpm |
| Maximum tip, one gun | 0.032 in. |
| Maximum tip, two guns | 0.021 in. |
| Maximum pressure | 3300 psi |
| Motor | 2.3 hp brushless |
| Titan's weekly volume | 200-300 gallons |
The weekly volume is Titan's recommendation for how much the sprayer is built to handle, not a limit. The original Impact 840 carries the same delivery, tip and pressure figures.
Titan also lists the same core pump features for both: Quad+ Packings, the PermaLife Cylinder, the AutoOiler and Electronic Pressure Control with Rapid Clean. Titan describes the PermaLife Cylinder as a non-replaceable design, so the parts you will actually buy for the pump are the packings, seats, balls and piston rod around it.
What Titan lists for the 840I
Titan's page for the 840I lists the IntelliSync Bluetooth connection to the MyTitan app, Logix Adaptive Pressure Control and a DigiTrac diagnostics display. Logix is the tip-sensing control: Titan says it adjusts pump speed and power based on the tip size you have fitted. DigiTrac is the display that shows pressure readings and counters you can reset.
DigiTrac is not new to the IntelliSync line. The original 840's diagram on this site also lists a Digi-Trac display, part 805-401, with fitment that names the 840, 840I and 840IA. So a DigiTrac display is not what makes an 840I different from an older 840; the Bluetooth link and Logix control are the additions Titan lists.
What Titan lists for the 840IA
The 840IA adds ActivGuard, Titan's integrated GPS tracking. Titan says it needs a subscription, and we do not list subscription terms or cost here; check Titan's page or ask before you buy if tracking is the reason you want the IA.
Titan's listing does not say the 840IA lacks anything the 840I has. Both are IntelliSync models with the Bluetooth link, so if you are choosing between them, the question to answer is whether you want GPS tracking on the machine. If you do not, nothing in Titan's spec list gives the IA an advantage on delivery, tip size or pressure.
The four configurations and their part numbers
Each version is sold as a high rider and a low rider. These are the sprayer part numbers as the site lists them, useful for matching what is on your invoice or the tag on the cart:
Impact 840I and 840IA configurations
Those numbers identify the whole sprayer. For repair parts, use the diagram pages below.
The high rider and low rider differ in the cart, which matters when you order a wheel or a handle. The upright cart (0552537A) and the low rider cart (805-289A) have separate diagram pages, and the high rider's cart 0552538A lists fitment for the 840, 840I and 840IA.
Ordering parts: one set of 840 diagrams
The site does not split the 840I and 840IA into separate diagrams from the 840. Parts lists that matter for repair carry fitment notes such as "Impact 840 I and IA" or "840I, 840IA", and you open the Impact 840 pages to find them. Here are examples where the listing names both IntelliSync versions:
840I and 840IA parts to check against the 840 diagrams
Open the drive assembly, fluid section and main assembly pages and find the numbered callout for the part you need. Wear items such as piston lube, tip seat kits and gun filters are on the accessories page. Titan's owner's manuals are on our manuals page.

The Short Version
The Impact 840I and 840IA share their delivery, tip, pressure, motor and pump features. Titan lists DigiTrac against the 840I and ActivGuard GPS tracking, with a subscription, against the 840IA. Use the Impact 840 diagram pages for parts, and call (713) 931-0006 with your model and serial number if you are not sure which version you have.
