Granite: 3S V3 vs 223S

Is the Granite 223S a renamed 3S? Horizon Hobby's spec sheets and exploded views say no: motor, ESC, drivetrain, servo, chassis and body all have new numbers.

V3
ARA4302V3T1 vs 223S
ARA4302V4T1

ARRMA 1/10 GRANITE 3S 4X4 RTR Brushless Monster Truck (discontinued by the manufacturer) (checked 2026-09-25, source) vs ARRMA 1/10 GRANITE 223S 4X4 RTR Brushless Monster Truck (checked 2026-09-25, source). The newer truck's SKU is in the V4 series, but Horizon names it "223S" rather than "V4", so this page does too.

In short

The name change hides a real rebuild. Start at the center of the truck: the V3 diagram shows a 57T slipper clutch set (ARA311034), while no named part on the 223S diagram is a slipper part, and it lists a 57T metal center differential instead (ARA311165), mounted on an aluminum plate made for it (ARA311192).

Power goes through different hardware too. The V3 pairs a BLX100 ESC (ARAM0160) with a separate SLR300 receiver (SPMSLR300); the 223S diagram lists a single 80A ESC/receiver unit (SPMXSE8010RX). The motor on both is a Firma 3660 can, but the Kv is listed as 3200 on the V3 (SPMXSM2000) and 3100 on the 223S (SPMX-1081). For steering, the 7 kg S651 servo (SPMS651) becomes the 18 kg S662 (SPMS662), and the servo saver moves from a 23T spline (ARA340181) to 25T (ARA340215).

The composite chassis gets a V2 part number (ARA320607 to ARA-2148), and the painted bodies change part numbers too: the V3 diagram lists a body clip retainer (ARAC3445) and bodies such as ARA402306, while the 223S bodies, such as ARA-1622, are named "clipless". On the spec sheets, the battery connector line drops EC5 and lists IC5 only, while LiPo compatibility is 2S and 3S on both. The V3 page gives its weight as a bare "6.23" with no unit; the weight row shows both figures as printed, but without a unit we can't say how much the weight changed.

Sources for this summary: the V3 and 223S exploded-view part lists plus the two spec sheets, nothing else. We haven't driven either truck, and a new part number on the diagram doesn't by itself mean the truck behaves differently.

Names are taken from each part's own Horizon Hobby product address, lightly de-hyphenated. Not shown here: 13 screws, shims, bearings, pins and similar small hardware , 8 part IDs that don't fall in any group above , 3 part IDs with no product address in our archive — they are all in the full lists further down.

Spec diff (44 fields: 11 changed · 17 listed only on V3 · 1 listed only on 223S · 15 same)

The 223S page publishes far fewer spec fields than the V3 page did (pinion, spur, final drive ratio and track widths are among the ones it leaves out), so many rows below are "not listed" on one side.

changed not listed = only one generation's official page publishes this field (not a claim it was added or removed) not directly comparable = both pages list it, but on a different basis or likely under the wrong label (see the note under the row) no marker = same value, official wording may differ

Exploded-view parts diff

Every part ID on each generation's official exploded-view diagram, deduplicated and compared as sets. "Not on this generation's exploded view" means Horizon's current diagram doesn't list it; it doesn't by itself prove the physical part changed.

New on this generation (53)

Not on this generation's exploded view (45)

Shared part IDs (73)

Part IDs link to the manufacturer's own product page for that part number; an unlinked ID is one the manufacturer has no page for. The exploded-view diagrams label parts by number only, so this full list shows numbers. The system-by-system section above takes each name from the address of Horizon's own product page for that part, and nothing else.

Other comparisons: ARRMA Mojave 6S: V2 vs V3, ARRMA Kraton 6S: V5 vs V6, ARRMA Notorious 6S: V5 vs V6.
