ARC Raiders Stash Guide: Storage Upgrades and Inventory Tips

ARC Raiders Stash Guide: Storage Upgrades and Inventory Tips

The stash in Speranza is where extracted loot and anything you craft actually stays after a raid. After Frozen Trail on October 8, 2026, Coin purchases on the Expand button take that grid from a 64-slot start to a 328-slot maximum. That 328 figure leaves out Expedition rewards and Nomadic Envoy space.

Open the inventory, switch to the Stash panel, and use Expand at the top of the grid. The next Coin price is shown before you confirm, and each purchase adds 24 slots immediately. No quest and no Outpost project stands in front of that buy. A full extract still fills the grid fast. Split ammo, workshop parts, and other loose stacks each take a row until you merge or sell them.

Each Expand purchase adds 24 slots and is paid in Coins

A new stash starts at 64 slots. Every Expand purchase adds 24. The first four rungs are:

5,000 Coins to reach 88

10,000 Coins to reach 112

15,000 Coins to reach 136

25,000 Coins to reach 160

Frozen Trail added two more rungs above the old 280-slot stop. Reaching 280 now costs 300,000 Coins. The step from 280 to 304 costs 750,000, and the step from 304 to 328 costs 1,500,000. Those three payments use the same Expand button as the early rungs, and they are paid in Coins only. That is the currency behind ARC Raiders Coins for sale when the 750,000 or 1,500,000 step is on the button.

328 is the Coin cap, not the whole grid

The Coin ladder is only one way the grid grows. The other sources either stack on top of that 328 or sit in a completely different cupboard.

Expedition +12 grants are still on the account

Each completed Expedition grants 12 stash slots, and Embark caps that bonus at 60 after five Expeditions. Those grants are exactly what the 328 figure leaves out, so a Raider who finished all five is working with the Coin cap plus up to 60 more on the same grid.

The fifth Expedition window closed on September 29, 2026 at 10:00 CEST. Embark has paused further Expeditions until early 2027, when the project is due back with larger changes. Consecutive Expedition buffs already earned stay in place during the pause. The 328 figure still leaves Expedition rewards out, so those finished +12 grants continue to sit on top of the Coin ladder.

Cassio’s two expansions reset if you depart

From Level 25, the Nomadic Envoys in Speranza sell stash expansions that sit outside the 328 Coin cap. This extra space resets if you depart on an Expedition. Two expansions are offered, each adding 12 slots. The first takes high-tier ARC parts totaling 200,000 item value; the second takes 400,000. The trade wants those high-tier ARC components, not loose weapons or low-tier junk.

Frozen Trail sent Ermal back on the trail and put Cassio at the stall. Cassio still runs the expansions, the weekly barters, and the trader quests. Expeditions are paused until early 2027, so no departure window is open that would clear those purchased slots today. When Expeditions return, that reset still applies to Envoy space.

Outpost furniture does not use stash slots

The Outpost is a separate room you unlock through a project, and the furniture you place there is a second storage pool. Accept the project quest and take a Camera with you; the first step is a photograph of a farmland house. Shani sells the Camera for Coins, and it can also be crafted at the Workbench or found Topside.

Furniture Designs behave like blueprints: once learned, you craft the piece and place it with Decorate. Each piece lists how many slots it holds, including full stacks, and you can clear attached items back to the stash in one action. Expanding the Outpost opens more rooms and more furniture points, which is how spare guns and bulky kits leave the main grid without being sold.

Set Safe Pockets before you leave Speranza

Safe Pockets are the slots that come back with you if you go down Topside. A standard Safe Pocket holds one item or one stack, and it will not take a weapon. Augments cannot be removed or swapped once you have deployed, so the pocket layout has to be set in Speranza.

l The Free Loadout Augment is the thin end: 14 backpack slots, a 35 loadout-weight cap, Light Shields only, and no Safe Pockets. Whatever sits in that pack is gone if you fail to extract.

Looting Mk. 2 gives 22 backpack slots, a 60 loadout-weight cap, Light Shields only, and two standard Safe Pockets.

Looting Mk. 3 (Cautious) gives 24 backpack slots, a 70 loadout-weight cap, and two standard Safe Pockets. It accepts Light Shields only, includes Integrated Binoculars, and automatically administers a weak Adrenaline Shot when the shield breaks, on a fixed cooldown.

Looting Mk. 3 (Survivor) gives 20 backpack slots, an 80 loadout-weight cap, and three standard Safe Pockets. It accepts Light and Medium Shields, and while you are downed and stationary it regenerates health up to 75% of maximum downed health.

Looting Mk. 3 (Safekeeper) gives 18 backpack slots, a 65 loadout-weight cap, and a single Safe Pocket that can hold any item, including a weapon. It accepts Light, Medium, and Heavy Shields. That is the pocket that can bring a found gun home after a wipe.

Merge stacks after the Vault moved into the stash

Live Update 2.3.0 on October 27, 2026 disabled the Expedition Vault. Everything stored in it moved into the stash, and purchased Vault slots were compensated with Bronze Statuettes. Store Update 2.2.0 had already removed the Vault tab from the menu. If the grid jumped overnight, that transfer is why.

Two Frozen Trail inventory rules are easy to miss while you are still in a raid. You can drop loot to the ground directly from a container, so a crate no longer has to be emptied into a full backpack first. Weapon-slot weight reduction applies only to the loadout; other containers and sub-containers do not get that break, which is why a gun feels lighter on your back than the same gun sitting in a bag you are carrying.

Back in Speranza, the merge control sits to the right of the inventory category filter and collapses split ammo and consumable stacks in one action. Empty the rows that merge frees, then sell or recycle the cheap ARC Raiders Items you are not crafting with. Those Coins are what the Expand button charges.
