RPM A-arms for 4S BLX versions of the ARRMA Kraton & Outcast are designed primary for strength and durability but we've added a few extra features in as well.

First is slop elimination. Our A-arms reduce the amount of movement of the A-arm at the hinge pins, providing for better steering response and more consistent camber, caster and toe angle settings.

Our next improvement is the addition of a second shock mount hole further out on the arm, providing for a lower profile suspension set-up. This shock position allows the suspension to lay down a little further, dropping the ride height for a lower center of gravity and better cornering stability.

Our most important update is durability. Our new A-arms are massive! At almost 25% thicker than stock, our A-arms will take a pounding and come back for more! All RPM A-arms are molded from our nearly indestructible blend of engineering grade nylons for performance you can rely on when conditions are at their worst!

Tech Notes: RPM A-arms for 4S versions of the ARRMA Kraton & Outcast are sold in pairs. Front A-arms replace stock ARRMA #AR330520 while rear A-arms replace stock #AR330521.

Manufacturer: RPM
Part Number: RPM80742

We want to ensure a smooth delivery experience for you, and here are some key details to keep in mind about our service.

  • For orders exceeding £120, delivery is available exclusively to mainland UK addresses. However, orders below £120 can be delivered to outlying Isles and Northern Ireland, provided they meet specific criteria: they must be deliverable by Royal Mail, weigh less than 30kg, and fit within the dimensions of 61cm x 46cm x 46cm. Please be aware that certain highland areas may entail additional delivery fees, as couriers often charge more for these deliveries. If you reside in the highlands or any outlying regions, we recommend reaching out to us before placing your order to verify delivery options and any potential extra charges.
  • Delivery is typically included in the price for the majority of our products, unless otherwise specified. However, please note that orders under £80 will incur an additional delivery charge. You can easily view this charge on the checkout page when finalising your purchase. We aim to maintain transparency in our pricing structure while providing you with the best possible service.
  • Most orders will be delivered via either a next working day delivery service or within 2 working days, depending on your chosen service. Please note that for next working day delivery, the cut-off time is 12pm, and dispatch occurs exclusively on weekdays. However, certain items may have longer shipping times, and the expected delivery period will be clearly specified in the product listing.
  • To streamline your order fulfillment process, please note that when your order includes items with varying shipping times, we follow this approach: If any item in your order has a longer shipping time, we will hold the entire order until all items are in stock. However, if certain items are expected to be restocked after a considerable delay, we offer you two options. You can choose to wait for complete fulfillment, where we'll dispatch the order once all items are back in stock. Alternatively, you have the option to receive a partial delivery, where we'll promptly send you the in-stock items and deliver the remaining items as they become available. Your satisfaction and convenience are paramount, and we strive to accommodate your preferences for multi-item orders.
  • To ensure efficient delivery, we work with trusted carriers: DPD Local for next working day delivery and Royal Mail for the 2 working days option.
  • After dispatching your goods, we'll promptly send you an email containing the parcel's tracking number. To ensure you stay updated conveniently, kindly provide a valid mobile number, which we will add to the consignment. This way, you can receive real-time updates on your mobile phone for added convenience.
  • For listings specifying a shipping time of "Dispatched within 3 working days," please note that orders under this category will typically be delivered within a timeframe of 3 to 5 working days.
