The ARRMA Kraton 8S & Outcast 8S are 26 lbs. (12kg.) of high-flying, dirt shredding, jump-killing fun! If your A-arms aren’t up to the abuse these massive monsters can dish out, look no further than RPM. Our replacement front A-arms are designed with the backyard basher in mind and can handle some serious abuse and come back for more.
Our front lower A-arms have a triple beam style construction designed to spread impact energy across all three beams. Each beam’s cross-section is a whopping 5/8” (15.8mm) tall x 3/8” (9.5mm) wide. These massive beams reduce unwanted flex during normal suspension movement, yet allow impact-absorption during those not-so-perfect landings and crashes. We also moved the inner cross brace away from the chassis, eliminating the droop stop entirely. While this may seem counter-intuitive, our test truck’s chassis was bent at the droop stops, clearly illustrating that extreme impacts were too much for the chassis plate to handle. After all, there’s not much worse than a bent chassis.
Our front upper A-arms use a dual beam construction where each beam is a massive 1/2″ (12.7mm) tall x 3/8” (9.5mm) wide. We eliminated the tube shape over the hinge pin to eliminate built-in molding stresses while beefing up the leading edge hinge pin support to add some much needed strength and durability.
Both upper and lower A-arms are molded with fingernail slots that allow easy access to remove the aluminum support ring (not included) at the pivot ball. Made in the USA from our trademark blend of ultra durable materials, you can’t go wrong with RPM!
Tech Notes: RPM A-arms for the ARRMA Kraton 8S & Outcast 8S are sold as one upper and one lower in each kit. One left (RPM81522) & one right (RPM81562) will be needed to complete the front end of one vehicle. RPM A-arms replace the upper A-arms from stock ARRMA ARA330561 and the lower A-arms from stock ARA330589.
Installation Notes:: Like stock A-arms, RPM Kraton 8S versions are sold without threads. If the pivot ball hole is difficult to thread using the pivot ball, RPM recommends thread tapping (tap not included) the hole for 3 – 4 threads, but do not tap any further. Additional cut threads will negate the thread-locking capability of our materials.

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.
