Description
The RPM Arrma Upper/Lower Left Front Arms (RPM81579) deliver a stronger, more predictable suspension upgrade for ARRMA 6S platforms. Finished in red, this left-hand pack includes one upper and one lower front A-arm, moulded from RPM’s engineering-grade nylon for long-term durability.
Updated for V5 and EXB geometry, these arms are significantly beefier than earlier RPM 6S designs: lower arm beams are approximately 30% thicker and upper arms over 22% thicker to cut flex and sharpen handling. An additional outboard shock-mount hole enables a lower-profile setup to drop ride height and lower the centre of gravity. The upper arm removes caster spacers and widens at the inner hinge pin to create a more stable “A” shape for improved steering feel, strength and durability.
Suggested compatibility covers V5/EXB editions of the ARRMA Kraton, Notorious, Talion, Fireteam and Outcast, with reverse compatibility for earlier versions noted below.
Features
- Stock-replacement design for V5/EXB models (suggested compatibility)
- Extra shock-mount hole for added suspension versatility
- Fits most 6S version models (suggested compatibility)
- Sold as one upper and one lower in each package (left front)

RPM Arrma Upper/Lower Left Front Arms - Red - 6S Kraton/Outcast/Fireteam Manuals & Guides
Specifications
RPM 6S Front A-arms fit V5 / EXB editions of the ARRMA Kraton, Notorious, Talion, Fireteam & Outcast. The design modifications we incorporated accommodate changes made by ARRMA for V5 and EXB versions of these vehicles. However, they are reverse compatible for older models.
Beefier: Our A-arms are significantly beefier than our original 6S version A-arms. Lower A-arm support beams are 30% thicker while upper A-arms are more than 22% thicker. The added thickness not only improves durability and strength, it also reduces flex. Less flex equates to more predictable suspension performance and handling.
Extra Suspension Options: The lower A-arm has an added shock mount hole further outboard. This additional position provides a lower profile suspension set-up. The shocks lay down a little further, dropping the ride height for a lower center of gravity. A lower center of gravity equates to higher corner speeds.
Caster Clip Elimination: As for the upper A-arm, we eliminated the caster spacers. This gave us room to widen the arm at the inner hinge pin mount. The extra width creates more of an “A” shape, stabilizing the upper A-arm. A more stable A-arm improves steering and suspension performance while adding strength and durability.
All RPM A-arms are molded from our nearly indestructible blend of engineering grade nylons. Tough materials equate to performance you can rely on when the conditions are at their worst!
Tech Notes: RPM ARRMA Kraton, Talion, Notorious, Fireteam & Outcast A-arms are sold as one upper and one lower in each package. One left and one right package is needed for each vehicle. Our A-arms replace the upper arms from ARRMA 330655 and the lower arms from ARRMA 330656.
Version Notes:
V5 & EXB models: Stock replacement A-arms for ARRMA 330655 and ARRMA 330656.
V4 and earlier models: Requires 1 – ARRMA ARA713032 Shock Mount Pin & 1 – ARRMA ARA330645 End Cap. Replaces stock ARRMA AR330218 & AR330219.
