This aftermarket upper arm assembly is made for HPI Savage platforms and serves as a direct-replacement, scale RC accessory intended to alter front and rear link geometry. The component centers on an alloy adjustable upper arm paired with a titanium-look tie rod design, and it ships with Delrin collars, mounting screws and a hex wrench to assist basic installation and alignment.
The part is intended to affect roll center and camber link behavior when used in the vehicle’s suspension linkage; swapping to a machined alloy arm increases mounting rigidity compared with many stock plastic arms, while Delrin collars provide a low-friction pivot interface for the tie rod joints. Fitment and orientation follow the existing mounting points on the listed Savage variants, so installation focuses on replacing the stock arms and trimming linkage lengths for desired handling changes.
Installation notes: reuse compatible ball studs and bearings from the vehicle where applicable, verify thread engagement with the supplied screws, and make small incremental adjustments while testing to observe steering and suspension response. This is an RC-scale part and should be used only on the indicated chassis models.
As an alloy upper arm option for HPI Savage platforms, this item targets hobbyists making incremental tuning changes to suspension geometry or seeking a stiffer mounting link; the included Delrin collars, screws and hex wrench cover basic hardware needs during replacement.
