RPM front A-arms for the Associated ProLite 4×4 and Thunder Tiger Sparrowhawk / Tomahawk series of vehicles were designed to add some much needed strength and durability to these vehicles. RPM A-arms are manufactured using our trademark blend of extremely tough nylons allowing our A-arms the ability to easily shrug off crashes that would break stock parts.
Other design improvements include the removal of the tiny hinge pin retaining screws in favor of a screw in-line with the hinge pin, significantly strengthening our A-arms. RPM A-arms are manufactured to tighter tolerances as well, meaning we eliminated most of the slop in the hinge pin holes and between the caster block and A-arms. This ProLite 4×4 Front A-arms – Blackmeans camber, caster and toe angle settings will maintain their set positions for a much smoother, more consistent, better performing ride. All stock geometry has been retained for simplicity and ease of replacement of stock parts.
RPM ProLite 4×4 A-arms are designed and manufactured in the United States and come with our limited lifetime warranty against breakage for parts that are sure to perform beyond the most demanding expectations!
