Description
RPM front A-arms for the Associated ProSC 4×4, ProLite 4×4, ProRally 4wd 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 means 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 ProSC 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!
Tech Notes: RPM front A-arms for the Associated ProSC 4×4 replace stock Associated #7157. They also replace Thunder Tiger Sparrowhawk and Tomahawk stock #PD7977.
