You asked for it and now RPM has responded with front left A-arms for the Traxxas Summit 1/10 scale trucks. As you may know, the front right A-arms for the Traxxas Revo (RPM #s 80212 & 80215) already fit the Traxxas Summit. But because of the extended T-Lock differential on the Summit's left side, the Revo front left A-arms wouldn't fit. These new front A-Arms fix that issue. RPM has revamped the cross-brace to clear the T-Lock differential so the Summit front left A-arms will allow full suspension travel and thus greatly improve suspension durability. Like all RPM parts, the front A-arms for the Traxxas Summit are molded from RPM's indestructible blend of engineering grade nylons for the best performance and maximum durability. All RPM molded parts are made here in the USA and carry a limited lifetime warranty against breakage. Stop replacing broken plastic stock parts and give RPM a try today.
