Your cart is empty.Condition-New 2 Sets of RPM 80705 heavy duty front or rear blue suspension a-arms. This is a complete set of 4, for the front and rear. These will fit the following Traxxas vehicles: 1/10 Slash 4x4, 1/10 Ultimate Slash 4x4, 1/10 Platinum Slash 4x4, 1/10 LCG Slash 4x4, 1/10 VXL Stampede 4x4, and 1/10 Rally 4x4. Features: RPM has eliminated the slop in the suspension system, tightening the tolerances around the hinge pins, reduced the fore and aft movement of the A-arms at both the inner hinge pin and at the axle carriers by better than 90% and improved the durability dramatically (they’re made by RPM, enough said). As a bonus, we cut 6.5 grams of weight off of each A-arm! That’s a total loss of just under one ounce of weight simply by replacing your stock A-arms with the RPM versions! We can’t forget about how much better aesthetically the RPM versions look either. RPM A-arms carry over our traditional look with our 30 degree leading and trailing edges, and huge bosses for the shocks and sway bar mounts. RPM A-arms are molded in their trademark blend of incredibly durable nylons and are backed by an industry leading warranty. RPM proudly stands behind our products! Designed, manufactured and produced right here in southern California in the USA! Tech Notes: RPM A-arms for the Traxxas Slash 4x4, Stampede 4x4, and Rally are sold in sets of 1 - left and 1 - right A-arm in each package. Two packages will be needed to complete one truck. The upper hinge pin hole of the rear axle carriers cannot be used (not a stock location for the Slash 4x4) due to strengthening designs that reduce the clearance around the rear axle. Length: 3.96" (100.5mm) Width: 1.79" (45.5mm) at widest point Thickness: 0.31" (8mm)

These work great. I finally snapped one after probably 8 years of the previous one. It was getting worn down from years of rocks and dirt thrown up from the tires. If you don't want to go aluminum, these are definitely the next best thing.

This A-Arms are good, but misleading to say that they fit on a Rustler (they do with some modifications). Basically, the back A-Arms will fit just fine, but the front A-Arms have a hump that touches the driveshaft. And not just barely touches, but touches enough where it prevents driveshaft from moving / turning. It's an easy 30 mins fix. What you have to do is basically grind the A-Arms down to the point the driveshaft does not touch. A Dremel and a grinding stone is basically the easiest and fastest way of doing it. After that, a-arms are great, and bashed the heck out of them, and no breakage. 3 Stars because needs some work to get it to properly fit on a 4x4 rustler.
