RPM Rear A-arms for the Associated B6 & B6D are designed with the same principles as our Flat Front A-arms (RPM #81372) & Gull Wing Front A-arms (RPM #81422). With stock A-arms, the amount of slop at the hinge-pins can cause your suspension settings to wander (we found as much as 0.003” or .076mm of clearance in the hinge pin holes of a stock set of new A-arms). RPM hinge-pin holes are held to strict tolerances, with no more than 0.0005” to 0.001” (.013 to .025mm) of clearance, an improvement of nearly 300% over stock!
How about weight reduction? RPM B6 / B6D A-arms are 4.75 grams per A-arm* lighter than stock! That’s a weight savings of 9.5g in total (almost 1/3 of an ounce)! If your B6 is already underweight, a weight savings at the A-arms means you can add more weight where it’s needed elsewhere, providing additional tuning options and ultimately, a faster racing machine.
RPM arms are some of the toughest in the industry so a rough landing or an extreme hit from an out-of-control competitor won’t take you out of the race! With unmatched performance, extremely lightweight materials and the ability to hold your suspension settings crash after crash, RPM A-arms will get you across the finish line EVERY time!
Tech Notes: RPM #81112 Rear A-arms replace stock Associated #AS91695.
*Weight savings comparison includes hinge pin retaining hardware.
