A tough truck needs tough parts. RPM Front A-arms for the Baja Rey are the toughest you can get! They're lightweight, extremely rigid, reengineered for performance and add adjustability where there isn't any with stock arms.

When our engineers looked over a stock set of Baja Rey A-arms, they noticed the upper A-arms were very flimsy and cause a bind with the steering spindles at full droop. We wanted to make sure our versions were rigid and silky smooth throughout the range of travel so we redesigned the shape of the upper A-arm. The new shape eliminates the bind while adding extra clearance at the pivot ball. The ultra tough materials we use beef up the upper arm for unrivaled strength and rigidity as well.

With zero shock mount adjustability on stock lower A-arms, it is very hard to tune your Baja Rey to your driving style or terrain. RPM A-arms add an extra outboard shock mount that will give you that added edge under any conditions.

One final, very important fix was to reduce the massive amount of negative camber incorporated into stock A-arms. We found anywhere from -4° to -5° of camber, which is pointless on a 4wd truck which leads to excessive tire wear and loss of traction. We've reduced the negative camber to roughly negative 2° for significantly improved tire wear and overall vehicle performance.

RPM Baja Rey A-arms are designed and manufactured in the USA from our outrageously tough blend of engineering grade nylons for performance that will outlast the rest of your truck! Bolt a set on your favorite ride and smile while your truck looks better, performs better and can handle whatever you throw at it!

Tech Notes: RPM Baja Rey A-arms replace stock Losi #234004 and are sold with 2 - upper front A-arms and 2 - lower front A-arms. Stock A-arm pivot balls are required (but not included - RPM recommends reusing those from your stock a-arms). RPM Baja Rey A-arms will not work on the Super Baja Rey.
