The RPM Baja Rey Front Upper & Lower Suspension Arm Set is lightweight, extremely rigid, re-engineered for performance and add adjustability where there isn’t any with the stock arms.

When RPM 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. So RPM designed their arms to be rigid and silky smooth throughout the full range of travel with a redesigned upper A-arm shape. The shape eliminates the bind while adding extra clearance at the pivot ball. The ultra tough materials 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. RPM has 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 RPM's 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!

Features:

  • Added extra outboard shock mount
  • Redesigned upper A-arm shape eliminates bind
  • Replaces stock Losi LOS234004
  • Sold with 2 – upper front A-arms and 2 – lower front A-arms
  • Stock Losi A-arm pivot balls required (not included)

NOTE: 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 the Super Baja Rey.

RPM Baja Rey Front Upper & Lower Suspension Arm Set
Installed exactly as described in the instructions on my Losi Baja Rey 2.0 and one of the lower a-arms broke after less than a WEEK of driving casually in my backyard. Additionally, with these control arms having revised geometry, they caused my steering to bind when turning left. The stock Losi a-arms lasted me through a year of regular bashing before breaking. I have other RPM products that I'm happy with, but I'd avoid this part!

Great look and fit! Nothing new with rpm suspension arms. You have to do a little sanding!!! No big deal. The back hinges pin supports, you have to sand maybe 1mm total on both ends of the back end pin support. Took me 3 minutes if that long. Sand/file just till the arm loosens up!

I've tried a lot of things and these are the best thing for handling as far as using your baja rey on a track. sometimes you have to dremel a little bit off the back of the lower arms to not collide with the pin holder. if you countersink and use flat head screws with a little loctite for the back pin holder that strengthens everything. Like anything plastic you have to replace them after a while. The Baja Rey is a heavy powerful truck. I like this product and don't have any substitute for what I do.

RPM Baja Rey Front Upper & Lower Suspension Arm Set
I wish I would have replaced with stock arms. These limit suspension travel in the front and are not smooth on the bottom like the stock ones, allowing more dirt and rock to get into the truck and getting hung up and snagged over rough terrain. Would not recommend.

RPM Baja Rey Front Upper & Lower Suspension Arm Set
Not much better than stock. It is nice having options for the suspension though. Better than stock but only for that reason. Not what I'm used to from RPM.

RPM Baja Rey Front Upper & Lower Suspension Arm Set
Always was a fan of rpm products but it seems for the baja rey 1/10 ford raptor i am going on set number 3 and all sets have consecutively broke at the forward lower a arm runner thinking that for the price and how much they break it may be cheaper and more cost effective using stock and or finding a steel or aluminum aftermarket. thought they do look a lot nicer then the stock but they are simply not beffie enough to handle the front impacts. Again not saying they will break every time but they did not hold up very well for myself.
