Upper Control Arm Race Line


The price shown here is before the upgrades below. 

RPG Offroad Upper Control arms carry over the same design and build quality that you see on modern day race trucks.

RPG Ford Raptor Upper Control Arms are crafted from a 3D Cad design that ends up being CNC laser cut and folded for a precision fit and finish. RPG UCA™s are designed with the future in mind. Unlike other aftermarket control arms available on the market, we dramatically changed the bearing cup angle of the arm to ensure proper geometry to enable the use of aftermarket Coil Over shocks which allows for greater amounts of droop travel. When others UCA™s will bind metal on metal, your RPG unit will allow for a full range of wheel travel without any damaging affects down the road because of the aggressive cup angles used.  This also remains important when moving your OE Raptor shock to the 2nd or 3rd perch setting.

On many of our competitors UCA™s you will also find ½ bolts holding the arm to the spindle or at best a 4340 heat treated center pin. When you opt to go with a Raptor Performance Group UCA Race Line, you will find our center pins are 5/8th 300M material which is 5X™s stronger than a grade 8 ½ bolt, and 2X™s stronger than a 4340 heat treated pin. Our center pins are black oxide coated to help prevent rust and corrosion. If there is one thing we have learned over the years in Baja, it™s don™t gamble with lesser materials.

The third major benefit of choosing an RPG UCA Race Line version is the ease of installation and maintenance on the chassis pivot points. While others use ¾ Heims, we opted to go with 1.0 stainless steel spherical bearings with stainless steel mis-alignments for exact fit and much greater strength. Using fixed spherical bearings eliminates the head ache of trying to nail down a proper alignment and guarantees our arms drop right into place of the old OE Ford UCA.

These arms are perfect for the hardcore off-roader who is looking to get the most out of their setup. You will gain Strength, Longevity and Flexibility for future suspension upgrades to take your current set-up from mild, to wild¦
