When the updated RAM 1500 EcoDiesel debuted in 2019, it was so much better that it nabbed the coveted Motor Trend Truck of the Year award. However, owners of the 2019-21 trucks are discovering the lightweight composite control arms don't hold up. The blame lies with the large, hollow voids inside the arms that permit them to twist dramatically when driving. The twisting action overloads the bushings, leading to significantly reduced life and increased tire wear. Additionally, the sphere of the ball joint erodes the plastic filling around it, further reducing component life.
Mevotech Supreme Control Arms are a better alternative to the OEM part. They're one solid piece of forged 1045 steel for much-increased stiffness and strength. The sintered metal ball joints have larger spheres to boost contact pressure and ball pin strength, and are surface hardened to prevent premature wear. Zerk fittings allow owners to grease the joints for even longer life, and upgraded bushings contain additional rubber to improve durability and reduce flex for reduced body roll. Mevotech Supreme Control Arms come fully assembled to get you back on the road faster.
