If you’re thinking of lifting your vehicle these arms are a must. These upper control arms increase caster for proper alignment and improved handling. They are constructed using only the best materials while still keeping them at a competitive price. We use .120 wall chromoly tubing and replace the factory ball joints with 1” stainless steel uniballs linned with Teflon to help prevent noise. Unlike other companies we fully assemble our arms and include detailed instructions making installation quick and easy.
