Description:Our strong tubular steel construction adjustable control arms are the perfect upgrade to the factory stamped steel control arms. Including heavy wall DOM sleeves and collars, TIG welded 4140 Chromoly fine thread shanks, custom-designed Daystar brand PTMEG poly bushings, and pre-installed zerk fittings, these arms come completely ready to install - Just remove your factory arms and bolt these right in!Our heavy wall DOM sleeves are application specific, and guaranteed to perfectly fit your year model truck (year models have different sizes of hardware, requiring different inner diameter sleeves for optimal fitment). Cheaper rolled sleeves with a seem can split apart, due to stress from movement (see comparison images), shredding your bushings from within!These adjustable arms also feature 4140 Chromoly fine thread shanks! This material is SAFE TO WELD. While other manufacturers are content to use any old "all thread" material to make their shanks, we did the research to find the best, and SAFEST, material to use for our adjustable arms! Welding changes the composition of metal, and most "all thread" material is NOT considered safe to weld due to these compositional changes. Our shanks are machined, not cast/formed, so welding them is perfectly safe, while the fine thread allows for precise adjustability. Additionally, these shanks are TIG welded to our DOM collars for ultimate strength!Kit Contents:(2) Adjustable Upper Control Arms(2) Adjustable Lower Control Arms(2) Stryker DecalsFitment:03-09 Dodge Ram 2500/3500 4WD with 1" to 6" of lift depending on the model you choose.Technical Notes:Also fits all Mega Cab models; Re-uses factory hardware
