Constructed with alpha chromoly ball joints, CNC-machined bushings and housings, and PU pivot bushings, the kit is supplied complete with hardware and arrives ready for installation. These arms are designed for both 4WD and RWD applications on 6-lug hubs and require a post-installation alignment to ensure correct suspension geometry.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these control arms improve ride and durability?\u003c\/h3\u003e\n\u003cp\u003eThe BST BSSP arms use higher-strength materials and refined bushings to reduce deflection and extend service life compared with factory control arms. The whole PU bushings resist deterioration from oil and road contaminants better than rubber. A tower-style dust cover protects the joint in extreme temperatures and rough environments.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAlpha chromoly ball joints with built-in taper for secure fitment\u003c\/li\u003e\n  \u003cli\u003eFull polyurethane pivot bushings for improved responsiveness\u003c\/li\u003e\n  \u003cli\u003eTower-type dust covers for longer joint life\u003c\/li\u003e\n  \u003cli\u003eCNC-machined components and precision welding for strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does installation involve and what’s included?\u003c\/h3\u003e\n\u003cp\u003eThe kit is 100% bolt-on and comes as a matched pair with all necessary hardware shown in the product photos, simplifying swap-out of worn or damaged OEM arms. Ball joints and bushings are pre-installed on the control arms; however, avoid using excessive force on the copper zerk fittings during maintenance.
