This complete kit includes (1) set of UMI Performance single adjustable lower control arms and (1) set of UMI’s "on-car" double adjustable upper control arms. These direct bolt-on replacements are designed to minimize wheel hop, improve cornering while lowering ET's and help track consistency. The upper control arms feature on-car adjustability, allowing quick and easy pinion angle adjustments; its as simple as loosing 2 nuts! The spherical rod end allows for a “bind free” operation, making a great upgrade for both your track and auto cross driven vehicle. The polyurethane bushings are designed to be bolted to the car chassis for a quiet comfortable operation. Lower Control arms are constructed of DOM mild steel tubing 1.500” OD x 0.120” wall, 4130 chrome moly threaded tube adaptor, completely CNC machined and fully TIG welded for outstanding strength. The upper control arms feature 0.250” mild steel mounting points, 4130 chrome moly tube adaptor and 4140 chrome moly heat treated 1.120” solid adjuster, truly overkill. Control arms feature Energy Suspension® polyurethane bushings, zinc plated steel sleeves and “on-car” grease able zerk grease fittings. Adjustments can be made using the high quality QA1® Teflon lined spherical rod ends that operate for a quiet bind free performance. Our lower control arms feature reinforced spring perches and heavy duty sway bar mounting points.
We use only high quality QA1 spherical rod ends (Part # XMR12/XML12), alloy steel, heat treated, hard chrome plated featuring Teflon/Kevlar self lubricating race. Teflon lined rod ends allow for a quiet operation not found with other brand rod ends. When purchasing rod ended components don't be fooled, use only the best, QA1 for a long lasting performance.
