While strength is great – the factory mounts work as intended. When you put damaging shock loads into the system from bottoming out your shock, they fail as they should instead of ripping your inside wheel wells apart. Due to OE stock mounts failing because of improper shock travel in many systems out there, BMR decided to work up a shock mount kit that improves bump travel availability. So not only do you eliminate the rubber on the stock system, but you also gain shock travel. For most lowered cars out there, your rear shocks will have the STOCK SHOCK TRAVEL when you use these new BMR-SM760 Mounts. This industry first design features an FK Bearing Co. Teflon Lined Rod-End that threads on to your stock, Ford Performance or Viking Shock. To secure it, you place the BMR Stainless Steel bump stop shoulder on to your shock, thread your jam nut down and then the rod-end. O-Rings are included with the kit to eliminate NVH increase and also help seal the bearing.
