RPM's backing plate is the foundation of their new gear cover. It bolts in place of the stock gear cover using the two stock mounting screws. The backing plate protects the chassis side of the pinion and spur gears while a series of ribs that rest against the chassis plate add significant support to the RPM gear cover. Additionally, the backing plate remains in place, even while the gear cover, spur, and pinion gears are removed during maintenance.

Three new screws and a hex nut are included with the gear cover assembly allowing the gear cover to bolt up to the RPM backing plate. The three new mounting locations provide the best possible support and helps seal the gear cover to the backing plate. The RPM gear cover has ample room to fit almost any combination of gears without clearance issues. In addition, we package our trademark soft plug in with each gear cover assembly which provides much easier access to the slipper clutch adjustment nut than the stock gear cover.

RPM LST / LST2 / Aftershock gear covers are molded in their trademark blend of indestructible nylons and are sold in either blue or black to compliment or contrast any paint or chassis color scheme.
