Our GeoPro G19RD has a tongue weight of ~420lbs. When the truck bed is loaded for a RV trip, the weight of cargo plus the GeoPro causes hitch sag. There are a variety of solutions to improve the truck’s rear suspension but Sumo Springs are easy to install and simple. I opted for the black ‘1,800lb’ version There are two others colors: blue = ‘1400lb’ light-medium duty; and yellow = medium-heavy duty (not designed for the Tacoma). For everyday driving & light duty, the blue would typically replace the stock bump stops. But if you tow a trailer, the black higher density is better at reducing hitch sag.

I installed the Sumo Springs using a socket wrench to remove the nuts holding the bump stop u-brackets. Tip: turns out you do not need to completely remove the u-brackets, just loosen, since the stops only need 1/2″ of foot clearance to be removed. The Sumo Springs replace the (surprisingly small) stock Toyota bump stops. I did not need to jack my 2020 Tacoma TRD Off-Road 4×4 up since there was enough clearance. I did the installation on level ground with tire blocks to insure the truck didn’t roll over me.

Since the hitch will dip ~1″ before contacting the Sumo Springs, the difference isn’t clearly perceptible in the sideview photos. But I did see a difference in the rear fender clearance of Tacoma when loaded & hitched to the GeoPro. Plus the tow ride has definitely improved with much less ‘porpoising’ and less overall tail bounce. It is a firmer ride but since there’s less bounce, it’s a worthwhile improvement.
