RCD Thumper I 6.0 HPOP
The Thumper I works great from stock up to 225CC injectors. This pump comes with a One Year Warranty. This pump netted and additional 100rwhp* over a new stock pump at 3000 RPM with 225CC Injectors. This is the ultimate drop in upgrade for a 2004.5-2007 Ford 6.0L Power Stroke, and will out perform any pump on the market.
