The BAKER GrudgeBox Overdrive 6-Speed

Our GrudgeBox was designed for big engine applications and engineered with a focus on excessive torque capacity and crisp shifting. The power-robbing nature of the stock helical gears (left, above) were replaced with straight-cut spur gears (right, above) for minimal parasitic losses associated with gear-to-gear torque transfer. Circumferential tooth thickness is 100% thicker than stock and the width is 40% thicker than stock for no excuses on strength and durability. Fits 2006-2017 Dyna, 2007-up Softail & Touring.

Bagger Racing

Racing season is just around the corner with the first race in the MotoAmerica King of the Baggers Championship series scheduled for March 10-12 at Daytona International Speedway. Our longtime customer and industry leader Trask performance finished 1st in the final race of the Bagger Racing League Battle of the Baggers 2021 season last December at Sonoma Raceway.

It’s no small feat to build a bagger that will earn you a place on the podium, the people at Trask are masters at this. They took a 2017 Road Glide, completely rebuilt the engine and installed their turbo system. With their race bike producing 210hp and 190tq after these upgrades they turned to us for a GrudgeBox 6-Speed Overdrive transmission. The wider ratio of the GrudgeBox helps apply all the power in all the right places on the track. We are looking forward to seeing what they’ll do in Daytona next weekend!

Shifter Pawl Adjustment & Tricks of the Trade

Adjusting the shifter pawl is standard procedure for setting up any 1980-2000 Big Twin 5-speed transmission. Specifically, this adjustment centers the shift lever "throw" equally between the upshifts and downshifts. In 2000-2001, Harley eliminated the adjustment by replacing the PN 33119-79B eccentric adjusting screw with a fixed centering pin, PN 34978-00.

So here's the trick...if you own a 2000-2006 Softail, 2001-2005 Dyna, or a 2001-2006 Touring model, you can retrofit your stock PN 34978-00 centering pin with an eccentric adjusting screw (PN 33119-79B) and a 7/16"-14 jam nut (PN 7515). This will allow you to dial in your shift throws and make your bike upshift and downshift like greased lightning.
