Yes. The Stump Puller is one of the best A.P.E. packages for Touring Harleys like the Road Glide, Street Glide, Road King and Ultra. Its torque focus makes carrying a passenger or luggage, climbing hills and overtaking at highway speeds noticeably easier.
Yes. The Stump Puller is designed to work with stock Milwaukee-Eight cylinder heads, which keeps costs down while still delivering a major torque increase. Riders who want more top-end power can look at ported-head packages like the Sneaky Pete or Silverback.
A.P.E. Stump Puller packages at Taverner Motorsports start from $6,840 for 124ci and $6,840 for 128ci, supplied and installed, including dyno tuning. The final price depends on your model, cam choice and any extra parts. Request a quote for a fixed price.
Note: $6,840 represents the installed & dyno-tuned baseline for both 124ci and 128ci packages. If referencing parts-only hardware direct from A.P.E., both start from $4,190.
As a guide, a 124ci Stump Puller makes around 145–150+ ft-lb and a 128ci makes around 150–155+ ft-lb with the right exhaust, intake and tune. See our dyno results for real figures from bikes we've built.
Some 2017-2019 M8 models may require an upgraded MY20 eight-lobe scavenge oil pump when installing Stump Puller packages. This should be confirmed during the build planning stage.
Yes. Dyno tuning is recommended to optimise fuel delivery, ignition timing and safe performance.
The Stump Puller suits Milwaukee-Eight Touring models (Road Glide, Street Glide, Road King, Ultra) and Softails such as the Fat Boy and Breakout. 107ci engines go to 124ci, and 114ci and 117ci engines go to 128ci. Contact us to confirm fitment for your model and year.
