**This package includes 4 pistons, the rear pistons are pre-drilled 2 holes larger @ 1.60mm which was the best during our 2021 testing.**
The Schelle bevel piston design is a simple concept to give the bump (compression) performance of a flat piston, yet accelerate the extension (rebound) stroke slightly by improving the flow with a bevel around the outer edge of the piston. The 5x1.5 base valving was updated in 2021 over months of testing and is ideal for hard bladder (waffle style like RC8B3.2) shock packages on outdoor and indoor temporary tracks or when you want initial softness and less progression (pack) initially. For the rear suspension, we pre-drill the Pro-Built set with 2 holes 1.60mm, but for lower grip conditions we recommend drilling out a 3rd hole 1.60mm.
Updated in 2021 for hard bladder shocks. What you'll notice on the track is the buggy is more plush on landings, less suspension flutter (especially in hot weather) due to the O.D. fit. The faster rebound helps keep the tires planted and won't hop on landings.

"I used the pistons today at the track with your recommended oils and my car was about 1/2 second faster around the track. The car was more plush with more traction. Thanks for the awesome product." -Tim F. (MakinTraxx RC, New York) Conditions: Track was dry and bumpy with a loamy outside.
