** Oct 2023 - Go check SCH1505 16mm Fat Boys 2.2 5 hole for the latest design and next evolution of these pistons **

**2024 update: This package includes 4 pistons, the rear pistons are pre-drilled (3x1.5, 1x1.6), Fronts are high-pack (4x1.4, 1x1.5) unless otherwise requested.**

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 5 hole base valving was updated in 2022 with high-pack fronts and 2 larger 1.6 holes rear.  This  shock package has been the best emulsion or bladder on outdoor and indoor temporary tracks or when you want initial softness and less progression (pack) initially.   Fronts are 5 holes 3x1.4mm and 2x1.5mm "high pack".  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 set in 2022 for both emulsion and hard bladders.   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.  

Hot Weather (drop oil if needed for hard bladders):
Front: 45wt AE (600 CST) 3x1.4 & 2 x 1.5
Rear: 40 wt to 42.5 wt AE  (500-550 CST) 3 x 1.50 & 2 x 1.60mm 

Cold Weather (below 60F):
Front: 42.5wt AE (550 CST) 5 x 1.50
Rear: 37.5wt AE  (450 CST) 3 x 1.50 & 2 x 1.60mm

Testimonial:

"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.
