www.pr-rc.com

PR Racing introduces the SB401 10th scale Competition off road Buggy Pro Kit.
Front suspension is equipped advanced steering block and upright to improve
steering reaction and fluency, carbon fiber front and rear shock tower plate provide
durability and suspension rigidity. Kit contains strengthened parts and various
allocation to achieve the biggest track applicability.
This all new off road Buggy comes with Weight bias changeable design,
by using either the front motor configuration with a saddle pack or the rear motor
configuration with a shorty pack(All parts in one Kit). This allows the SB401 extremely
adaptable to any track condition.
PR Racing’s shock absorber always comes with quality and good design.
With a bore of 12.75mm the PR Racing Shocks is the biggest competition level
shocks in the market at this time.
Rear shock can be set to two location(in front of rear sus-arm or at rear).
With different setting, rear shock will provide enhanced driving sense and stability.
This function also allows the vehicle to soak up a wide variety for terrains and track
surfaces without losing speed. PR Racing offers a wide range (4 variations) of shock
pistons, these allow drivers to fine tune the damping
of the vehicle according track condition.
SB401 is equipped CNC bevel & drive pinion gear(39T/15T) both in front and
rear differential, those CNC gears are durable, heavy duty and works well. Differential
Gear Case whether in front or rear end, can be disassembled quickly
and easy to maintain or change.
Quality can be found throughout in the SB401 kit. All parts in the kits is made from
composites or aluminum materials. The SB401 Chassis is produced with high grade
CNC Hard anodized aluminum.
