left-right transitions
- Motor
mount bulkhead is combined with layshaft bulkhead in 1 solid piece to
eliminate tweak caused by connected screws
- Motor
mount bulkhead is connected with alu motor mount plate to eliminate tweak,
also offers multiple flex adjustment possibilities by adding/removing
screw ahead or behind the nut, or by using optional post instead of the
nut
- The
motor mount plate is connected to the chassis via an M3 nut and an extra
countersunk screw can be placed ahead or behind the nut if more
reinforcement is needed, or the nut can be removed and 1 or more of 6
holes can be used as extra flex adjustment options
- Front
& rear lower bulkheads accommodate the anti-roll bar bearing mounting
system
Suspension
- Kit
includes both standard & ARS™ (Active Rear Suspension™) rear
suspensions
- ARS™
suspension offers great adjustment possibilities and driving
characteristics
- ARS™
suspension consists of ARS™ arms, graphite 0° C-hubs for optimal flex
characteristics, hard suspension block, ARS™ suspension block, and ARS™
linkage connecting the holder to the suspension block
- ARS™
linkage angle – adjusted by adding/removing shims on the steering block
and ARS™-holder – changes the toe-in characteristics of the rear tires
during chassis roll
- Aluminum
suspension holders featuring Integrated Suspension Settings (ISS) for
quick & easy suspension geometry adjustment
- Suspension
holders allow more durable mounting of the suspension arms, so the
suspension geometry of the car does not change even after hard crashes
- Suspension
mounting system allows for very free arm movement, which gives higher
traction, smoother driving, and improved steering
- Suspension
holder system allows suspension arms to be mounted independently from
bulkheads allowing for elongated chassis flex to generate more traction
- Independent
suspension holders allow for more precise and fine set-up adjustments via
different bushings
- Rear
suspension aluminum holders feature integrated toe-in
- C-hubs
available optionally in standard caster angles (0°, 2°, 4°, 6°); available
in four hardnesses (M – medium, H – hard, G – graphite and aluminum)
- Hard
front steering blocks increase steering response, decrease front tire
overheating in high-traction conditions
- Small,
robust steering blocks made from special proprietary composite material,
available optionally in 3 hardnesses (M – medium, H – hard, G – graphite
and aluminum), and feature 2 Ackermann positions
- Rear
uprights give increased stability; available optionally in 3 hardnesses (M
– medium, H – hard, G - graphite)
- Rear
uprights feature integrated 0° toe-in to prevent suspension geometry
changes in serious crashes
- Arms
feature innovative SFATM (Suspension Flex Adjustment), innovative and
unique graphite stiffeners allow for super-quick suspension flex
adjustment to easily adjust the traction of the car under various track
conditions
- Suspension
arms feature integrated anti-roll bar mounts; rear arms feature 3
different anti-roll bar mounts for super-fine adjustment of the rear
anti-roll bar
- Suspension
arms made from graphite material for improved traction and stability of
the car
- Anti-roll
bar system is mounted to the bulkheads via bearings for extra-smooth
movement and maximum precision, and side play is eliminated by aluminum
bushings
- Anti-roll
bar height is adjustable via simple screw adjustment… quick & easy
- Front
1.4 mm & rear 1.3mm anti-roll bar wires included
- Easily-adjustable
wheel offset using optional wheel hubs (-0.75mm, +0.75mm, +1.5mm)
Drivetrain
- Lightweight
middle layshaft CNC-machined from aircraft aluminum
- 84T
48P spur gear – extra-hard material, wobble-free design
- 38/20T
(1.9) internal gearing for efficient, high-performance drivetrain
- Premium-quality drive
belts
- C-hubs
with large openings for quick & easy assembly/disassembly of the CVDs
and ECS drive shafts; prevents collision of CVD or ECS drive shafts with C‑hub
in serious crashes
- Super-light
drive axles
- Front
Extra-Strong ECS drive shafts equalize the speed between the drive shaft
and the wheel. With a unique 2-piece joint between the axle and the wheel,
any extreme wheel turning angle is divided into two shallower angles
without joint binding. This means that regardless of the cornering speed
and wheel angle, the inner wheel will not bind or vibrate. Drive through
corners is more stable, more precise, and easier to drive
- ECS
drive shafts made from world-renowned, self-developed HUDY Spring Steel™;
hand ground for maximum precision
- Super-lightweight
Swiss 7075 T6 aluminum rear drive shafts (50mm), hard-anodized,
color-coated and laser-engraved, 38% lighter than standard drive shafts
- Super-lightweight
wheel axles manufactured from premium HUDY Spring Steel™
- 7075
T6 aluminum wheel hubs
- Complete
set of high-speed, blue-sealed ball-bearings are degreased and lightly
oiled for maximum efficiency, individually controlled, selected, and
inspected

self-locking wheel nuts
Differentials
- Super-smooth,
super-light maintenance-free composite gear differential
- Adjustable
gear differential stiffness via oil viscosity
- Super-light
composite Front Solid Axle with XRAY’s own smart quick-change outdrive
system for easy outdrive exchange; no servicing or replacement of drive
shaft blades needed, translates into reduced servicing costs
Steering
- Servo
mounting system for improved balance and elimination of unwanted tweak
- Servo
mount allows the servo to be suspended into the chassis centerline,
providing better balance while eliminating tweak and allowing for
additional traction
-
- Steering
is isolated from chassis flex, ensuring tweak-independent steering for
super-precise and consistent steering characteristics
- Servo
mount and graphite servo holder are mounted to the chassis with 3 screws
and 2 centering posts to eliminate the possibility of servo movement under
hard crashes
- Servo
mount includes extra hole where the battery backstop screw can be mounted
- Servo
mount includes extra hole for in-line flex adjustment system
Shocks
- Ultra-
Low Profile (ULP) aluminum shocks for even lower CG and improved stability
- ULP
aluminum shocks have been shortened by 4mm comparing to SLP shocks
to provide maximum stability under all track conditions, while reducing
traction roll under high-traction conditions and to make the car easier to
drive
- Shock
shafts are specially hardened for maximum strength
- Foam
inserts for perfect shock rebound
- Super
Short Shock Springs (4S) developed & designed for the SLP shocks
- C2.5
springs included in the kit to fit ULP shocks and the spring rates have
been optimized to provide maximum steering and traction
- XRAY
self-developed and manufactured 4S springs are manually selected for
maximum precision, equal length, and equal damping characteristics
- Race-tested
and tuned shock positions
