Molded holders for lower suspension pivot pins. Set of four. 

Set of molded composite lower suspension pin holders. The suspension holders have a 0.75mm eccentric hole that lowers the rear roll center. Using the eccentric rear suspension holders will create more rear grip and at the same time increase steering.  

CNC-machined alu brace that aligns and supports the molded lower suspension holders. 

Set of nylon hubs includes: four eccentric hubs for differential ball-bearings, two non-eccentric hubs for layshaft ball-bearings. Eccentric hubs allow for tightening and loosening of front and rear drive belts. 

Machined alu brace that supports the rear bulkheads. 

Complete ball-differential set uses new special Swiss 7075 T6 aluminum which is 30% stronger than previous material. Features heat-treated and hardcoated aluminum output shafts, screw for external adjustment, tough composite 34T diff pulley with Labyrinth Dust Covers™, high-performance ball-bearings, high-quality carbide axial thrustbearing, heavy-duty diff washers, and carbide diff balls. Factory pre-assembled. 

XRAY is proud to present the smoothest, highest-quality differential in the RC industry! Manufactured exclusively for XRAY by HUDY, made from world-renowned top-secret Hudy Spring Steel, this high-performance differential set features an exclusive double slotted design, carbide diff balls, new axial ball-bearing with larger balls for smoother operation and ultra-high durability.

Ultra-Flex High-Performance Drive Belt
For top competition racing XRAY offers these specially modified high-performance drive belts. The belts are very thin and elastic as possible to create much more effective transmissions, save batteries and eliminate friction. The belt is specially modified - hand ground on a special machine so the belt is as thin as possible, but in such a way that it will still have long life.
"A must have item for serious racers."

"A must have item for serious racers." 

Specially modified high-performance 3mm-wide drive belt is 1mm narrower than original 4mm belt (#305441) for increased transmission efficiency. This belt is very thin and elastic as possible for an extremely effective transmission that saves batteries and eliminates friction. The belt is specially modified - hand ground on a special machine so the belt is as thin as possible, but in such a way that it will still have long life.

To fully enjoy the benefits from these high-performance belts, be sure all the transmission's ball-bearings are absolutely clean and there is no undue drag or friction. 

Solid central layshaft set for use when you do not use the one-way action of the original central layshaft, and is especially useful when using the front one-way differential. 

Central layshaft with press-fit adapter. The layshaft is manufactured exclusively by HUDY from world-renowned top-secret "Hudy Spring Steel". The hollow layshaft construction provides ultra low weight and low rotating mass. The adapter is accurately pressed directly onto the layshaft to give ultra-true spur gear rotation. 

Molded nut for adjustment of one-way pulley. 

New high-performance option set of low ratio pulleys. The set includes 32T front and rear differential pulleys and Labyrinth Dust Covers (TM), 32T pulley for front one-way, and 18T central layshaft pulleys.  

Molded 16T pulley that is fixed to the central layshaft. 

Precision molded composite "low ratio" pulleys (18T) and side plate for use on solid central layshaft. Set of 2 pulleys and 1 side plate. The teeth number (18) is embossed into the side of each pulley for easy identification. 

New one-way bearing for the middle shaft. This bearing has grooves on its outer surface that will prevent any potential rotational slippage inside the nylon pulley.
