Team Associated SC10 4x4 Ceramic Ball Bearing Kit
Regular price $169.99 Sale price $74.99 Save $95.00Choose "Shop Pay" at checkout to pay in 4 easy interest free installments!
Team Associated did it again with the SC10 4x4 Short Course truck. Some new features which are striking are a unique dual gearbox drive train coupled together with a 5mm heavy duty belt system with external tension adjustment, 32 pitch front and rear gearboxes with sealed fluid filled differentials which is something we normally see in 1:8 scale buggies but is becoming increasingly popular, decoupled center slipper clutch allows for front and rear wheel drive to slip independently, resulting in more traction and stability on bumpy track conditions, and CVAs with captured drive pins and heavy duty 6mm alloy axles.
What we particularly like is the use of beefy MR126 and 6701 size bearings which are the 6x12x4mm ball bearings and 12x18x4mm ball bearings that can withstant greater abuse than the traditional 3/16x3/8 bearings. A short course truck of this performance level needed a redesign in the bearing department to accomodate the increase in pressure. The new bigger size does the trick but take it to another level of performance, speed, and durability with our ceramic bearing kit. We include everything you see here which includes the special 5x10x3mm ceramic ball bearings.

Savage XL Ceramic Bearing Kit
Regular price $89.99Choose "Shop Pay" at checkout to pay in 4 easy interest free installments!
To get the long wheelbase of the Savage XL, HPI Racing's team of talented designers developed an all-new extended TVP (Twin Vertical Plate) chassis made from 3mm thick 6061 aluminum. 6061-series aluminum is light and strong and provides the strength for stretching the Savage platform to its limits. The chassis has Savage XL logos etched into the chassis to really make it stand out. The engine is fitted to a one piece engine mount with an extra-thick 3mm engine mounting plate. These are the thickest TVP and engine plate parts ever offered on a Savage monster truck, giving the Savage XL the strength to withstand the enormous torque of the massive Nitro Star K5.9 engine.
ACER Racing's World Champion rc bearing kit for the HPI Savage XL is designed to withstand the massive torque displaced by the K5.9 engine.
