ARRMA Kraton 8S BLX Heavy-Duty Front Knuckles, Oversized Bearing Upgrade - MAKX021/V1 by GPM  [MAKX021/V1]

Compact overview of the front knuckle kit

This alloy front steering knuckle set is an RC-scale replacement part designed for ARRMA 1/5 Kraton/Outcast 8S BLX platforms. Machined from 6061-T6 aluminium, the knuckles accept larger bearings than stock to increase contact surface and bearing preload options. Front hub nuts are aluminium 7075-T6 with an anti-loosening fastening detail using supplied 3x6 round head screws to keep the hub secure under heavy loads.

Installation notes: the knuckles provide three tie-rod mounting positions to tune steering roll and Ackermann characteristics without changing the steering linkage geometry. Bearings supplied are oversized relative to the original parts, so verify fit and orientation during assembly and check clearance with the brake and wheel hub components.

Tuning role: using stiffer alloy knuckles and larger inner/outer bearings can reduce deflection and improve steering consistency under high torque and rough terrain, making this a common upgrade for drivers seeking firmer front-end response.

Opt for this knuckle set when you want stronger 6061-T6 aluminium components and bigger bearing support to withstand high torque runs; always confirm clearance and torque during installation.
