GPM Racing 7075 Alloy Front Spindle Set (Larger Inner Bearings) for Losi Team Losi 1/8 LMT 4WD Solid Axle Monster Truck (LMT021N)

Technical role of the front spindle assembly

This front spindle set is a precision aftermarket replacement for LOSI LMT solid axle 1/8 monster truck platforms. CNC-machined from 7075 alloy and supplied with larger 6x15x5 inner bearings, the component focuses on accurate bearing seating and reducing eccentric CVD rotation under high-load or high-RPM conditions. The assembly reduces interface play at the CVD to hub junction to preserve steering input fidelity.

The kit ships with the standard mounting hardware required for direct replacement on the listed LOSI models, and the bearing footprint is engineered for enlarged 6x15x5mm bearings included in the package to ensure concentric rotation. The design is concentrated on precision fit and bearing location rather than cosmetic alterations, delivering a robust hop-up for chassis tuning and long-term durability in hobby operation.

Engineered as a precision hop-up, this GPM front spindle set replaces the factory hub with a CNC 7075 alloy assembly and larger 6x15x5 bearings to minimise play and ensure concentric CVD rotation, offering measurable improvements in steering consistency and driveline stability for LOSI LMT models.

What tolerance and material improvements does this spindle offer?

The spindle is machined from 7075 aluminium for higher strength-to-weight and is engineered for a 6x15x5 bearing footprint to reduce eccentricity and improve rotational concentricity at the CVD interface.

How does the bearing change affect drivetrain behaviour?

Larger inner bearings provide increased contact area and better radial stiffness, which helps maintain alignment under load and reduces CVD wobble that can introduce steering inconsistency.

Are installation tolerances documented?

The pack includes the hardware and specified bearing sizes; installers should verify seat fitment and use established fitment practices such as light press fit and correct torque for Grade 12.9 fasteners.

Intended application and operating profile?

Designed for aggressive off-road and bashing conditions as well as demanding track use, the spindle improves bearing location accuracy and driveline consistency for LOSI LMT solid axle 1/8 platforms. Write Product Review Please sign in your account before you can write any review. Sign In Close
