GPM Racing Medium Carbon Steel+Aluminium 7075 Front/Middle/Rear Diff Case for Losi Team Losi 1/8 LMT 4WD Solid Axle Monster Truck (LMT011)

Precision diff housing engineered for LOSI LMT

This replacement differential housing is engineered for LOSI LMT solid axle monster truck configurations and is intended to locate and protect the internal bevel gears in the front, centre and rear assemblies. The outer shell is medium carbon steel for improved strength and wear resistance, while the central segment is 7075 aluminium to reduce rotating mass where the unit interfaces with the axle assembly. A rubber sealing ring is supplied to enhance oil and dirt sealing around the case.

From a setup and tuning perspective the housing maintains correct gear mesh, improves alignment stability under torque, and provides a firmer mounting surface than stock plastic housings. The increased structural stiffness supports consistent gear behaviour during high-load runs and reduces movement that can lead to premature gear wear.

Assembly notes for technicians: the kit includes all required Grade 12.9 fasteners and aluminium shims to install the housing and refit internal gears. After assembly verify gear lash and bearing endplay, and use the supplied aluminium shims to adjust mesh and preload to specification.

Packing includes

• Diff case - 1pcs
• Grade 12.9 black flat head screw 3x8 - 8pcs
• Rubber sealing ring - 1pcs
• Aluminium shim - 4pcs

Use this precision-machined aluminium-steel diff case when a direct-fit upgrade is needed to increase structural integrity and sealing for LOSI LMT solid axle differentials; confirm mesh and bearing clearances during reassembly.

What mounting checks are recommended after fitting?

Verify gear mesh using a suitable gear pattern method, check bearing endplay and axial float, and use the included aluminium shims to achieve correct mesh and preload tolerances.

How does material choice affect performance?

The medium carbon steel outer shell increases impact and wear resistance while the 7075 aluminium centre lowers rotating inertia at the axle interface, improving both durability and transient response.

Are all necessary hardware items supplied?

Yes. The package contains the diff case, eight Grade 12.9 black flat head screws 3x8, a rubber sealing ring and four aluminium shims for correct assembly and setup.

Any recommended maintenance after installation?

Periodically inspect seals, check for play in bearings and verify gear mesh under load cycles. Replace seals or shims if wear or loosening is observed to maintain service life. Write Product Review Please sign in your account before you can write any review. Sign In Close
