Overview
The ARRMA Limited Slip Diff Plates for 29mm Diff Case are essential replacement parts designed for ARRMA RC vehicles. Whether you're running an ARRMA 1/8 scale Kraton, Notorious, Talion or Outcast, or a 1/7 scale Limitless or Mojave, these precision-engineered diff plates are the ideal solution for maintaining optimal drivetrain performance. If you've noticed your RC car is 'diffing out' during cornering or acceleration, these limited slip diff plates will restore the traction and control you need for consistent handling on track or off-road terrain. Built to exacting standards from high-quality stainless steel, these plates provide the friction needed to prevent wheel spin and improve overall vehicle dynamics.
Limited slip differentials are crucial components in any high-performance RC car, 4x4 RC truck or competitive RC buggy. When a standard diff allows one wheel to spin freely whilst the other loses grip, your vehicle becomes unpredictable and slower. By increasing friction between the gears and the diff case, ARRMA's limited slip diff plates solve this problem, delivering a balanced power delivery to both wheels. This is particularly important for UK RC enthusiasts who bash or race on variable terrain where consistent traction is paramount.
These diff plates are supplied as a complete set for one differential, making them the perfect upgrade or maintenance replacement for your ARRMA RC model. Available now at RC Model Shop, they're in stock and ready to ship to RC hobbyists across the UK.
Key Features
- Precision Stamped Stainless Steel Construction — Each diff plate is precision stamped from high-quality stainless steel, ensuring exceptional durability and resistance to corrosion, which extends the lifespan of your drivetrain components and maintains performance over many seasons of use.
- Limited Slip Action — The plates provide increased friction between the gears and the diff case, creating a limited slip action that prevents 'diffing out' and ensures both wheels receive consistent power delivery, dramatically improving traction and cornering performance.
- Prevents Wheel Spin — By reducing differential action during acceleration and cornering, these plates eliminate the frustrating wheel spin that often plagues standard open differentials, giving you better control and faster lap times whether you're racing or bashing.
- Complete Set for One Diff — This package includes everything you need to service or upgrade a single 29mm diff case: 2 x Limited Diff Plate A, 4 x Limited Diff Plate B, and 4 x Limited Diff Plate C, ensuring you have the correct assortment of plate thicknesses for optimal friction tuning.
- Compatible with 29mm Diff Case — Designed specifically for ARRMA vehicles fitted with 29mm differential cases, these plates are a direct replacement and are listed as standard parts for numerous ARRMA models including Kraton, Outcast, Talion, Limitless and Mojave variants.
Technical Performance
The ARRMA Limited Slip Diff Plates are engineered to deliver measurable improvements in drivetrain performance across a wide range of ARRMA RC vehicles. Manufactured from high-quality stainless steel and precision stamped to exact tolerances, these plates work by increasing the frictional contact between the gears and the differential case housing. This frictional increase is what creates the 'limited slip' effect, where the differential gradually transfers more torque to the wheel with better traction as the speed differential between wheels increases. The set includes multiple plate types — Plate A (2 pieces), Plate B (4 pieces), and Plate C (4 pieces) — allowing you to fine-tune the amount of slip based on your driving conditions and preferences. The stainless steel material ensures longevity and resistance to the wear that comes from repeated use in muddy, wet, or sandy terrain common to UK RC bashers and racers. These plates are manufactured to work seamlessly with 29mm diff case differentials found across ARRMA's extensive 1/8 and 1/7 scale lineup, from high-performance speed trucks like the Kraton and Talion to aggressive stunt trucks like the Outcast and Notorious, as well as the premium 1/7 scale models including the Limitless and Mojave.

Frequently Asked Questions
- What does a limited slip differential do in an RC car? — A limited slip differential reduces the difference in wheel speed between the inside and outside wheels during cornering and acceleration. Standard open diffs allow one wheel to spin freely whilst the other loses grip, causing unpredictable handling and slower cornering speeds. Limited slip diffs use friction plates to gradually increase torque delivery to the wheel with better traction, resulting in more consistent power delivery, improved traction, faster lap times and better overall vehicle control whether you're racing a track or bashing off-road terrain.
- Will these diff plates fit my ARRMA RC car? — These limited slip diff plates are designed specifically for ARRMA vehicles equipped with 29mm differential cases. They are listed as standard parts for numerous ARRMA models including the 1/8 scale Kraton, Notorious, Talion, and Outcast, as well as 1/7 scale models like the Limitless and Mojave. Check your vehicle's specification or contact RC Model Shop if you're unsure whether your particular ARRMA model uses a 29mm diff case.
- Why would I need to replace my diff plates? — Over time, repeated use causes wear to the friction surfaces of diff plates, reducing their effectiveness in creating limited slip action. Additionally, if you've been running your RC car with an open differential and are experiencing excessive wheel spin or poor traction, upgrading to or reinstalling limited slip diff plates can dramatically improve performance. These replacement plates allow you to restore or upgrade your differential's performance characteristics.
- Are these difficult to install? — Installation requires disassembly of your differential case, which involves removing the diff from your RC car and carefully separating the housing. If you're familiar with basic RC car maintenance and have the proper tools, installation is straightforward. However, if you're new to RC cars and unsure about differential work, many UK RC hobby shops offer assembly services. Always consult your ARRMA vehicle's manual for specific disassembly and reassembly instructions, and ensure you use proper differential lubricant when reassembling.
- What's the difference between Plate A, Plate B and Plate C? — The different plate types vary in thickness or material composition, which affects the amount of friction created within the differential. The assortment of 2 x Plate A, 4 x Plate B, and 4 x Plate C provides the correct configuration for optimal limited slip action in a 29mm ARRMA diff case. The specific arrangement of these different plate types creates the desired friction characteristics that prevent wheel spin whilst still allowing necessary differential action during cornering.
- Can I use these on any RC vehicle? — No, these plates are specifically designed for ARRMA vehicles with 29mm differential cases. They are not compatible with other brands or ARRMA models that use different diff case sizes. Always verify your vehicle's differential specifications before purchasing.
- How long do diff plates last? — The lifespan of diff plates depends on usage frequency, terrain type, and driving style. Stainless steel plates like these are highly durable and resist corrosion, making them long-lasting. However, the friction surfaces gradually wear with use, which is why replacement sets are essential maintenance items for serious RC enthusiasts. Regular inspection and replacement as needed will keep your drivetrain performing at peak efficiency.
