PROCRAWLER team announced the new self-developed Grind 431™ LCG OD Transmission in mid-October and pre-ordering has also begun!
Champion Proven Performance
The amazing performance of the Grind 431™ LCG OD Transmission has been tested and proven for 6 months by Team PROCRAWLER® Factory Driver Massimo “Max” Bonvini (IT).
Super Light & Super Low LCG Design
The primary goal with the Grind 431™ LCG OD Transmission was to create the lightest and lowest LCG transmission in its class.
- Net weight is 64 g.
- Net weight /w skid is 95 g.
- Housing height /wo insert hub is 31 mm.
- Motorplate height is 36 mm.
Thanks to the disciplined design and the carefully chosen high-tech materials and technologies we got there to succeed.
31% Sweet Spot Overdrive
They spent tons of wheel hours on the rocks putting our Flatgekko™ rigs in work and found 31% as the sweet spot when it comes to overdrive rate.
That’s why they designed the Grind 431™ LCG OD Transmission around this magical value and implemented 31% overdrive in it.
Lightened & Hardened Custom Steel Gears
After long months of research they haven’t found the proper gears for the Grind 431™ LCG OD Transmission so the team decided to design and manufacture the perfect gearing.
The all-new lightened gear design and the hardened steel material together make the Grind 431™ gearing super light, strong and durable while the M0.5 modulus teeth ensure ultra smooth running.
2.5mm Toray® Premium High-Grade Graphite Motorplate
When compiled the product features list of the Grind 431™ LCG OD Transmission it was not a question to use the ultimate Toray® premium high-grade graphite material for the motormount plate.
Toray® premium high-grade graphite, this high-end quality carbon is ultra light but still super strong as they already experienced at the C23 V2 chassis rails, all in all the perfect motorplate material.
Ultra Light High-Tech Nylon Polymer Housing
Crafting the lightest but still powerful LCG OD transmission in its class requires careful engineering when it comes to materials.
That’s why to use the super light and rock solid PA12 high-tech nylon polymer paired with the high-end SLS (Selective Laser Sintering) 3D printing technology for the housing of the Grind 431™ LCG OD Transmission with metal inserts for long lasting threads.
Custom Stainless Steel Shafts
Smooth running depends on several elements of a competition level LCG transmission. One of them are the properly designed and manufactured shafts.
Engineered the perfect custom stainless steel shafts for the Grind 431™ LCG OD Transmission to support its butter smooth running on a long term basis.
High-Performance & Durable Bearings
They have looked into and tested dozens of bearings until found the perfect ones for the Grind 431™ LCG OD Transmission.
The high-performance and durable oiled Grind 431™ stainless steel bearings run smooth like a breath of fresh air but are resistant to dust and mud.
Carefully Engineered Gear Ratios
Gear ratios must be carefully engineered fitting the purpose of use.
They have spent months doing the maths homework and defined the gearing of the Grind 431™ LCG OD Transmission to fit the needs of pro scale rock crawling perfectly.

Dedicated C23 V2, 6º Re-Angled & Straight Skid Options
Grind 431™ LCG OD Transmission is a seamless fit for the C23 V2 LCG Chassis System for sure but was designed to also fit any chassis rails no matter if having angled or straight skid.
That’s why the Grind 431™ is available with C23 V2, 6º re-angled and straight skid options. Feel free to take our choice!
Made In Europe
The Transmission is designed in-house by the engineering artists of Team PROCRAWLER® in Hungary/Europe.
High-quality production is processed on state-of-the-art Hungarian and Italian 3D printers and CNC machines so the Grind 431™ is crafted of the finest that the EU has.
