This GPM fender vent set is engineered to enhance scale accuracy on the Traxxas TRX-4 Defender while maintaining service durability. The kit targets model builders who prioritise quality materials and practical fitment for crawler applications.
The 18-piece assembly uses injection moulded ABS components combined with bendable stainless steel vent inserts to deliver a balance of dimensional stability and impact-tolerant detail. ABS parts provide a consistent surface ready for paint or trim, while the stainless vents retain shape after minor bends and recover from low-energy impacts.
