Thank you for viewing! We sell products created by incorporating the know-how gained from winning and placing in numerous competitions. Product Description: This is an MS chassis that has been lightweighted and flexibly processed. (Standard axle retention) By using a milling machine and minimizing the manual work, the chassis is finished with fewer product errors. The flexibility has been confirmed during production. It moves well, has high vibration damping properties, and is a chassis with good drive efficiency. Although a new chassis was processed, it is considered "like new" because it is a processed product. Springs are not included. Please use the black springs included in the AO1034 Slide Damper Spring Set. If you let me know in the comments before purchasing, I will send the spring set together for an additional 198 yen. Be sure to apply grease to the moving parts during assembly. Mix the blue and red grease from the No. 15471 HG Slide Damper Grease Set and adjust the damping force to your liking. If you let me know in the comments before purchasing, I will send the HG Slide Damper Grease Set together for an additional 440 yen. Processing Options: You can choose the flex stroke amount as long, medium, or short by special order. (Free) If not specified, it will be made with medium. (V-cut flex is basically short only. Medium or longer requires consultation) The bottom of the front and rear units, and the parts where the counter touches during movement, are intentionally not processed (because of individual preferences). I will process them for free if you let me know. Front and rear unit step-up processing is possible with a milling machine. (If the lift amount is not specified, it will be a 1.8mm lift) +800 yen (If processing either the front or rear, +500 yen) Center chassis bottom surface milling processing +1000 yen Rear bumper arch cut +500 yen Change to reinforced front and rear units No. 15367 N-02/T-01 reinforced unit +330 yen If you purchase multiple items at the same time, you will receive a 210 yen discount from the second item onwards.
