1RC Racing 1RC5001

This multi-rate tuning kit allows racers and hobbyists to adjust their vehicle’s handling characteristics, weight transfer, and chassis response based on changing track conditions. Providing a variety of tension options, it helps dial in cornering performance and stability on dirt ovals and carpets alike.

Key Features

• Official 1RC Racing Component: Genuine part number 1RC5001 ensures direct fitment on stock and upgraded 1RC shock assemblies.

• Comprehensive Multi-Rate Selection: Includes 12 springs split across three different stiffness levels, allowing you to mix and match setup options for front and rear dampening.

• Track Tuning Versatility: Softens or stiffens the suspension roll to combat traction loss, looseness, or excessive body lean.

Kit Contents (12-Pack)

• (4) Soft Springs (Black): Offers increased weight transfer and maximum grip on low-bite or slick surfaces.

• (4) Medium Springs (Dull Silver): Serves as the standard baseline setup matching the stock springs that typically come out of the box.

• (4) Firm/Hard Springs (Bright Silver): Features a tighter coil count configuration compared to stock, offering quicker responsiveness and reduced chassis dive on high-grip tracks.

Compatibility & Tuning Tip

• Vehicle Compatibility: Designed for 1RC 1/18 scale platforms including the Midget, Midget 2.0, Sprint Car, EDM, and Late Model.

• Tuning Tip: Changing front versus rear spring rates drastically alters steering entry and exit. Try switching to softer springs on the rear to generate extra forward bite on loose dirt tracks, or firmer springs up front to quicken initial steering response.
