Kyosho RB7.5 & ZX7.5 DC13 Shock Plastic Parts Set - W5312-01

Dial out sloppy suspension play and keep your 13mm big bore dampers working buttery smooth with the factory-spec Kyosho DC13 Shock Plastic Parts Set.

When you are chasing tenths on the clock with your Ultima RB7.5 or carving high-bite lines with the Lazer ZX7.5, your damper package makes or breaks your lap times. Harsh jump landings, curb strikes, and race wear stretch lower rod ends and deform spring perches over time, introducing unwanted slop and inconsistent damping that will unsettle your chassis over washboard sections.

Molded from Kyosho’s high-precision composite nylon, the DC13 Shock Plastic Parts Set restores factory-tight ball fitment and true shock shaft alignment. Whether you are performing a mid-season rebuild to eliminate chassis chatter or stocking your pit box with race-day insurance, this genuine parts tree delivers the exact tolerances required to keep your buggy tracking straight and soaking up big landings.

Why You'll Love It

• Factory-Spec Fitment: Eliminates bind and excess play at the pivot balls and shafts for silky-smooth, predictable suspension response.
• Multiple Cup Offsets: Includes standard and offset lower spring retainers to fine-tune ride height, preload, and spring clearance without adding unnecessary collar tension.
• Durable Race Composite: Formulated to resist impact deflection and withstand violent bottoming out without cracking or popping off the pivot balls.
• Essential Pit Insurance: Provides critical replacement shock caps, eyelets, and internal cartridge spacers so a broken rod end never ends your race day early.

What's In The Box

• (1) Kyosho DC13 Shock Plastic Parts Tree (Includes Upper Shock Caps, Rod Ends/Eyelets, Lower Spring Cups, and Internal Cartridge Guide Spacers)

Note: Requires shock disassembly and fresh silicone damper oil for complete installation (sold separately). Pro-Tip: Always snip components from the sprue tree using sharp flush cutters and shave off residual gate flash flush with a hobby knife. Mold burrs on the lower spring cups can rub threaded aluminum shock bodies, and burrs on internal cartridge spacers will introduce unwanted friction and shaft drag.
