A machined titanium turnbuckle kit for MBX8 owners that combines a beefy 5mm square body, finned styling, standardized threads, and a matching 3mm steering drag link. Wrench sold separately.
Fin turnbuckle sets use machined Grade titanium components with a 5mm square center that tapers to a standardized thread base to accept existing rod ends.
# What was released
JConcepts introduced the Fin turnbuckle sets built specifically for the Mugen MBX8. The kit pairs a distinct visual design with machined titanium construction aimed at owners who want both an upgrade in component material and a matched aesthetic across camber and steering links.
# Design and construction
The core of the design is a 5mm square titanium section used for the camber and steering turnbuckles. That square body gradually tapers into a threaded base that accepts standard rod ends, letting the kit work with existing hardware rather than forcing new ball-ends or link types.
# What's in the set
A JConcepts turnbuckle adjustment wrench is not included and is listed separately as part number 2508.
# Fit and compatibility
The kit uses a standardized thread base so the turnbuckles are compatible with existing rod ends on MBX8 setups. That means you can swap in these titanium pieces without changing mating hardware, assuming your vehicle uses the same thread standard called out by JConcepts.
# Performance and practical trade-offs
Titanium provides a favorable strength-to-weight ratio compared with steel hardware, so these turnbuckles are marketed as lightweight while still being durable. The company frames the parts as both functional and aesthetic "jewelry," indicating the product targets users who care about finish and visual cohesion as much as component performance.
# Purchase notes and availability
The announcement came as a JConcepts press release posted on LiveRC on September 22, 2026. Colors are blue or black. The adjustment wrench required to tighten or turn these pieces is sold separately (part #2508). The press release positions this product as a bolt-on upgrade for MBX8 owners who want titanium hardware with coordinated styling.
