GKN Motorsport Standard 94mm Plunging CV Joint

Engineered by GKN Motorsport, the global benchmark for competition driveline systems, this standard 94mm outer diameter (OD) plunging constant velocity joint is developed to survive the brutal shock loads of short-circuit and dirt oval racing. Backed by over 30 years of continuous product evolution, this component provides reliable mechanical tracking, cooler operational running temperatures, and an extended service life under demanding track conditions.

This plunging CV joint features a precision-machined 32mm body width, a 33-spline internal core design, and an 8mm bolt hole interface configuration. It permits up to +/-8mm of smooth linear plunge, making it the industry standard choice for the inboard position (transmission side) on front-wheel-drive (FWD) vehicles, as well as both the inboard and outboard positions on rear-wheel-drive (RWD) and all-wheel-drive (AWD) independent suspension setups.

Key Technical Features:

• Optimal Plunging Design: Features +/-8mm of linear axial plunge travel to effortlessly accommodate dynamic track wheel travel and suspension geometry changes without binding.

• Precision Spline Engagement: Explicitly configured with a 33 internal spline count to ensure completely slop-free torque transfer onto compatible race driveshafts.

• Cooler Operating Temperatures: Internal race and cage geometry reduces friction, mitigating extreme heat buildup under heavy load to prevent premature grease breakdown.

• Unsurpassed Reliability: Manufactured by GKN, the world's leading driveline specialist, ensuring exceptional structural integrity on high-impact dirt tracks.

Frequently Asked Questions (FAQs)

Q: Where is a plunging CV joint typically installed on a race car?

A: Plunging joints are primarily used where the driveshaft must change length as the suspension moves. This makes them standard for the inboard (gearbox) side on FWD cars, and both inboard and outboard locations on RWD or AWD cars featuring independent rear suspension setups.

Q: Does this CV joint include the boot, grease, and mounting hardware?

A: This part number is for the standalone CV joint unit. To ensure complete sealing and performance, it must be paired with the matching GKN Motorsport fast boot kit (Part Number MS6J002) along with specialized high-temperature CV grease and M8 high-tensile mounting bolts.

Q: Can this joint handle the severe suspension angles found in Autograss racing?

A: Yes. GKN Motorsport components are specifically developed to operate at higher continuous angles and handle the abrupt shock loads caused by wheels spinning and gripping on rough dirt track surfaces.
