Backed by over 30 years of continuous product evolution, this lightweight variant utilizes an optimized profile to offer a significant 20% weight reduction over standard 100mm alternatives. This drop in rotational mass delivers faster throttle response, crisp power delivery, and cooler operational running temperatures under extreme load.\u003c\/p\u003e\n\u003cp\u003eThis plunging CV joint 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.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Technical Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e20% Rotational Weight Saved:\u003c\/b\u003e Highly lightened outer geometry sheds crucial unsprung rotational weight without structural compromise, keeping hub assemblies nimble over rough terrain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOptimal Plunging Design:\u003c\/b\u003e Features +\/-8mm of linear axial plunge travel to effortlessly accommodate dynamic track wheel travel and suspension geometry changes without binding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCooler Operating Temperatures:\u003c\/b\u003e Precision-machined internal race profiles reduce friction, mitigating extreme heat buildup under heavy load to prevent premature grease breakdown.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUnsurpassed Reliability:\u003c\/b\u003e Manufactured by GKN, the world's leading driveline specialist, ensuring exceptional structural integrity on high-impact dirt tracks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cb\u003eFrequently Asked Questions (FAQs)\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eQ: Where is a plunging CV joint typically installed on a race car?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e Plunging joints are primarily used where the driveshaft must change length as the suspension moves.
