Irs Cv Boot Kit, 934 Cv Off-Road Style, Sold Each

OVERVIEW

When you''re pushing your long-travel sand rail or heavy-duty Baja Bug to the limit in the dunes or across punishing desert terrain, your drivetrain components are under immense stress. The 934 CV joint is the gold standard for high-performance off-road applications, offering the extreme angles and strength required for professional-grade suspension setups. This EMPI 934 CV Off-Road Style Boot Kit is engineered specifically to protect that investment. Unlike standard street boots that thin out and tear under high-angle articulation, these neoprene boots are designed with extra-thick ribs and a superior material composition that resists the abrasive nature of sand, silt, and mud. By providing a flexible yet impenetrable barrier, this kit ensures that your expensive 934 joints remain lubricated and free from the contaminants that lead to premature wear and catastrophic failure.

This comprehensive kit isn''t just about the boot; it is a complete solution for maintaining your IRS (Independent Rear Suspension) system. It includes a high-quality stamped steel flange that provides a rigid, leak-proof mounting surface against the CV joint body, preventing the grease "weeping" commonly found in inferior setups. The included high-temperature moly grease is formulated to withstand the extreme friction and heat generated during high-speed off-road racing. Whether you are building a new set of axles or performing mid-season maintenance, this EMPI kit provides the reliability you need to keep your air-cooled beast moving. Sold individually, it allows for precise replacement on any corner of your vehicle, ensuring that your off-road adventures aren''t cut short by a simple rubber failure.

PRO TIPS

Proper CV Joint Packing

When installing this kit, don''t just squeeze the grease packet into the boot and hope for the best. For maximum longevity, you must "palm" the grease into the CV joint itself. Place a glob of grease in your palm and press the CV joint into it repeatedly until the grease is forced through the cage and balls and comes out the other side. Only after the joint is fully saturated should you put the remaining grease inside the boot. This ensures that the internal moving parts are lubricated from the very first rotation, preventing "dry starts" that can gall the race and cage.

Venting the Boot for High Travel

High-travel suspension systems cause the CV boot to expand and contract rapidly, which can create a vacuum or internal pressure that leads to the boot collapsing or "ballooning" and rubbing against the frame. A common pro builder trick is to insert a small, flexible plastic tube (like a WD-40 straw) under the small end of the boot before tightening the zip tie. This allows the boot to breathe. Just ensure the vent tube is aimed downward or away from direct dirt entry to keep the internal grease clean and the boot shape stable during extreme suspension cycling.

Clocking the Flange and Boot

Before you tighten your CV bolts through the flange, ensure that the boot is "clocked" correctly so that it isn''t twisted at ride height. If the boot is installed with a twist, it will experience significantly more stress and heat during every revolution, leading to a premature tear. Always double-check your bolt hole alignment on the flange and ensure the boot sits naturally. Also, when using zip ties, ensure they are pulled extremely tight using a pair of pliers or a dedicated tie tool; a loose boot will allow grease to spray out, which attracts dirt and creates a massive mess on your rear suspension components.
