Buying Guide
- What size do I need? Look at shaft diameter and end-port measurements. If your CV joint has a non-standard size, consider kits with multiple port options or split designs that can be trimmed.
- Full boot vs split boot: Split boots (like CVS18) can fit a variety of sizes and simplify installation, but some users prefer full-coverage boots for a tighter seal in extreme conditions.
- Clamps and accessories: A kit with stainless clamps and cable ties reduces additional purchases. Check whether a reusable boot tool is included for easier installation.
- Material and durability: Rubber boots with tear resistance last longer in harsh environments. Confirm resistance to oil, grease, and temperature variations for your vehicle type.
- Installation considerations: Some boots allow installation without axle removal. If space is limited, choose smaller, flexible boots with a compatible installation method.
- Vehicle coverage: If you own multiple vehicles, prioritize kits with larger end-port options or universal compatibility to minimize future purchases.

- How do I know if a boot is the right size? Compare the boot length and end-port diameters to your existing boot and CV joint specifications.
