WHAT SIZE CV BOOT DO I NEED? - STRETCH CV Boots

Choosing the Right Boot for your vehicle or application

What size CV Boot do I need? Let us help you select the best cv boot for your application and provide some handy fitting tips that can be applied to vehicles as well as many other applications.

Step-by-Step CV Boot Selection Guide

Step 1: Measure Your Old Boot size
You need to know the size of the CV Boot you wish to replace. Start by measuring or finding out the following:

- Drive Shaft (Small) Diameter

- CV Joint (Large) Diameter

- Height/Length of Boot
  Note: The height/length of the boot has some tolerance when fitting. See Driveshaft Clamp Position below.

Measuring your old CV Boot — Measure the boot that is being replaced

STRETCH CV Boots are very forgiving when fitting, so don’t feel you need to be millimetre perfect in your measuring. Approximates are often good enough. Note: Split Boots are not as forgiving as the do not stretch.

Step 2: Check STRETCH Boot Sizes

You will find our CV Boots listed on the CV Boot page of our website. Here, you will find information and images of our boots along with their sizes. Clicking on any CV Boot image on this page will open it up and allow you to see the boot size dimensions of the boot you have selected. Use this information to determine which boot best matches your measurements and requirements.

Step 3: Select and Order Your Boots

After following Steps 1 and 2, you should be able to decide if any of our boots are suitable for your application. Once decided, from our CV Boots Page, click the “VISIT SHOP” button for the boot you wish to order, and it will take you through to our shop allowing you to select, confirm and add the boot to your shopping cart.

We offer boots to fit almost any vehicle. STRETCH Boots are also successfully used in many other applications including plant equipment, marine, excavation machinery and industrial applications.

Additional CV Boot fitting tips

Driveshaft Clamp Position is important

The small end of the CV Boot can be positioned further up the shaft if required. Clamping the boot out of the original groove on the shaft and further up the shaft is a simple way to adjust the fit of your boot without needing to cut the boot size down. This fitting option is not possible on non-stretchable boots or if fitting the Split Boot.

Boot correctly fitted with relaxed bellow spacing.

Boot incorrectly fitted with boot bellows too close together and touching each other. The bellows will rub through, and the boot will fail.

Boot incorrectly fitted with the bellows stretched too far apart. If left like this the boot will tear and fail from being overstretched during operation.

Fitting CV Boots on raised or lifted vehicles

CV Boots on Raised Vehicles
CV Boots on raised vehicles can often fail prematurely. We have the solution for the most common cause of these CV Boot failures. STRETCH Boots allow the distance between the bellows of the boot to be adjusted so they are not in constant contact once fitted. This adjustment is achieved by moving the CV Boot small end clamping position so the bellows are spaced correctly. This fitting adjustment is not possible with other Standard, OE or so called Performance 4×4 CV Boots on the market.

If you have a vehicle that is constantly destroying CV Boots… STRETCH boots could be your solution!
See our fitting example images below which apply to both raised and standard height vehicles.

Tripod / Trilobal CV Boots

If you need to replace inner CV Boots, your vehicle might have Tripod/Trilobal CV Boots. Our CV Boots can replace these boots, but you must follow our Tripod Boot Fitting Guide for proper installation. See guide via link: Fitting Tripod/Trilobal Boots

STRETCH Boots are Universal Fitting

All our STRETCH boots are designed for universal fitting. With this in mind we are here to give you the tools and information required to help you make an informed and appropriate boot selection. While we provide this information to you, it is ultimately your responsibility to choose the appropriate boot for your application. We are not able to provide size or fitting recommendations for any specific vehicle or application and we cannot guarantee the fit or suitability of our boots for any given application.

Using the information above, we recommend that the intended fitter checks and determines the most suitable boot using the CV Boot Size information available on the PTW website.

We hope this guide has helped you to understand and select the best CV Boot for your needs. For any further assistance, please get in touch with our support team via Contact Us on our website.
