High Angle CV Boot Kit (ORS-HB201)

High Angle CV Boot Kit

Thank you for purchasing our High Angle CV Boot Kit!

Notice to customer: This High Angle CV Boot Kit is designed to reduce CV boot wear in high angle situations. This part is not designed to fit in the same manner as the OEM CV boot. Special fitting is required for this product to function properly. It is the sole responsibility of the installer to ensure the CV boot fits and functions properly. By installing this product the customer accepts these terms.

Do not wash these CV boots in high-powered solvents, this has been known to damage the boots.

Read and understand these instructions before beginning installation. A tensioning tool for “band-it” type CV boot clamps, and/or a standard crimp-type CV clamp tool are required for installation. There may be a large rubber band around the CV boot, this is intended to relieve stress due to angle; we recommend leaving it in place. Stretching these boots is required in many applications. Due to their material, these boots will stretch a good amount safely.

  1. Drain the front differential and remove the axle assembly per manufacturer’s instructions.
  2. Remove both clamps from the inner CV joint. Slide the CV boot toward the outside of the axle shaft.
  3. Remove the axle shaft from the inner CV joint per manufacturer’s instructions. Remove any spring clips or snap rings. Remove the inner CV boot from the axle shaft. Do not discard.
  4. Replace/service the outer CV joint/boot, if applicable, at this time.
  5. Carefully clean the inner CV joint and related parts.
  6. Slide the new high angle CV boot over the axle shaft.
  7. If the inner CV joint case is not round but “tulip” shape, perform this step. Cut the inner flange from the original CV boot. This is the section that originally sealed over the CV joint housing. Slide this section of the boot over the CV joint case to its original position. The high angle CV boot will install directly on top of this section of the original boot. Only one clamp will be used in this place, over the high angle boot.
  8. On ’00-’06 Tundra OEM inner CV joints: Locate the thin sheet metal extension on the outside of the joint (original boot fastened to this piece). Cut approximately ½ of the extension off. Ensure that the CV joint will travel feely without contacting this extension. Do not cut this entire piece off. Be sure to shield the joint and keep the joint free of all debris during this step.
  9. Assemble the inner CV joint per manufacturer’s instructions. Be sure that all snap rings and spring clips are in their proper location. 2 or 3 grease packs will be provided, and may vary in size. Estimate the total weight of all grease packs and evenly divide the grease per side. Place the majority of the grease in each inner joint, and place the remainder inside each CV boot. It is very important to keep the larger sealing surface of the boot and CV joint case clean and dry.
  10. With the CV joint extended to its middle position, slide the high angle CV boot over the inner joint case and place directly on top of the CV joint (or the remaining section of original CV boot). Be sure the boot’s inner (larger) flange is placed in the joint (or boot) groove that will retain the boot in position.
  11. Slide the outer flange (small) of the high angle boot over the axle shaft until the boot rests in a neutral position (no tension on boot in either direction). This may place the outer flange in the original machined landing on the axle shaft, or this may require that the outer flange is set past the original machined landing (which is OK).
  12. Using a tensioning tool, install and tighten the provided CV boot clamps on each end of the high angle CV boot. Ensure that the CV boot will hold firmly in position.
  13. Install the axle per manufacturer’s instructions and fill the differential with the proper lubricant.

  • Beldon says:

    Will this CV boot fit my 05 Toyota tundra?

    • Mike Caskey says:

      Yes, it will fit ’00-’06 Tundras. As mentioned in the product description, this boot will require modification to the original inner CV boot mounting flange on Tundra models.

  • Robert Ries says:

    Installed mine today. 1996 Tacoma with ADD (ah, the irony of that acronym…)

    So, it has the tulip-style inner joint cases. Cut the flange off the original boot (straight sheet-metal snips work very well for this). Set it back on the inner case and tried to stretch the new boot over it… Damn near impossible.

    Found an alternate procedure that seems to work well. Before installing new boot on axle, partially fold flange and install in the boot first. It should stick out about 1/8″ when seated correctly, but flush works as well. Install on axle, then install inner joint bearing assembly on axle. Pull boot back, fill with grease packet. Install axle per instructions/manual. Now fit the boot/flange onto the inner joint case.

    The next problem is that the included inner clamps are too short for this assembly. I’ve used zip-ties for a temp fix, but will be looking for some actual clamps tomorrow after work. I’d suggest sourcing some longer clamps and provide both, or offer it as an option, to cover all the possibilities.

    Last nit-pick, the instructions say to use 2 packs of grease per side, but my set only came with 3 packs total, not 4. Since my CV joints were almost brand new, I salvaged most of the grease in the original boots, and had plenty, but this needs to be closely monitored in the future.

    Over all, seems to be a pretty good product. I bought it because my CV axles, purchased 3K miles ago to go with a Toytec 3″ lift, tore the passenger-side boot last week, and the driver’s side was showing heavy wear, both from the bellows rubbing. Hopefully this fixes the issue, I’ll keep you posted.

    Sorry, I didn’t get pictures of anything in work, too busy, and too much grease splattered around to work a camera myself.

    • Mike Caskey says:

      Thank you for the thoughtful input. We recommend 1.5 packs of grease per side and have recently changed the instructions to reflect that. We will also strive to be sure adequate clamps are provided. It can be difficult to install the boots over the sealing portion of the original boot and we appreciate your ‘take’ on it!

  • Josh says:

    Do these boots work on the outters as well?

  • MATT says:


  • Vincent says:

    Will these work (inner and outer) for an 09 toyota tacoma sport?

    • ORS says:

      Although the application has not fully been tested, they have worked on these inner joints thus far. Boot dimensions: 3.5″ ID and 1″ ID, about 6″ length. They can stretch quite a bit.

  • zach says:

    Would you happen to know if these will fit a 2002 dodge ram 1500?

  • John Dauma says:

    Will the High Angle CV Boots fit an FJ Cruiser axle and CV?

    • ORS says:

      Yes, these boots have been proven to fit FJ Cruiser/’05 and later Tacoma/’03-’09 4Runner. As with earlier applications, it will require the use of the original boot’s sealing flange. Our HA boots have to be stretched to fit but the silicone material takes well to stretching.

  • Brooke says:

    I just bought outer boots, but I’ve discovered that my inner boots are busted as well. Can I buy these to replace the inner boots I have on my 01 4Runner? It has both a body and suspension lift.

  • carlos says:

    Would these boots fit in Isuzu vehicross or trooper.

    • ORS says:

      We have not tried this application. These High Angle Boots have an ID of 3.5″ on the large end and 1″ on the small end. Their ‘free-standing’ height is about 6″. The do stretch pretty well when used over a larger diameter. They are round. If your CV joint housing is not round, they will be installed over the sealing portion of your original boot.

  • Jordan oconnor says:

    Installing a lift on my 98 Toyota t100 and wondering if these boots will work? Has anyone done this before? Any help really appreciated! Thanks

    • Mike Caskey says:

      We have not yet tried this application. These High Angle Boots have an ID of 3.5″ on the large end and 1″ on the small end. Their ‘free-standing’ height is about 6″. The do stretch pretty well when used over a larger diameter.

  • Jason says:

    These actually fit on my FJ Cruiser outer CVs, is there any reason to not do this?

    • Mike Caskey says:

      These will also work on FJ Cruiser applications. As stated in our instructions, this will require the use of a small portion of the original FJ Cruiser CV boot to create a round seal surface for the new boot.

  • Michael says:

    Do you have any pictures of the ORS – HB201 boots installed on a 2000 to 2006 Tundra?
    I’m not exactly sure where the large end of the boot should “land” on the cv joint. It looks like it could be stretched onto the larger part of the joint. I have the “Tulip” shaped flange that is shown in the picture above.

  • Kyle Taaffe says:

    I have 2005 Ram 1500 4×4 and my passenger side cv axle boots inner and outter keep tearing. I have a 3in. Rancho lift and a 3inch Supreme Suspensions leveling kit. I havr heard of the high angle cv boot kit but will it fit my truck amd how much does it cost?

    • Mike Caskey says:

      We have not tried these boots on anything outside Toyota. The boot ID is 3.5″ and 1″, the boot stands about 6″ tall. They do stretch very well. We suggest measuring your CV joints to compare.

  • Craig says:

    Will these work on a 2002 4Runner without reusing part of the old boot?

    • Mike Caskey says:

      These will require the use of the original boot’s sealing lip on original (tri-lobal shaped) 2002 4Runner Inner CV joints. The only exception is applications with round-shaped inner CV joint housings.

  • Troy says:

    On the tundra application,what would happen if the entire extension(the gold part pictured) was taken off?

    • Mike Caskey says:

      The extension is also used to prevent the joint from over-extending and falling apart. It is important that roughly 1/2 of the extension remains to keep the joint together. I would guess that the danger of the joint over-extending under use w/ a ‘stock’ suspension setup is not likely but would not want to find out the hard way, particularly with a lift and/or long-travel.

  • Kyle says:

    This kit came as order but there is a orange rubber ring installed around one of the larger boot flanges. Does this required to be removed before install(installed for shipping only) or this ring kept on for install?
    My assumption is this is kept on to help to keep the boot shape during regular driving

    • Mike Caskey says:

      Your assumption is correct. The answer is ‘hidden’ in the customer notes near the top of these instructions. This band should stay in place, it helps the boot retain it’s shape under heavy compression/extension.
