Air Ride

When installingfront only air ride kits;

Review the individual components neededif the bike alreadyhas a mix of other air suspension parts as follows;

Front air cartridge
Front Valve(s)
Switch harness

If “instant up” is desired then you would need an FXA-2012-1 on 49mm bikes (with our rear shocks). We generally recommend (FXA-2012-2) dual tanks on 41mm front bikes or 49mm bikes with our front shocks and Monroe rear shocks.  The Monroe shocks require 2X pressure and volume.

Also, confirm there is an adequate compressor to work with our pressure switch setting.  A Viair 95C or larger works fine. Legends, tricky air,  or the smaller gas compressor will not work, those compressors do not generate enough peak pressure. Dirty air, Platinum, Arnott (with the larger comp), Skully, Xotic kits all have compatible compressors.

Brake Hose Kits

Part # BHK-031 Single Disc Conversion Kit, ABS, 14 up models. Install Directions. First, replace the upper hose. Use the short hose, 60”, that came with the kit, also use one of the 90-degree banjo fittings and the large hard fitting at the top on the master cylinder end.
Next, remove the line on the right side of your ABS unit and block that off with the spacer and 2 washers provided, and your stock banjo bolt. Lastly, use the 72”  hose and fittings to change your left lower hose.


Are our brake pads included when I purchase HHI Calipers? YES.

Does HHI offer caliper rebuild kits? YES. 
Click here.

Will HHI rebuild my HHI caliper? YES. Some of our older-style calipers can no longer be rebuilt. Typically we will need the date code to determine our ability to rebuild. Calipers made before 2003 usually can not be rebuilt. Click Here to view the date code placement on caliper.

Where can I purchase HHI replacement brake pads? 
Click here. Brake pads can also be ordered from HHI Distributors and dealers worldwide.

When doing a single disc conversion on a 2008-later Touring and using a 6 piston caliper with a 13” rotor is it necessary to change the master cylinder? It’s not necessary to change the m/c however it will have less brake lever travel and a stiffer lever feel.  The smaller bore size of 9/16” like that used on a Softail will improve brake performance and lever response but not significantly.

When doing a single disc conversion on a 2007-earlier Touring model and using a 6 piston caliper with a 13” rotor is it necessary to change the master cylinder ? Yes it is a requirement to change the stock 11/16” bore m/c to a 9/16” bore size as used on a single disc brake model bike.  This change provides the correct operational volume and pressure in a single brake caliper application. The smaller bore size of 9/16” is typically used on models such as a Softail or Dyna

What is the bolt pattern for HHI calipers?  All 99 earlier direct bolt-on calipers are 3.5". 2000 up models are 2 7/8"

Fork Legs

What is the proper amount of fork oil?  Always refer to your Harley manual to determine correct fork oil levels. Typically 41mm HHI fork legs: Use 10 ounces wet, 11 ounces dry. 49mm HHI fork legs; use 22 ounces wet and 24 ounces dry. Adjust per your manual's directions. NOTE: Use 2 ounces less if fork legs contain travel stop limiters (bump stops).

What weight fork oil is recommended? 20 weight.  Harley Davidson Screamin Eagle Performance Fork oil is 20 weight. Type E and type B Harley Davidson fork oil are lighter weight and not recommended.

Does HHI use special seals in fork legs? HHI seals are the same size as stock Harley seals.


How do I remove the pinch bolts from HHI Triple Trees so I can remove the fork tubes? If your HHI Triple trees use pinch bolts click here. for installation or removal instructions..


How does the 18” rotor mount?

 The outer clamp ring is used to secure the rotor to the hub.  When ordering a wheel and an 18” rotor the clamp ring is included at no additional charge as it is supplied with the wheel assembly.

 You can order the clamp ring separately as would be needed if ordering just the 18” rotor to fit an existing wheel.  However if this is the intent, please remember the hub has a special offset to accommodate the big rotor.  If you are desiring to convert a Renegade wheel to an 18” rotor we would sell you a complete hub assembly which would include the clamp ring.  Otherwise, send us your hub and we will modify it for a nominal charge.

Can I order the clamp ring separately? Yes

Will HHI modify my hub for an 18" brake ? Yes, HHI will modify your existing hub to take the New HHI 18" brake conversion for a nominal charge. Please call the sales department for further information. 1-877-442-5837


 How do I install HHI Bars on my 2015 up Road Glide? HHI 2015-up Road Glide bars do not use the factory locating pins which restrict the adjustment of the bars and controls. Installation of these bars will require the removal of the locating pin found in the lower riser.  This can be accomplished without removal of the stock riser by simply pushing down on the pin until it is flush.  The new style Road Glide master cylinder clamps also have a locating feature that will need to be removed and clearanced for proper fitment with our bars.  Alternatively, one can use the traditional style clamps as found on all other HD models.
