Nth Degree

UPDATED 8/20/2020: We are currently taking names for people who are interested in ordering new gyrojoint kits. When we get to 30 orders, we will get more made. We currently have 28 pre-orders. So we will be placing our order SOON.  Please EMAIL us at info@boulderbars.com and tell us how many gyrojoint kits you want. You can order as many as you want. 


They will be $219.00 or slightly higher for the FULL set of all 8 standard Gyrojoints (2 white and 2 black cupped and 4 slotted ends). 


You can also order the "HEMI" Heavy Duty Gyrojoint kit, which is just what we are calling the Gyrojoint kits using ONLY the harder durometer black cupped gyrojoints on both the front and rear (the white bushings that are used in the front of the standard kit are softer and not used in the Hemi kit).  The Hemi kit is meant for jeeps that have a V8, or they tend to tear the white bushings, or for those that are looking to extend the life of the front bushings. They MAY cause a slight amount of engine vibration transfer. Most people don't notice this, but if you are super tuned-in to your Jeep and every little thing about it, you MIGHT notice it.  So keep that in mind.  The HEMI Gyrojoint kit will be approx. $229.99 or slightly higher. We won't know for sure until our order is made what the final pricing will be.


In the GyroJoint kit that we are having built soon:

  • Nth Degree Gyrojoint Isolator Replacement Kit (set of all 8 half-gyrojoints).

  • Placement of GyroJoint Isolators:

  • Black "cupped" pieces (look just like the white parts, but black) are for the rear lower control arms at the frame end. (x2 pieces)

  • White "cupped" pieces are for the front lower control arms at the frame end. (x2 pieces)

  • The other four black pieces with the "slot" in them can go in the front or in the rear opposite of the black/white pieces. (x4 pieces)

  • NOTE: The HEMI Gyrojoint kit will have the same parts as described above, except instead of the white cupped parts it will have front BLACK Cupped parts.



(timing for parts is TBD at this point, but we're hoping for the end of the year): 

  1. Front Upper Control Arm Bushings (there are FOUR total of these bushings, two soft and two hard). We are currently taking pre-orders for the Front Upper Control Arm Bushings. $57.99 for the complete kit. Call to get your order placed 909-866-4800.

  2. Rear Stinger/Slider Bushings (they look like a small hockey puck shape and are found at the point where the stinger mates to the slider - just the the rear of the "Nth" degree laser cut logo in the stinger). - Your Jeep takes TWO of these bushings. - Working on getting these....we'll update this page when we have more info.




If you are desperate for parts, below is what we have left (some parts are used).

Below are Nth items that we have left in stock. The bottom of this page contains the items we no longer have in stock and that are no longer available.

  • We have 3 used good condition take-off slotted gyrojoint bushings a la carte $15 each.

  • We have 2 used good condition black cupped gyrojoint bushing - $15.

  • We also JUST FOUND 4 used GyroJoint STUBS (looks like a hitch ball). They are 49.99 each.


Please call Heather at 909-866-4800 or email info@boulderbars.com to order.

FOR OTHER PARTS: As of 6/10/20, all parts we had left in stock in our warehouse were sold, except for what is listed below. Sold parts are in the following section. If you don't see it listed, sorry we DON'T have it.


  1. Nth23001AA: Nth Degree Laser Cut Gyrojoint Wrench w/laser cut Nth Degree logo (small end for stubs, large end for jam nuts). -1 left in stock. $20 each

  2. IN STOCK Stinger Bushings (they look like a mushroom) (from front of rear stinger to tummy tucker at the horseshoe - QUANTITY NEEDED TO REPLACE WHAT YOU HAVE IS 2 bushings per Jeep). See the picture below for what the rubber 1" and 1.25" Diameter Stinger-to-Tummy Tucker bushings look like. Please measure the "non-head" side of your bushing before ordering. The 1.25" OD Diameter (with a 3/4" hole, uses a sleeve with a 1/2" bolt). In stock. $8.99 for either 1" or 1.25" bushing, each. The sleeve is $9.99.

    NOTE: A very few of the newer lift kits used the Urethane 1.25" OD Diameter Stinger bushing at the horseshoe (tummy tucker to stinger) with a metal sleeve that the bolt goes through. Those larger 1.25" OD Diameter bushings use a 3" long sleeve with a 1/2" bolt hole. Please measure your bushing at the "non-head" side before ordering. Also, some kits used a shorter sleeve, so your sleeve may be shorter than 3" long - if it is, then ask for the new sleeve as the shorter sleeves should not be re-used as they can allow the bushings to be squished when tightening up the bolt. The cost for the 1.25" Urethane bushing and sleeve kit is $29.99. (comes with two 1.25" stinger bushings and one 1/2" hole, 3" long sleeve)

  3. IN STOCK Tummy Tucker Isolators (see photo below): $29.99 each. In stock. Your Jeep has TWO at the Tummy Tucker/Transmission.

    2. IN STOCK 5/8" shank x 5/8" ID on heim - used on the oldest lifts) -- $36.99 each

      Specify which size you need - Nth Degree used all three sizes and sometimes mixed/matched regardless of how old your lift is, so you must MEASURE the Stinger Rod you have installed on your Jeep now before placing your order. We will send you the size you say you have and if it's wrong, you can pay to ship back the heim joint and pay for shipping back with the correct size part - so please MEASURE your heim first to avoid wasting your money on shipping twice!
