Barnes 4wd - Enduro Joint
We recently switched from using a spanner nut system to a new more durable snap ring system!

When Barnes 4WD designed the Enduro Joint we combined the best materials, the best manufacturing processes and the best steel and polyurethane treatments available all in one joint.
The body of the Enduro Joint is Forged 4140 heat treated Chromoly steel. We did not try to cut any corners by making a short threaded shank like a heim joint instead we give you 3.25” of 1.25-12 threaded shank.
That is over one inch longer than 1.25” heims on the market. The Enduro Joint’s ball is made from 52100 bearing steel and incorporates the high misalignment spacers all into one piece of steel that provide 40 degrees of misalignment. Forty degrees of misalignment will net almost 33” of travel on a four foot control arm.
The spherical bearing is then Hard Chrome plated to provide an ultra smooth surface and has proven to provide excellent corrosion protection. The mounting width of the Enduro Joint is 2 5/8” and has a 5/8th or 9/16ths inch bolt hole.
The cups that the spherical bearing rides on are an 88 durometer polyurethane that ensures maximum life, no squeaks like heim joints and they help to dampen axle vibrations felt through the chassis.
The body of the joint is gold zinc plated to ensure that the Enduro Joint looks great for the life of the joint. Once the joint is fully assembled we are still not finished making the ultimate joint. Every completed Enduro Joint assembly is then Cryogenically Treated to give the Enduro Joint the most strength and greatest wear characteristics possible.
They can be found in both LEFT and RIGHT threads with both 5/8th and 9/16th inch bolt holes here:
Barnes 4wd Enduro Joint
The Enduro Joint’s ball is made from 52100 bearing steel and incorporates the high misalignment spacers all into one piece of steel that provide 40 degrees of total misalignment. Forty degrees of misalignment will net almost 33” of travel on a four foot control arm. The spherical bearing is then Hard Chrome plated to provide an ultra smooth surface and has proven to provide excellent corrosion protection.
The mounting width of the Enduro Joint is 2 5/8” and accepts a 5/8” bolt. The spanner nut locking mechanism ensures that the joint will not come apart and if ever needed an easy way to add more bearing preload. The cups that the spherical bearing rides on are an 88 durometer poly urethane that ensures maximum life, no squeaks like heim joints and they help to dampen axle vibrations felt through the chassis. The body of the joint and the spanner nut are gold zinc plated to ensure that the Enduro Joint looks great for the life of the joint.
Once the joint is fully assembled we are still not finished making the ultimate joint. Every completed Enduro Joint assembly is then Cryogenically Treated to give the Enduro Joint the most strength and greatest wear characteristics possible.
all the time
