a

Heim Joints / Rod Ends - Choosing the Right One - Rock Krawler Tech Series

hi I'm Jeremy with rock color we want to

go over a little bit of subject matter

with you today that a lot of people talk

about and nobody seems to really know

the details regarding what they're

actually talking about heim joints

there's several different style

constructions materials use things of

that nature that affect what the

application for where you should

actually use your Heim job you have your

lower costs lower grade commercial style

your mid cost mid grade which is

typically an X M series from the most

companies and your high quality chromoly

three-piece with teflon joints the first

series of heim joint is again your

typical commercial series you can get

the housings in a standard low carbon or

some people off on an aluminum or

stainless steel you can get them with

grease fittings Teflon liners things of

that nature and they also pretty much

carry all the same ball construction 50

to 100 series steel that is chrome

plated this application is really not a

high strength application it's a very

very sloppy fit application something

you would not want to use in a

suspension component or any kind of

steering linkage or anything of that

nature typical usage in most off-road

vehicles is your steering column support

the second style heim joint construction

is typically called your XM series it's

more of a little bit more expensive than

your commercial grade it also has a

little bit different style Raceway they

are typically self lubricating joints a

little bit tighter you can get the

housings in chromoly slow carbon steel

stainless steel aluminum but they also

include what is called typically called

a nylon fiber Raceway you do see some

people using these in suspension

components and track bars they typically

are not ideal for those applications the

injection molded Raceway that you see is

again typically a nylon fiber type

construction Nayla fiber is a thermal

plastic not a thermoset

and for those of you they do not know

the difference is your thermo sets are

typically your urethanes your rubber

products things that are very good with

absorbing energy and coming back from

that energy deflection thermo plastics

are typically things of again nylon hard

injection molded plastics that when they

take impact energy they typically

plastically deform and they do not come

back to shape these can loosen up very

quickly in your applications especially

where steering geometry is critical and

again we do not advise using them they

do have some good uses for some support

linkage and things of that nature and

again they are more cost effective than

your very high-end ones that we're going

to touch on next but they do cost a

little bit more than your standard

commercial grade so when you're looking

at your hind joints check out the

plastic raceways and be aware of what

you're dealing with your best quality

construction time joints for suspension

steering things of that nature are

typically your three-piece units you can

get them with grease fittings or most of

them will come with a Teflon liner for

self lubrication the housings themselves

are typically a heat-treated chromoly

with a hard steel race again with a

Teflon liner for lubrication and a 50 to

100 series chrome-plated ball these are

very strong units they take impact

energy better than all the other units

that are out there and they also with

some manufacturers you can actually

specify the surface friction on the ball

providing a nice tight fit things this

nature are available from FK and rot and

supply and you can definitely notice a

difference in their longevity and

materials I hope you found this info

session on the different structure a

heim joints useful hopefully I helped

you choose better joints for your builds

and you have a better understanding of

why we choose a three-piece heim joint

with Teflon as far as our suspension

components and all related parts are

concerned because we feel it's the best

in the industry
