Product Details

RockNuts from RockJock are the evolution of locking nuts that render traditional jam nuts obsolete! RockNuts solve the age-old problem faced by Rock Crawlers and Racers alike – your get your suspension set up to twist and move, suspension joints bind up in brackets and jam nuts pop loose. This potential issue is not only one more thing on your maintenance checklist before an event or a race, but loose jam nuts will cause a suspension joint and the arm it is threaded into to destroy one another if they are not tight. The collet design of the RockNut provides a steel nut with a female taper and a steel bung or aluminum control arm with an intersecting male taper. When tight, the components are bound together and are bound onto the threads of the suspension joint with incredible force. This RockNut kit for suspension fabricators provides you with a 1 1/4 in.-12 RH thread steel nut and steel weld-in bung that is designed to be inserted into a 1 3/4 in. x .188 in. wall tube. Finish is black zinc plating on the nut and raw, weldable steel on the bung.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

I purchased a upper and lower set of control arms from core 4x4 they came early then expected and seem to be very nice quality I ran into a complication installing them and emailed them my question I was expecting to get the response maybe the next day because it was after hours I got a response in about a few minutes which allowed me to finish the project that day I super appreciate that, the products are good strong lifetime warranty and their customer service is top notch

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.
