Suspension systems have been one of the most upgraded parts of a Jeep. Suspension systems are also one of the most important upgrades you can do to a Jeep. The lane is wide with systems from a variety of companies, and the old saying you get what you pay for could not apply more than it does in the area. The mastery is in the design first and then manufacturing quality, and the good guys out there doing it know how to do it right.
Let’s zero in on the most important part of a suspension kit, the end joint. End joints are something most don’t give much of a thought about, they are just part of the kit and we assume their job is easy. I assure you, that’s not the case. They are different end joints from different manufacturers, and they definitely are not all equal. Rather than talking about lessor types made by other brands, let’s cut to the chase and talk about the best.
Johnny Joints are manufactured by the industry’s best, RockJock 4×4. RockJock 4×4 is a John Currie owned company, based here in Southern California. John has been innovating Jeep parts since the 80s, and now joined by his kids Brandon, CEO, and Amanda, VP of Finance, together keep the company in the forefront of the industry.
What is a Johnny Joint, and why do you need one? Simply put, it is the original urethane bushed spherical ball joint. Designed to be the best, the Johnny Joint is the go to for not only customers, but the brands that build their suspension kits to be the best. Johnny Joints are proven to last longer and out perform their competition with articulation and durability, and that is exactly what you want when you purchase suspension. Here’s a closer look at Johnny Joints straight from the guys who know it best.
Unmatched Durability Under The Harshest Conditions – The Johnny Joints installed under our two company Jeep JKs, have conquered the Rubicon trail too many times to count, lead countless trail runs at Moab, have pre-run the full length of the Baja 1000 multiple times, and have covered more than 70,000 miles of highway driving with zero failures or parts replacement – no other high articulation suspension joint on the market comes close to matching the durability of the Johnny Joint!
Industry Leading Articulation – Johnny Joints are designed to allow your vehicle’s suspension to move freely without restriction. The smooth hardened steel ball center rotates inside the proprietary urethane bushing without binding or tearing the bushing material like rubber or sleeved urethane bushings. Johnny Joints are available with up to 42 degrees of articulation per joint, 30+ degrees is typical (varies based on mount width and bolt diameter).
Quiet Smooth Operation – Unlike steel heim joints, Delrin or hard urethane bushings, Johnny Joints do not squeak, clunk or make otherwise annoying noises. The smooth steel ball center rotates quietly inside the proprietary urethane shell that provides a firm positive cushion to quiet and dampen trail impacts and road noise.
Simple Maintenance – Johnny Joints, like any serviceable parts on your vehicle, will last longer if you give them just a little maintenance. To keep your Johnny Joints happy, just give them a small shot of grease through the zerk fitting every 6 months or before any major off-road outing.
Fully Rebuildable – Wearing out a Johnny Joint is an uncommon occurrence, but if it should happen, every Johnny Joint can be fully rebuilt with one of our very affordable rebuild kits that contain: new urethane, side washers, and a retaining snap ring.
So, if you’re building a Jeep that can tackle anything you throw at it, or a nice overland style rig that you need to rely on in any situation, RockJock 4×4 has entire catalog of awesome products for you. Upgrade that existing suspension or maybe install a suspension kit for the first time, either way do it with RockJock4x4.com and separate yourself from the pack.
