PRE-ASSEMBLED KIT - FITS LIFT TYPE
Spring Lift or Leveling Kit [1 to 3.5-inch lift]

Spacer Lift, or Leveling kit

These kits cause the upper arms to angle downward toward the ball joints. The Leveling kit or strut lift removes the factory rake angle by lifting the front level with the rear of the vehicle.

  • Coil Spring spacer
  • On-top strut spacers
  • Preload Collar
  • Bilstein 5100 Series, adjustable struts
  • Bilstein 6100 Series, adjustable struts
  • Using lift springs on struts
  • Higher-rate strut springs
  • Adjustable coil over struts

Spring lift kit

These kits cause the upper arms to angle downward toward the ball joints. Spring kits remove the factory rake angle and lift the rear of the vehicle about 1.5" - 2.5"

  • Coil Spring spacer
  • On-top strut spacers
  • Preload Collar
  • Bilstein 5100 Series, adjustable struts
  • Bilstein 6100 Series, adjustable struts
  • Using lift springs on struts
  • Higher-rate strut springs
  • Adjustable coil over struts
Spring Lift with Cradle Drop Kit

Cradle Drop Kit

These kits cause the upper arms to angle downward toward the ball joints. cradle drop lift, cross-member drop, or drop bracket lift kit

  • This style kit relocates the lower control arms on the front of the vehicle by using a drop bracket. These brackets offset the lower control mounting holes by 4", 6", or 8". These kits also include longer steering knuckles to fit within the bigger gap between the upper and the lower ball joints.

Spring lift kit

Spring kits on the front struts

  • Coil Spring spacer
  • On-top strut spacers
  • Preload Collar
  • Bilstein 5100 Series, adjustable struts
  • Bilstein 6100 Series, adjustable struts
  • Using lift springs on struts
  • Higher-rate strut springs
  • Adjustable coil over struts

Example: 4" cradle drop lift with a 2" spring/coil over lift = 6" lift kit. 6" cradle drop lift with a 2" spring/coil over lift = 8" lift kit. When the mounting holes are offset by 4" and the kit is a 6" kit, the other 2 inches are made up from the strut lift or spring lift.

The JBA Upper upper control arms were designed for a Nissan with a spring lift or leveling kit, they work with lifts from 1 to 3.5 inches.

Features That Set JBA Apart:

  • US-Made Steel Tubing: The heart of JBA's upper control arms is the robust 1026 DOM A513-5 domestic tubing, boasting an imperious 1.313" OD x 1.00" ID. It's a significant upgrade that breathes ruggedness into your ride's skeleton.
  • Vibrant Red Powder-Coat Finish: Not only does it catch eyes, but the finish also serves as the first line of defense against the elements—because off-roading involves a collision course with nature.
  • Replaceable Ball Joints: Designed for longevity, the JBA Ball Joints outclass Uni-Balls with an unmatched 90-degree range of motion, letting you tackle any terrain with ease. Grease up the fitting with just a few pumps, and your control arms remain as nimble as ever.
  • Innovative Bushings: The included JBA EZ Lube Bushings redefine durability. With the added convenience of grease ports and pressure relief valves, you needn’t fret about over-lubrication or bushing extrusion. They're built with advanced synthetic elastomer—a polymer known for its incredible tensile strength and elasticity perfect for both daily drives and demanding off-road excursions.
  • Three Grease Ports: Maintenance is a breeze. Simply pump grease until it surfaces between the washers and the bushing—proof of well-lubricated control arms.

With an installation timeframe averaging between 1 to 3 hours, replacing your stock arms with the JBA edition is an investment in immediate improvement. Weighing in at a mere 20 lbs.

Maintenance
Every 3,000-5,000 miles: Grease the ball joint with lithium complex grease fortified with moly, until you see the boots swell (3-4pumps). Grease the arm bushings with the same grease until you see grease pushing out from the EZ Lube ports.
Product FAQs

Does your Vehicle drift off the road after your lift kit is installed?
The JBA upper control arms will fix your problem! No more driving with your hands gripping tightly on the steering wheel to keep your vehicle in the center of the road at high speed. Our upper control arms have 3 degrees of built-in caster.

What is more caster?
"More caster" is the top ball joint moved back toward the cab and the lower ball joint moved forward away from the cab. The angle between the two ball joints is the caster. We have moved the upper ball joint back to give the alignment tech the ability to move the lower ball joint forward. So with the lift kit, you get between 3 & 4.5 degrees of caster, giving your vehicle superior handling on the highway and offroading.

How easy are the JBA arms to maintain?
The JBA upper control arms have 3 grease fittings on each arm. These grease fittings should be greased every 3000 to 5000 miles or when you change your engine oil. If you go in mud pits or across streams with the vehicle, grease the ball joint once you are done for the day.

What is an EZ lube bushing?
JBA has a patent on our control arm bushings. The EZ lube bushings have grease ports with a check valve. When you pump grease in the grease ports it builds up pressure and flows all around the ports in the bushing. When the ports are full the excess grease flows out over the check valves on the flange of the bushings. With the JBA EZ Lube bushing, there is no need to loosen the mounting bolts to release the grease pressure. These bushings will save you about 30 minutes of maintenance! The bushings are Synthetic Elastomer.

What is Synthetic Elastomer?
Synthetic Elastomer is a long-chained polymer with many urethane constituents. Over the years the formulation has evolved to yield stronger, yet softer compounds ideal for on and off-road applications. As the compound advanced to yield higher tensile strength, elasticity, and dynamic load capacity, JBA uses the bushing to help aid and tune suspension geometry and they will not squeak like polyurethane bushings.

What grease should I use in the JBA UCAs?
We recommend MOLY EP LITHIUM GREASE. Mobilgrease XHP™ 222 Special grease is an extended service lithium complex grease intended for a wide variety of applications and severe operating conditions. This grease is designed to outperform conventional products by applying cutting-edge, proprietary, lithium complex manufacturing technology. It is formulated to provide excellent high-temperature performance with superb adhesion, structural stability, and resistance to water contamination. This grease has a high level of chemical stability and offers excellent protection against rust and corrosion. This grease features high dropping points and a maximum recommended operating temperature of 140º C (284°F). Mobilgrease XHP 222 Special grease available in NLGI grades 2 or 3 with an ISO VG 220 base oil viscosity.
Mobilgrease XHP 222 Special grease is designed for a wide range of applications including the industrial, automotive, construction, and marine sectors. Their performance features make them ideal for operating conditions including high temperature, water contamination, shock loading, and extended re-lubrication operations. Mobilgrease XHP 222 Special is an extreme pressure grease fortified with 0.75% molybdenum disulfide that protects from wear under conditions pivoting and other conditions that lead to loss of oil film.

What ball joint do we use in the control arms?
We have CNC machines to make our ball joints out of 4140 steel. The ball joints have 90 degrees range of motion. The ball and socket are protected from the elements with a 100% sealed boot. We Cerakote the outside of the housing to protect it from the elements. There is a grease fitting on the top center of the ball joint where we recommend using a grease gun and adding 3 pumps of grease every time you change your oil and finished playing in mud pits and creeks.

Reasons why we don't use the Uni-ball...
The Uni-Ball is designed for offroad racing applications, these vehicles are disassembled and they replace worn parts on the vehicle after every race. In other words, the Uni-Ball is not designed for the everyday weekend warrior who uses their vehicle for regular transportation more than they go off-road. The open design of the Uni-Ball allows dust, dirt, salt, and other debris to enter the component and wear it out prematurely. The JBA Ball Joint, on the other hand, has a sealed construction that keeps debris and the elements out, extending the life of the joint and allowing you to use it in your daily vehicle. The uni-ball only has 33 degrees range of motion vs the JBA ball joint with 90 degrees.
