Trailing Arm Kit, 3X3 Arms, 930 CV Joints, for Type 1 Trans

OVERVIEW

Transform your off-road machine into a high-performance desert conqueror with the Appletree Automotive 3x3 Trailing Arm Kit. Designed specifically for enthusiasts who demand extreme suspension travel and a wider, more stable footprint, this kit is the ultimate solution for Baja Bugs, sand rails, and heavy-duty dune buggies. By extending your rear wheel placement 3 inches outward and 3 inches backward, you significantly increase the wheelbase and track width. This geometry change not only allows for much larger tire fitment without body interference but also provides a dramatic improvement in high-speed stability and crawling capability. Whether you are skipping over whoops or navigating technical rocky terrain, these D.O.M. steel trailing arms provide the structural integrity required to handle the stresses of aggressive off-roading without flexing or failing.

The heart of this kit lies in its massive 930 CV joint conversion, which is a significant upgrade over standard Type 1 or Type 2 components. By utilizing the 930 (Porsche-style) CV joints, this system allows for extreme axle anglesup to 25 to 28 degreeswithout the binding or overheating issues common in stock setups. This kit is specifically engineered to adapt these heavy-duty 930 components to a standard Type 1 Beetle transmission, giving you the best of both worlds: the reliability of a VW transaxle and the brute strength of a professional-grade drivetrain. Every component, from the 28-spline chromoly axles to the precision-machined drive flanges and stub axles, has been selected to ensure a seamless installation and long-lasting durability in the harshest environments. Don''t settle for mediocre suspension when you can bolt on a professional-tier long-travel system that is built to take a beating.

FITMENT

This kit is designed for vehicles utilizing an Independent Rear Suspension (IRS) configuration and a Type 1 (Beetle-style) transmission. Suitable for the following applications:

PRO TIPS

1. Proper CV Lubrication and "Burping"

When assembling your 930 CV joints, it is critical to use a high-quality, high-molybdenum (moly) grease specifically designed for high-angle CV joints. Don''t just fill the boot; ensure the grease is packed thoroughly into the cage and around the balls of the joint. After installation, "burp" the boots by inserting a small, blunt screwdriver between the boot and the axle to release trapped air. This prevents the boot from expanding like a balloon due to heat and pressure, which can lead to premature boot failure or tearing during extreme suspension cycles.

2. Install Limit Straps to Protect Your Drivetrain

While 930 CV joints are famous for their high-angle capabilities, they are not invincible. It is vital to install high-quality limit straps to prevent the suspension from "drooping" past the maximum operating angle of the CV joints. If the suspension hangs too low, the CV joints can bind, causing immediate and catastrophic failure of the cage or the transaxle flanges. Set your limit straps so that they stop the arm''s downward travel about 1 to 2 degrees before the CV joint reaches its maximum bind point.

3. Re-Torque After the First Run

Off-road vibrations and the extreme torque loads placed on 3x3 arms and 930 hardware can cause components to settle. It is a mandatory safety practice to re-torque all 24 CV bolts and the trailing arm pivot bolts after your first couple of hours on the trail. We highly recommend using a small amount of blue thread-locking compound on the CV bolts and marking them with a paint pen. This allows you to perform a quick visual inspection during pit stops to ensure no bolts have started to back out under the stress of the desert terrain.
