Whether you're a seasoned off-roader or a weekend warrior, understanding the available aftermarket parts can significantly improve your TJ experience. This guide will explore the most popular and impactful aftermarket upgrades for the Jeep TJ.
I. Suspension Upgrades: Elevating Your Ride and Capability
Jeep TJ Aftermarket Parts: Unleash the Full Potential of Your Wrangler
One of the most common and impactful upgrades for a TJ is its suspension. The factory suspension is adequate for on-road driving, but it often falls short when tackling challenging trails.
- Lift Kits: Lift kits increase ground clearance, allowing you to run larger tires and navigate obstacles more easily. Lift kits come in various heights, typically ranging from 2 inches to 6 inches or more.
- Types:
- Budget Boost (Coil Spacers): A simple and affordable way to gain a small amount of lift. Good for fitting slightly larger tires but doesn't improve suspension articulation.
- Coil Spring Lift Kits: Replace the factory coil springs with taller, stiffer springs. Offer improved ride quality and articulation compared to budget boosts.
- Long Arm Kits: The most comprehensive and expensive option. Replace the factory control arms with longer arms, improving suspension geometry and articulation significantly. Ideal for serious off-roaders.
- Benefits: Increased ground clearance, improved approach and departure angles, ability to run larger tires.
- How-to Guide: Installation typically involves removing the wheels, disconnecting the sway bar links and shocks, supporting the axle, removing the old springs and shocks, installing the new lift components, and reassembling everything. It is recommended that you seek a professional installer to perform the installation.
