Fits 1987-1995 Jeep Wrangler (Base, Islander, Laredo, Renegade, Rio Grande, S, Sahara, SE, and Sport).

The SuperPro KIT108K leaf spring bushing kit is designed to address common suspension instability in 4WD vehicles. Often overlooked during suspension upgrades, leaf spring bushings are critical for stabilizing rear axle movement. Worn or soft OE rubber bushings allow the rear axle to shift, causing unpredictable passive steer and making the vehicle wander across the road. This instability is significantly magnified when carrying heavy loads or towing trailers, RVs, and boats.

By replacing factory rubber with high-performance SuperPro bushings, you regain control over your Jeep's rear-end geometry. These bushings provide a more consistent spring rate and axle alignment, ensuring the vehicle remains stable under heavy braking and during cornering.

• Improved Handling: Eliminates rear-end passive steer and highway wander.
• Braking Stability: Reduces axle movement for more predictable stops.
• Heavy-Duty Performance: Engineered to handle increased loads and oversized tires better than standard rubber.
• Part Number: KIT108K
• Kit Includes: Complete leaf spring bushing set for front and rear applications.

Fits select 1998-2007 Lexus LX470 and Toyota Land Cruiser Base models.

The SuperPro KIT097K Rear Trailing Arm and Panhard Rod Bushing Set is designed to replace worn, soft factory rubber components with high-performance polyurethane.

SuperPro DuroBall control arm bushings are engineered to solve the inherent trade-off between performance and comfort. By encasing an isolated spherical bearing within a proprietary polyurethane shell, these bushings deliver the precise articulation and steering response of a bearing-style design while maintaining the noise, vibration, and harshness (NVH) mitigation expected of a street-driven vehicle.

Worn factory rubber bushings allow for significant deflection and dynamic alignment changes under load, leading to vague steering, increased tire wear, and poor handling. The DuroBall assembly (DURO4425K) replaces these soft OE components with a durable, Australian-made solution that is resistant to extreme temperatures, oils, and road contaminants. This kit is especially effective for vehicles with larger wheel and tire packages or upgraded braking systems that put additional stress on the front suspension pivot points.

• Proprietary engineering-grade polyurethane formula for superior durability
• Isolated spherical bearing provides precision steering and maximum articulation
• Maintains OEM levels of noise and harshness isolation
• Unaffected by extreme temperatures, oils, water, or coolant
• Standard alignment configuration (Std. Alignment)
• Designed, engineered, and manufactured in Australia
• Manufacturer Part Number: DURO4425K
• Limited Lifetime Warranty

Fits 2008-2015 Mitsubishi Lancer Evolution (GSR, MR, MR Touring, SE, and Final Edition).

SuperPro DuroBall bushing kits bridge the gap between track-focused spherical bearings and street-compliant polyurethane. By encasing an isolated spherical bearing within a proprietary polyurethane shell, the DURO3737K kit provides the precise articulation of a bearing with the noise, vibration, and harshness (NVH) mitigation of a bushing. This replaces the soft factory rubber that allows excessive deflection, leading to sloppy handling and irregular tire wear.

Designed to maintain correct suspension geometry under high loads, these rear upper inner control arm bushings are essential for Evo X owners running upgraded brake packages or high-grip tires. The result is a vehicle that remains composed and predictable on the track without compromising cabin comfort during the daily commute.

• DuroBall Technology: Combines spherical bearing precision with polyurethane dampening
• Material: Engineering-grade polyurethane formula resistant to oils, water, and extreme temperatures
• Performance: Reduces deflection and improves steering response and chassis feedback
• Manufacturing: Designed, engineered, and manufactured in Australia

The SuperPro DURO3725K Rear Trailing Arm Forward Bushing Kit provides a significant upgrade over factory rubber and traditional elastomer bushings. Utilizing the innovative DuroBall design, this kit features an isolated spherical bearing encased in a proprietary polyurethane compound. This hybrid construction delivers the precise geometry and friction-free articulation of a spherical joint while maintaining the NVH (Noise, Vibration, and Harshness) mitigation required for daily driving.

By replacing worn OE bushings, the DuroBall system eliminates unwanted deflection that leads to sloppy handling, irregular tire wear, and diminished suspension response. This is particularly critical for vehicles equipped with larger wheels, stickier tires, or upgraded braking systems that place higher loads on suspension pivot points.

• Increased Precision: Spherical bearing design ensures consistent suspension geometry under load.
• NVH Isolation: Bespoke polyurethane casing dampens road noise and vibration.
• Friction-Free Articulation: Allows dampers and springs to operate more effectively through their full range of motion.
• Durability: Engineered to withstand harsh track use and demanding street conditions.
• Part Number: DURO3725K
