RH 5/8in Adjuster

The ALLSTAR PERFORMANCE RH 5/8in Adjuster (SKU: ALL 56198) is a precision linkage adjuster engineered for suspension tuning and drivetrain alignment applications. This right-hand threaded component allows technicians and fabricators to fine-tune rod length in critical systems where exact positioning is essential for optimal performance. Whether you're building a custom chassis, adjusting suspension geometry, or aligning transmission linkage, this adjuster delivers the repeatability and durability required in both street and competition environments.

Constructed from hardened steel with a black oxide finish, the RH 5/8in Adjuster features a 5/8-18 right-hand male thread on one end and a 5/8-18 left-hand female thread on the opposite end. This dual-thread design enables smooth, controlled adjustment without the need for additional fasteners or adapters—simply rotate the body to lengthen or shorten the assembly with precision. The black oxide coating provides corrosion resistance suitable for underbody and engine bay environments, while the robust steel construction ensures longevity under load and repeated adjustment cycles.

This adjuster is ideal for drag racing, road course, and custom automotive builds where suspension tuning and linkage geometry demand accuracy. Fabricators and performance shops rely on components like the RH 5/8in Adjuster to achieve repeatable results and maintain critical clearances. The compact design (4 x 1.1 x 7.05 inches) fits tight engine bays and frame rails, making it suitable for both original equipment applications and aftermarket performance systems that require precise rod-end positioning.
