QA1 XMR4-5S X Series Alloy Rod End 1/4in Bore 5/16-24 RH Male Thread PTFE Lined with Stud

The QA1 XMR4-5S is a high-performance X Series (Endura) alloy loader slot rod end featuring a 1/4 in. bore and a 5/16-24 right-hand male thread. Designed for demanding racing and performance suspension applications, this rod end delivers exceptional strength and long-lasting reliability in both high-shock and low-load conditions.

QA1's XM Series uses a unique loader slot construction in which the ball is inserted into a machined groove in the body and a Nylon 12/PTFE material is injection-molded in place. This creates a completely self-sealing and self-lubricating race that effectively blocks dirt and debris while eliminating the need for periodic greasing.

Key Features:

• Ball: 52100 bearing steel — heat treated, precision ground, and hard chrome plated for maximum wear resistance
• Race: Reinforced Nylon 12 with self-lubricating PTFE liner — self-sealing and maintenance-free
• Body: Heat treated alloy/chromoly steel with a protective coating for corrosion resistance
• Metal-to-metal support for heavy shock loads with smooth operation under lighter loads
• Increased cross-sectional thickness for greater tensile strength
• 1/4 in. bore with a 1/2 in. diameter ball and 8,452 lb load capacity
• 5/16-24 right-hand male thread with pre-attached stud for easy installation and higher misalignment than bolt-mounted alternatives
• 2-piece construction; sold individually
• Available in right-hand (XMR4-5S) and left-hand (XML4-5S) thread configurations

The QA1 XMR4-5S rod end is widely used in 4-link and ladder bar suspensions, custom steering linkages, and other high-performance chassis applications where strength, precision, and durability are critical.
