New Masuma product — Rack End & Tie Rod End sets for European cars.
For most European cars Rack Ends are assembled with Tie Rod Ends. Masuma replicates the corresponding OEM parts packages — you will definitely get a full set of spare parts, not only rack ends or tie rod ends, like many analogues.
Reliable ball joints
Design base of Rack Ends and Tie Rod Ends is ball joints, which provide these parts mobility.
Rack Ends and Tie Rod Ends ball joints are produced on modern undismountable technology. Ball joint studs are made from 40Cr steel with vacuum heat treatment. Mirror treatment of the ball surface provides roughness no more than 0,4 μm, it minimizes friction and guarantees a long service life.
Ball joints are working in spherical bearings of POM 500P polyoxymethylene — durable polymer with smooth surface made by DuPont. Such construction holds the ball stud reliably and provides long service life without beating and backlash.
Durable and elastic dust boots
Dust Boots strongly influence Rack Ends and Tie Rod Ends service life. Masuma Rack Ends and Tie Rod Ends are protected by durable dust boosts, which keep elasticity at a temperature of −40… +80 °C.
In the ball joints inside the dust boots there is a high-quality lithium grease Apolloil Autolex С, which keeps high viscosity even at high temperature and active ball joints work. Grease reduces friction of the ball stud with the polymer bearing and makes the joint hermetic, protects it from wetness and corrosion.
Matching the OEM parts
Rack End & Tie Rod End sets are similar to original OEM parts from European manufacturers that provide Rack Ends in assembly with Tie Rod Ends. Choosing Masuma you are guaranteed to get a full set of parts.
