Heavy Duty Titanium Turnbuckles
The XB2 now features ultra-lightweight & strong titanium turnbuckles all made in-house in Europe. The titanium turnbuckles enhance performance in all conditions.
The turnbuckles are very durable thanks to their heavy-duty design and the premium titanium materials.
The 3.5mm heavy duty turnbuckles together with the 5.4mm heavy duty ball joints create super strong and reliable steering & camber links. The composite ball joint design reduces bind for smooth suspension and steering movement.
Increasing the ball joint size from 4.9mm to 5.4mm created smoother and more reliable suspension linkages. There are two different ball cup shapes used in the XB2; one straight and one curved for improved clearance around the front wheel. Each ball joint is slightly longer compared to the 4.9mm counterpart so the new 3.5mm Ti turnbuckles thread deeper in the ball cup to improve reliability and prevent deformation of the ball cup at the weakest point at the end of the turnbuckle threads.
The 5.4mm ball ends’ height was increased by 1.0mm to improve the range of motion of the joint. The complete 5.4mm assembly is smoother, more reliable and less likely to pop off.
