Torsion Bar Bushing

The torsion bar bushing installs at the ends or middle support points of the torsion bar. This part handles the twisting stress from the torsion bar during driving. It also reduces vibration transfer from rough roads. Our product uses high-torsion natural rubber. Precision-machined metal inner and outer tubes bond to the rubber through high-pressure vulcanization. This structure allows the product to keep excellent rebound properties and strong bond strength even after repeated twisting. This product fits passenger cars, SUVs, and commercial vehicles. It is a direct replacement for factory parts.

The torsion bar bushing must handle high-intensity twisting loads in real-world use. We added anti-tear agents to the rubber compound to improve tear resistance. We also optimized the metal tube surface treatment. Our product remains structurally intact after over one million twisting cycles. Our technical team has over 6 years of experience in product development. We have successfully developed over 30 different specifications. We supply this product to Anhui Zhongding and ASIMCO. Annual capacity exceeds 25,000 pieces.

Our torsion bar bushing withstands over 1 million torsional fatigue cycles under standard test conditions. It shows no bond failure or visible cracks. Need a specific stiffness curve? Our technical team can adjust the rubber formula and structural design. We can achieve linear or non-linear stiffness curves based on your vehicle parameters and operating conditions. Custom product sizes are also available. First articles are ready in 15 to 20 days. We support small trial orders. Packaging can be neutral or branded. Shipping is FOB Ningbo or Shanghai. Delivery takes 20 to 30 days after order confirmation.
