Des Sol 50mm Suspension Lift Kit Facts

Overview

A well designed, hard wearing suspension is critical for high performance 4×4 vehicles. The Suzuki Jimny is a fantastic little 4×4 vehicle with amazing off road capabilities. Des Sol engineers realised that this presented a great opportunity to extend the performance of the Jimny and design a 50mm Lift Kit that would be affordable for the majority of South African Jimny owners.

Coil Spring Manufacture

Compared to hot-rolled steel, cold-rolled steel has a nearly 20% increase in strength through the use of strain hardening. It’s through a series of breakdown, semi-finishing, sizing, semi-roughing, roughing, and finishing that cold-rolled steel shapes can be created.

Some coil spring manufacturing companies in South Africa use a hot rolled process and locally produced steel. Des-Sol uses a spring manufacturing company that imports their steel which is cold drawn. These coils are then cold rolled shot peened, load tested, triple scragged and load tested again.

• Shot peening has proven capable of increasing spring operating life by five to 10 times or more when compared to unpeened springs.
• Scragging is a process where the spring is pressed to its solid height. Once the spring is taken to solid, it will be able to operate at a higher load capacity without overstressing.

Des Sol Engineers have ensured that our coil springs are manufactured in accordance with ISO 9001:2015 and certified by the German TUV authority (Certificate Register. No. 01 100 928822). Des Sol are also in the process of obtaining IATF 16949 certification for their coil spring manufacturing process as well.

IATF 16949:2016 is the International Standard for Automotive Quality Management Systems. IATF 16949 was jointly developed by The International Automotive Task Force (IATF) members and submitted to the International Organization for Standardization (ISO) for approval and publication.
