Öhlins LMJ series Adjustable models

The Öhlins LMJ stock car shock absorbers are based on the race proven Öhlins type 46HRC, a shock absorber with a large reservoir, mounted by a hose (H) features separate rebound (R) and compression damping (C) adjusters. The large shock absorber reservoir, connected to the shock absorber body by a hose contributes to the improved cooling. The reservoir contains the floating piston and the gas that pressurizes the damping fluid.

Designed for classes like Late Model, Dirt Modified and Sprintcar
Lightweight aluminum body
Large reservoir for better cooling
2-way adjustable damping
Quick response for best handling
Optimum consistency on long runs
Easy to dial-in, reshim, rebuild and service
Professional technical support

WCJ, MCJ, STJ, LMJ Öhlins Design

The Öhlins WCJ, MCJ, STJ and LMJ are all based on Öhlins successful application of the ”de Carbon” concept that has won more than 60 World Championship titles.
The de Carbon concept; the damping fluid placed under pressure by gas and separated from the gas by a floating piston, has several advantages (fig. A). It prevents the risk of cavitation, that can wear out internal components and cause inconsistent damping, and it eliminates aeration of the damping fluid, which also causes inconsistent damping. It improves the cooling, because the fluid is in direct contact with the outer tubing. It gives more consistent damping, regardless of the shock absorber’s working temperature, and it makes the shock absorber last longer.

The main piston (fig. B), is specially developed for oval track racing. Thanks to the shape of the apertures in the piston the damping force builds up rapidly. The result is excellent short stroke/high force performance. The internal pressure is balanced to cope with temperature build up and to prevent any chance of cavitaion, yet reducing the fluid compressibility and the friction from the pistons and the shaft seal. The new Öhlins shock absorbers are built to perform and endure. They are easy to set up and to sort out. Thanks to the design of the main body they are also easy to maintain and to rebuild. All Öhlins shock absorbers are built with a desire to win and with precision that ends up in quality, a quality you can see and feel.
