Silvers NEOMAX coilovers for the 2001-2011 Mercedes-Benz SL-Class 2WD (R230) are perfect for street driving, and still out perform most on the track. Silvers NEOMAX coilovers are a mono-tube shock design that are fully height adjustable, and come with an 18 month limited manufacturer's warranty.

Features

  • Adjustable T6 6061 front camber plates standard on all applicable McPherson style applications.
  • Koyo Japan Radial Bearing upper spring perch standard on all applicable McPherson style applications. This eliminates spring bind, noise, and gives improved driver feedback.
  • 24 levels of dampening adjustment, combined with our high grade shock oil. Not only do you feel the click in your fingers, you feel every dampening adjustment in the driver's seat.
  • High strength JIS G3445-STKM13C (DIN2393-ST44-2) carbon steel 52mm diameter seamless shock tube.
  • 44mm piston with digressive style valving characteristics provides maximum low speed damping response for ultimate performance while simultaneously giving a comfortable ride.
  • Mono-tube shock design: Increases shock oil capacity as well as displacement over twin tube designs for maximum performance.
  • High viscosity IP F.A. 5W damper oil ensures the best efficiency of shock-absorption and damping control.
  • Height adjustment is provided by the lower bracket which prevents the need to adjust the spring perch or pre-load, offering the maximum possible travel regardless of height setting.
  • Cold-bent springs made from high strength SAE9254 steel which keeps stable elastic modulus.
  • Powder coated steel lower brackets matching all factory brake line and ABS wire tabs for ease of installation.
  • Anodized T6 6061 aluminum lower mounts for multi-link suspension systems to lower unsprung weight.
  • 18 month limited manufacturer's warranty.

Adjustable Camber Plates

Our camber plates are made from T6 6061 Aluminum and are protected by an anodized finish. They come standard on the front of any McPherson style strut application and are designed to offer up to 3 degrees of camber adjustment at any ride height to dial in your alignment.

Pillowball Top Mounts

Our pillowball mounts are comprised of two main parts: A SUJ2 Steel bearing, and a Chromoly Steel 2 piece case. Pillowball mounts provide bind free operation and precise feedback to the driver.

Fully Height Adjustable

Our coilovers are fully height adjustable via the lower mount with no need to change pre-load and sacrifice shock stroke. Simply loosening the lower locking ring and rotating the entire coilover, you will be able to easily fine tune your ride height or weight distribution for corner balancing on track applications.

OEM Fit Steel Lower Mounts

Our steel lower mounts are engineered extensively for strength with key areas reinforced. They are designed with all of the features of the OEM system to be sure every brake line and ABS sensor harness is securely mounted. This keeps installation simple and straight forward.

Aluminum Lower Brackets

T6 6061 Aluminum lower mounts are used on multi-link suspension setups. These are CAD designed to ensure OEM fitment and are lighter than steel components which also help reduce unsprung weight.

Carbon Steel Shock Body

Our shock bodies are made from ultra high strength JIS G3445-STKM13C(DIN2393-ST44-2) carbon steel and are electroless nickel plated for resistance to corrosion and fatigue in harsh climates.

Linear Piston Design

We use a 44mm Linear type piston in our shocks. This style piston gives both excellent track benefits as well as maintains ride quality. Every single shock is hand assembled, and dyno-tested to insure dampening and compression valving is within 5% variation from side to side. There is no random inspection or tests, every single shock is dyno-tested. In the event the shock fails, the internals are discarded and it goes back to the assembly room.

Large Hardened Steel Shafts

We use the largest diameter necessary hardened steel with chrome plating for our piston shafts. With extensive research and development we have the perfect material and diameter needed to have the proper strength necessary to retain lateral rigidity and not bend or bind under heavy loads, which leads to premature wear and lowering piston travel. This provides the perfect combination of strength and weight savings.

Unique Locking Collars

Our locking collars have a specific unique design compared to the other brands on the market. They perform the same as any other locking collar, though with the lower spring perch having dimples instead of slots you do not have to worry about the top spanner wrench slipping and sliding up or down the perch when making necessary adjustments. This make adjusting the pre-load much less of a balancing act, leading to quicker and easier installation.

Optional Radial Bearings

Made from T6 6061 Aluminum using the best Koyo Japan bearings, our Radial Bearing upper perch (McPherson applications only) allows the springs to twist freely as they are compressed. As a spring compresses it may twist slightly which can produce a small noise as if the springs are binding. The same noise also occurs on McPherson applications when the wheel is turned and the spring binds. Radial bearing upper perches will allow the piston shaft and tophat to rotate separately from the spring and shock body allowing for a smoother and quieter rotation.

Rear Adjustment Extenders

Certain vehicles require some interior panels to be removed in order to reach the dampening adjusters. The dampening adjuster extensions can be used to relocate the adjustment knob to a easily reachable location for those quick on the fly adjustments.
