The Dobinsons IMS coilovers are one of the best options for the front of the 2005-2021 Nissan Frontier, 2005-2015 Nissan Xterra, and 2005-2012 Nissan Pathfinder. Designed, developed and tested in Australia by Dobinsons Spring & Suspension, in-house suspension design engineers, Dobinsons 4×4 shock absorbers are designed and tested to perform in the harshest conditions right across the world.

As Dobinsons Spring & Suspension export to over 40 countries worldwide from their Australian head office, the importance of quality is at the forefront in the complete design and manufacturing process. This ensures every shock can withstand the blistering heat and corrugations of the Australian outback right through to the subzero temperatures of a Russian winter.

Dobinsons IMS shock absorbers are made from the world’s highest quality external and internal parts sourced worldwide. They provide a significant increase in performance over the standard shock absorbers. Originally equipped shock absorbers are prone to shock fade and when a vehicle is loaded simply cannot cope with the additional weight and the harsh condition that 4X4 owners love to put them through. Dobinsons IMS shock absorbers feature larger bodies, larger bores and increased valving performance to dramatically improve vehicle handling and control and reduces shock fade.

Features:

• Lift Range: 2-3 inches (depending on spring and weight of vehicle)
• Fully re-buildable and re-valvable
• Zero shock fade in all terrains with full load
• Direct, bolt-on replacement for easy fitment
• Corrosion resistant (EDP Surface Protection)
• Heavy duty single piece lower leg
• Enormous oil capacity
• Heavy Duty 3 Stage FKM HNBR Sealing System for the ultimate in reliability
• Race inspired hi-flow CNC 6061 Billet alloy piston 50mm bore – for the ultimate in offroad handling
• 56mm/2.2” Bodied Series

NOTE: This measurement must not be exceeded as this may cause the coil spring to bind and will cause serious damage to the shock absorber, the spring and also the vehicle. A minimum of 50mm of downward wheel travel must always be maintained. When using +220 springs, please install the thicker Navara washer on top of the piston cup that's included with IMS or Twin Tubes to prevent coil bind.

To complete the assembly it's recommended purchase replacement strut mounts. The full IMS Front lift kit for a 3" lift can be found here.

It is also recommended to add Front Upper Control arms that improve clearance around the strut mount on the frame to avoid the Coil Bucket Contact (CBC).  Z1 prefers the SPC Front Upper Control Arm set for it's improved clearance, added adjustment and sealed ball joint. Like most 2014 Frontiers it should be planned to clearance the FUCA mount for install and the lip of the coil bucket may need to be ground off in certain places (this clearance work is standard regardless of brands from our experience and general practice installing lifts over 1").

Fits:

• 2005-2021 Nissan Frontier (D40)
• 2005-2012 Nissan Pathfinder (R51)
