MRA 3 Way Adjustable Shock Absorbers

Built on the back of the race winning Monotube Remote Reservoir (MRR) shock absorbers, Dobinsons new range of MRR Adjustable shock absorbers combine the best in high performance race-bred Monotube technology, with an all new 3-way damping adjustment system to turn your 4x4 into the ultimate off-road machine. Each component of the MRR shock absorber has been refined and improved to offer a higher level of ride quality, vehicle control and shock absorber performance.

The new 6063 honed aluminium reservoir, revised light-weight floating piston, Carbon Fibre/PTFE/Disulphide composite wear band, improved 3-stage sealing system and the ability to run lower gas pressure with the addition of the reservoir compression adjuster, have combined to provide massive reductions in shock absorber friction, resulting in an improved vehicle ride and damping performance. The revised sealing design now provides a 3 stage FKM-HNBR shaft seal system that, when combined with the reduced operating frictions, provides a vastly increased service life with reduced wear.

The Micro-polished, hard chromed and heat treated shock shaft, revised CNC aluminium high flow race piston, and DOM Seamless tubing body provides the ultimate in performance and off-road durability. The 3-way adjustment design reduces the main piston working load, distributing heat more evenly between the main piston and the reservoir piston for reduced operating temperatures, and allows quick and easy damping changes for the ultimate in shock tunability in varying terrain and vehicle loads, to keep you controlled and comfortable. Enjoy the ride...

Important Notes for setting up your Vehicle Correctly:

  • When selecting Springs to suit your lift, please Select Springs only to suit Current "CONSTANT" Loads Front and Rear.
  • Towing Loads are not included in your Constant Load Calculations, as they are not "Constant" Loads.
  • Please do not put Occasional Loads into your "Constant" Load determinations.
  • Selecting a load rating that is too heavy for your setup will result in Poor Flex Off-Road, Compromised Suspension Travel & Rough Ride, and will cause damage to your new shock absorbers and other components by pushing them outside of their intended range.

Please Note:

  • All lift heights stated are estimated lift heights, due to the large number of variables in each different vehicles setup and accessories.
