Dobinsons - 1.0-3.5" MRR 3-Way Adjustable Lift Kit Toyota 4Runner 4x4 2003-2009
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...

- ***2.5" or more of lift, new UCA's are recommended***
****Coil seat for IMS59-50220 should be set at 226mm(8.83") for 3 inches of lift, for 2 inches of lift the coil seat should be set at 213mm(8.38") from the strut bushing eye. Picture black and white on the listing is to reference how to measure. Please check our instructions section or reach out if you have any questions. If done incorrectly you can damage the shocks, springs and vehicle.*****
NOTE: For a lift of 3" in the rear, new extended brake lines and minimum of 2" bump stop extensions are required to be used with our long travel rear shocks. At full extension, the stock brake lines could get damaged, and with stock bump stops in place, the shocks will bottom out before the bump stop fully engages, which will quickly destroy the shocks.
