SEAT SUSPENSION JOHN DEERE Z TRAK DESCRIPTION THIS IS A ULTRA LOW PROFILE MECHANICAL SUSPENSION. If your equipment has no suspension now and you are tired of the rough ride and aching back then this is for you. Ultra Low Profile Mechanical Suspension Ultra Low Profile Suspension Seat Suspension for 737 & 757 Mid-Mount Z-Trak 777 & 797 Max-Frame Z-Trak 997 Mid-Mount Z-Trak Professional Z-Traks Z810A               Z820A Z830A Z840A               Z850A Z860A Replaces TCA15602 The 2 common questions about this seat suspension is: Does it fit my Z trak without modifications?  Z-traks have several seats...This suspension fits between the seat and the slide tracks the common holes used to mount this to any seat are at 10.69 to 11.25 (slotted) wide by 11.5 front to back or 9.5 wide by 11.5 front to back. Note: that many slide tracks mount to seat at 11.5 inches but to mount the bottom of the slide track to the equipment is normally 11.0 inches front to back...so don't confuse the 2 measurements when checking to see if it will fit yours...and yes if your seat has that mounting the suspension will fit without modifying. If your seat mounting is different...let us know as we may have a solution. Secondly...others offer this in a kit with more parts and for about 50% more in price...and what you get is 2 plates to raise your steering sticks 2-3 inches and some spring plate which I don't think does a thing for you...we can provide the complete kit if requested, or if you want plates and bolts to raise the sticks contact us. Note: drawing below is showing a kit this listing is for the suspension only.
