    The 2013 Tacoma outfitted for off-road patrol has come full circle and found its way back into my fleet. After 175k miles of hard use, the rear leaf springs seem toast, completely flat when unloaded. Upgrade/lift replacements are off the table because it's a State rig. Has anyone used Sumo Springs for the specific intent of improved rear handling when off-roading? That seems to be the most cost effective option for a vehicle that likely won't be in service for much more than another year or two.

    Not sure I’d want them on an off-road rig.
    They would likely prohibit you from getting your full range of up travel.

    SS are designed to help prevent sagging when towing or carrying a heavy load in the bed. As @TnShooter said, "They would likely prohibit you from getting your full range of up travel". In essence, they're like tall bump stop. I have them on my rig, but I'm not out 4 wheeling. Forest service roads are about the extent my off-roading. From there it's dirt bikes.

    From what little I know, Timbren are shorter than the SS. Both have a progressive design, with the SS being a little more progressive or softer. I bought a set of used "blue" SS on this site a few years ago and they have worked out very well for my use.

    The Timbren, being shorter and stiffer could help with your situation of the rig being state owned and not wanting to shell out cash on something that's only going to be in service another year or so.

    Hopefully you'll get some input for someone that has first hand experience. ​

    I found a couple of pictures that might give you an idea of the difference between stock bump stop and a SS. They are both of my rig showing the stock bump stop, right after the recall leaf springs were put on my truck and one of the blue SS when I was installing them.

    get the sumosprings meant for the 3rd gen SSR-612-40's they are 1in shorter and 1in less in diameter than "the ones meant for the 2nd gens - 610-40's" The 610's are also specd for the latest tundra so they are WAY too big for a 2nd gen or 3rd gen taco IMO.

    Just put a set of 612's on my 2nd gen. Work great and I dont think there will be any issue with limited uptravel.

    Also, you are allowed to replace a bump stop, why not get some 3rd gen take off leaf springs and swap em in. They are an OEM toyota part that should have a lil more life in them.

    +1 for the 3rd gen OEM takeoff springs. I don't think that any bumpstop will be able to completely mask a worn out set of springs.

    I have a set of Wheeler's superbumps and they seem to be a little more squishy than some of the other options. Combined with a new leaf pack the Superbumps are much better than the worn out OEM springs.

    Unless I pay for it out of pocket, I can't buy from someone who isn't an approved State vendor. I may look into a set of new 3rd gen springs, though.

    Ended up going with the Timbren off road bump stops. They are not night and day difference like some reviews claimed, but they are definitely an improvement over the factory pyramid style. I expect they'll soften up a bit over time, improving the jounce response even more.

    Given your situation these seem worth looking into

    https://www.perryparts.com/product-page/1-pair-aerobumps-ab3f-rear-bumpstops

    new company. Maybe you can do a review. Buying the required brackets will probably be cheap.

    there is also Archive who until now claimed to be the best. But it costs more, which is a factor in your truck being fleet and not personal



    for fronts I ordered Perry Parts ones to try and will probably do a review.
    Rears I am undecided and may put off to later as 1.they cost more, 2.I don’t wheel that often 3.my used Op3 RXT leafpack is still springy

    but yes last trail I did when the wheel flexed up the tire got really close to the fender
