Why Won't the Air Lift Ride Control Air Helper Springs Work on 1984 Toyota with Extended Cab?

Hello George,

The Airlift 59502 Ride Control Air Bag Suspension Kit is specifically designed to fit certain trucks based on their frame design, cab type, and bed length. If a product like the # AL59502 "does not work" with an extended cab model, it's usually for a few reasons:

-Frame Differences: Extended cab trucks often have different frame dimensions (length, crossmember location, or frame rail width) compared to regular cab or crew cab versions. The air bag brackets are designed to fit very precisely onto the frame, if the crossmembers or holes are in a different spot, the kit won’t line up correctly.

-Axle and Suspension Variations: Extended cab models might have a slightly different leaf spring design, ride height, or axle setup compared to other cab versions. Airlift kits need very specific mounting points to correctly place the air springs.

-Bed-to-Axle Positioning: The distance from the rear axle to the rear of the cab or bed can vary between models. A kit like the 59502 expects the axle and frame to be a certain way relative to the truck body. If that distance is different, the air bag system might not fit properly without modification.

-OEM Equipment Differences: Some extended cab models have factory components (like auxiliary fuel tanks, spare tire locations, exhaust routing) that can interfere with the installation of an aftermarket air bag kit.

We do have a different solution for your 1984 Toyota Pick-Up with Extended cab, the SumoSprings Custom Helper Springs - Rear Axle # SS89PV, these are rated for 1,800 pounds and are even maintenance free!

What kind of load are you hauling that you need the airbags for?
