*** FYI - Radflo is running 2 weeks on Coilovers & Shocks currently. *** 

This variation of the 1.2 kit upgrades the shocks to 2.5 with External Reservoirs. This would be ideal for extended high-speed travel in Baja California, Rock Crawling slow or another similar terrain. Also for people who just want the best money can possibly buy.

The reservoir places the air bubble at the end of the reservoir, versus the top of the IFP shock. By placing the air bubble at the end of the reservoir you will get a 100% consistent stroke the entire length of travel. With an IFP shock, which this kit does not include, you will gain spring rate as the shaft travels upward compressing the air bubble. This is the benefit of a reservoir shock. It has nothing to do with going fast or heat. See the Photo below.  We do not offer an internal bladder shock. 

The shocks in this kit are the Remote Piston Reservoir.

 The kit with the best "Pure Off-Road Prowess Bar None".

Adjustable 1.5"-3.5" Front & 3.5-4.5" Rear. Lift height depends on model year.

4WD Only.

This kit modernizes the 3rd Gen 4Runner. The 4th Gen 4Runner 2003-2009 was 2" higher in the rear than the front to combat sagging. The 5th Gen 4Runner is as well, 2" higher in the rear then the front, like a pickup truck. These vehicles were made by Toyota this way. The 1.2 kit will build a 3rd Gen 4Runner with a rear that is 1.5" higher in the rear for cargo carrying capability without sagging. This kit can be run on a bone stock truck or on a vehicle with custom bumpers. The kit is adjustable with out buying new parts to accommodate the changes.

The rear coils are brand new, the are made of a small diameter wire with wide wraps. They will require some time to settle to the final height. All of the data for this lift kit was compiled with springs that had between 40K and 100K miles on them. These coils will hold out for an extremely long time, but are tall when brand new, plan on some settling after install. This is not the case with the front coils, those consist of a large diameter wire with tight wraps, they will not change after install.

Turn around 2-4 weeks depending on how fast the front and rear "Hand Made" shocks are assembled.  The time of year can vary production times for Radflo as well.

If your vehicle exceeds the GVWR of a 3rd Gen 4Runner which is 5250 lbs. we do not have a product for you, this kit will not work for you. The curb weight of a 3rd Gen 4Runner is 3600 lbs. Curb Weight and GVWR are not the same thing.

2.5 Size Coil Overs = 3.0" ID Coil in 600, 650 or 700#, Standard or Extended, Extended is 1" more droop over Standard. Compression is the same on both. Extended requires an aftermarket UCA. Standard is for a stock Toyota UCA. (This unit is ideal for a truck that carries extra wight, like a custom front bumper, winch and skids)

What does the 600, 650 and 700 mean? That is how much weight that it takes to push the coil down 1". The larger the coils ID (Inside Diameter) the easier it can hold the weight.

Standard or Extended length is available for the front coils overs, the cost is the same. Standard you can run a stock UCA, Extended you will need an aftermarket UCA.
