Default Heater Hose Mod Writeup

A lot of people have been asking about what this mod is. There is no writeup, so id like to explain it step by step. Mods feel free to sticky this if you feel it is explained well enough.

Step 1: Buy heater hose. You will need 3 feet of hose. I used 1/2 inch. You can use 3/4 inch or 5/8 inch, but the 1/2 inch was snug enough for me.

Step 2: Raise the rear of the car. Support the rear with 2 jackstands, letting the rear hang freely.

Step 3: Remove the spring. Compress the spring until you can take it off of it's perch. I was able to do this with my hands. Some people need to unbolt the shocks to take the springs. If this is necessary, a 13/16" socket is needed.

Step 4: Remove rear isolator. The rear isolator is the rubber disc that sits on top of the spring. Set it aside after removing the spring.

Step 5: Cut hose in half. Cut your 3 foot section in half. Use one section for each spring.

Step 6: Place hose on spring. Lubricate the hose/spring lightly with some WD 40 or Fluid film in my case. Coil the hose onto the spring as far as you can. You should have no more than 2 inches of excess hose extending from the edge of the spring. This will insure that there will be no metal to metal contact between the car and spring. Trim off the excess.

Step 7: Reinsert spring. Slide the spring into place until it rests on its perch. Make sure the top is flush with the body. Rebolt the shock if you unbolted it

Repeat for the other side. Then stand back and admire your lower stance! Install time is 30-45 minutes. Average drop is 1/2-3/4 inch. Some people have reported a 1 inch difference. A great mod for a few bucks.

I have lowering springs but can you do us a favor and measure from the ground, across the center cap, to the bottom of the fender and tell us the height? Maybe helpful for people who are curious.

is this mod for stock suspension, or does it work well with aftermarket springs, for instance, i want strano springs but dont know if they compromise for that stock and if i do the mod and strano springs if my back end will be to low?

im sure people have done it with aftermarket, but it is intended for stock springs. i wanted my car lower, but i didnt want to buy new springs. plus with my backseats out, a rake was created from removing the weight. this mod fixed the rake, now it is level

take the top of the spring, and put it through the hose. you are just sliding it over the spring. the hose acts as the isolator. the isolator is about 3/4 to an inch thick, where as the hose is not. so by taking away that gap, you are lowering the car

Because the bare spring on the bare underside of the car would sound very horrible! and a little clunky...

i didnt think it would be this hard to figure out but this is the best explanation i have. the spring makes a coil. the coil stops at the top. you slide the spring into the hose and make it coil around. if you still cant see that, make a circle with your thumb and index finger. now stick your other index finger through the hole you just made. imagine the hole as the hose and your finger as the spring. the hose covers the outside of the spring and acts as the insulator

personally i didnt need to use one, i could get them out with my hands. most people have done the same. at worst you will have to take the bottom bolt off of the shock so the rear can hang more and the springs should pop right out

the rear usually (99.999% of the time) do not need any compression. If you jack up the car, they will 50% of the time fall right out. The other 50% of the time, disconnect the shocks from the rear axle and then they fall out. . . .
