Hi,

Spoke with Timbren rep today.
The AWD Astro front PN is GM FAST4.
It is 2 3/4" tall. The pair of Timbrens together has 1300 lbs total spring rate.
So 650 lbs per side . This should help with the winch and heavy brush guard.
The 2 wheel drive Astro with front coil spring can be fitted with TBI GMFAST which is 4 " tall and has total weight rating of 2400 lbs, which is 1200 per side.

Howdy,

I ordered the front Timbrens from Summit Racing for my 2003 AWD Astro.

Howdy,

1. Still waiting for delivery date on the AWD front Timbrens, PN GMFAST4.

2. Rear parking brake adjustment on 2003 with rear disc. Adjusting the cable turn buckle does not hold the tension. Most You Tube Videos show pull rear wheels and caliper and rotor and adjusting the inner wheel to expand brake shows. Next weekend project.

3.. even though cables have stretched, why change them? Just do adjust at wheels.
