Dayton RB-172 Details

Customer Q&A - Dayton RB-172

Will this fit the rear leaf spring eye hole on a 2000 chevy silverado, 5.3 extended cab, 4x4...

The RB-172 is the correct rear bushing for the leaf spring of a 2000 Chevrolet Silverado 4x4.

Will this fit 2003 GMC Sierra 1500 4wd

These bushings were used in the rear position of the rear leaf springs on a 2003 GMC Sierra 1500 4x4.

I've got a 1995 chevy c1500 2wd. Is this the correct bushing for front and rear eyes of the leaf springs? Or are they different part numbers? What about the shackles?

The bushings, RB-172, are the same for both ends of the springs. They use a 9/16 x 4-1/2" bolt (C916412, SLN912 is the nut) in both ends of the springs and also the shackle. The shackle used for this application is E831-22.

I have a 2001 Chevy blazer 2wd ls. I need leaf spring bushings for the front and rear. Not shackle bushings. Do you have an accurate part number for the parts I need because no one has been able to help me so far.

From 1995-2005 the S-10 Blazer 2WD and 4X4 uses an RB-231 for the front spring eye and an RB-172 for the rear spring eye.

Will this bushing work on an 05 Colorado too

Yes, the 2005 Colorado uses bushing RB-172 in both the front and rear of the leaf spring.

Will this fit the FRONT leaf springs of a 1996 Chevrolet Express 1500 5.0L with the tapered 3 leaf spring?

The RB-172 is used in both the front and the rear of the rear leaf springs for the 1996 Express vans. We are showing coil springs for the front suspension.

Will this work for a 2007 Colorado Crew cab as well?

We are showing that all the 2007 Colorado pickups all use the RB-172 bushing for the front and rear of the leaf spring.
