XR Spacers
 

I have one inch spacers in my XR drives now and Julie tells me to go to 2 inch.

Can I buy another one inch kit and stack it on or do I need to buy a 2 inch kit which is more money?

I think in addition to the spacers, I need longer studs and a longer coupler for the drive shaft. How about shift shaft?
Anything else I need?

I'll probably do the labor myself. Any tricks?

Thx - JON

You will need a longer coupler and studs. I wouldn't recommend stacking them. A 2" spacer will be less work and you can sell the 1" spacer or keep it for future testing.

Jnewton,

I have a set of 2" spacers on my boat with 2005 XR drives now, but I might end up going to 3" spacers if they work better for me. If the 3" spacers work for me, my 2" spacers will be for sale.

When will you know? I'm ready soon.

What is your boat that you need 3 inch spacers?

Re: XR Spacers
 

For testing purposes we stack spacers. Of course you have to use the proper studs and coupler. When we figure out what the proper drive height is then the proper spacer is installed. We are also careful to use the appropriate spacer for the application. We recommend certain spacer manufacturers over others for severe duty use, such as racing applications. Some spacers are built better than others and hold up to severe duty better than others. We have had customers lose lowers due to spacer component failure.

I have a Supercharged engine in a 1996 Cobalt 253. Over 600 hp and am able to do 73.5 with a 28p Bravo 1 at 5000 RPM Over 17% slip. Brett Anderson (bblades) says I need more bow lift but I am careful not to drop the cavatiton plate below the bottom. Is this right or can I go lower than 1/2" which makes the cav plate flush?

The Imco spacer I bought came with everything needed to install it except the merc gaskets.
