Combination Kit of Competition Style Motor Mounts for 73-91 GM with Small Block High Clearance Engine Crossmember
Combination Kit of Competition Style Motor Mounts for 73-87 GM with Small Block High Clearance Engine Crossmember
Our small block version crossmember offers greater clearance to the front axle for suspension travel, but tucks up tighter to the engine. This is recommended for low lift/long travel suspensions. If that's not a concern, the big block version crossmember offers ~3/4" more oil pan clearance (and can be used with a small block).
Requires at least 2" suspension lift for clearance to front differential.
We are working with a second generation Kevlar reinforced polyurethane bushing material that is proving to be another step stronger and more durable. At this time the new material is only available in the same grey color as our Kevlar tierod end boots. For more information on bushing color, click here.

When installing make sure the the center to center bolt spacing that is 26.75" should be facing towards the radiator. In other words the cross member taper should be narrower towards the front of the vehicle.
On "LS" Applications the small block crossmember can be used to get more uptravel if you are using an aftermarket oil pan like the Tilden Motorsports one.
People have asked what it takes to put one of these crossmembers in a 67-72 GM truck/SUV. By using the wedge shape "saddles" that the motor mounts bolt to on a 73-87(91) GM truck/SUV you can use our crossmember in the earlier frame. It does take some drilling/fitting to put them in.
Here are some pictures of our crossmember in the earlier frame:
To help with deciding if the small block crossmember will work with your oil pan here are some measurements to check:
Small block crossmember is ~1-3/4” at front, 2-1/4” at back, from bottom of frame to top of tube.
