KDS

These brackets were specifically designed for the 1994-1996 GM B-Bodys. They provide a bolt-in installation for any 1994-1996 Caprice, Impala SS, Roadmaster or Fleetwood Brougham Sedans, as well as the Chevrolet/Buick wagons of the same era. Direct fit design.

Brackets are bare steel, photograph shows black powder coat which is not included.

Simply bolt KDS brackets to your LS engine, and lower the engine into the car. The right side bracket accomodates the rear-set mount cushion that is specific to the LT1/L99-era cars.

KDS brackets fit using the OEM installation locators. They locate the LS engine in the same place as the 5.7L LT1 or 4.3L L99 used to fit. You maintain your transmission location, and driveshaft. You can reuse your existing 4L60E transmission. Even if you have modified your car with any of the aftermarket B Body transmission crossmembers, you can retain the parts you already have.

Maintain driveline angles. KDS competitors change the driveline angle by as much as 2 degrees, but do not tell you that.

KDS mount brackets use the OEM frame mount isolators. Some competitors use re-purposed control arm bushings!!??
Installation Notes:

KDS mounts are a great match for the GM 1998-2002 Camaro/Firebird (aka F-body) LS1 oilpans. These pans are still available new from GM Performance Parts dealers Be sure to order the oil pickup tube and the dipstick and dipstick tube in order to have a complete kit.

The Holley LS Swap oilpan is another suitable option, PN 302-2. This pan is a very close replica of the GM LS1 Camaro/Firebird oilpan.
*** The GM Musclecar pan is a very deep pan, and will hang 2-1/8″ below the engine crossmember. While it will physically clear the engine crossmember, the bottom of the pan is unprotected if you encounter a deep pothole or a “whoop” in the road where the suspension bottoms out. What’s a whoop?… They are the dips in the road with all the gouges in the pavement from other cars bottoming out. For this reason, KDS does not recommend the use of this pan, ultimately it is your choice.

Headers/Manifolds KDS customers have reported good fitment with various headers made for 98-02 LS1 F-bodies. Minor trimming to the engine crossmember braces may be required, but these braces do NOT have to be removed completely. If you are on a budget, or want a more stock appearance, 2010+ Camaro manifolds, 2008 G8 manifolds and 2004-2009 V8 Trailblazer/Envoy/Rainier/Saab 9-7x manifolds are a good fit with good frame clearance.

KDS Performance Mount Brackets allow a direct mounting option for LS engine retrofits in vehicles originally equipped with a Small Block Chevy.

Brackets are bare steel, photograph shows black powder coat which is not included.

KDS Performance Motor Mount Brackets have been successfully used on:

1973-87 GM Full Size Trucks (Blazer/Silverado/Suburban etc).
1988-98 GM Fullsize pickups. Includes 1999 Tahoe/Yukon/Suburban, and 2000 2500/3500 trucks with the 5.7L/350ci Vortec engines
1977-1993 GM Fullsize “B Body” cars
1978-1987 A body and G-body
KDS brackets locate the LS engine at the “stock” SBC location, ie, the new LS engine does not require any relocation of the transmission. This has several advantages:

Reuse your existing transmission
On 4WD trucks, you don’t need to move your trans, transfer case, or modify 2 (!!) driveshafts.
You can reuse the stock fan shroud and still run an LS mechanical fan with no fitment issues.
Maintain the stock driveline angles. No chasing driveline vibrations because of odd driveline angles from poor motor mount bracket design.
Instead of using adapter plates, KDS motor mount brackets incorporate the clamshell mounting features into the bracket.
With your order, you will receive
