The 44-39420 lift kit utilizes the very best in ReadyLIFT engineering with boxed steel front/rear cross members and full-width front skid plate constructed of thick 3/16-Inch plate steel. New 1/4-inch boxed plate steel differential drop brackets feature a double gusset and boxed center rib to take the abuse of front differential torsional twisting.

Our 4-Inch lift kit features heavy-duty angled and offset top mount strut extensions that realigns the struts to optimize shock performance and minimize wear. A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better handle the larger wheels and tires that will find their way onto this new lifted truck.

To lift the rear, new fabricated steel rear blocks with integrated bump stop landings have been added as well as new rear shock extensions. With months of engineering and development and more awesome features than we could possibly mention, the bottom line is this new Big Lift Kit is the best 4-Inch lift kit you can install on a new body style 2019-2023 GM 1500 4WD truck!

Thousands of miles of road and trail testing have proven our new 4-Inch lift kit makes these new GM 1500 trucks ride better than stock!

Not for super aggressive chewers
Size: Tripod
Had high hopes, but our super-chewer somehow manages to UNSCREW the ends of the toy. Had to throw it out so she wouldn’t choke

Great Chew Toy
Size: Tripod
Has been great for our medium sized dog who loves to chew everything. We didn't realize it makes a sound too, which helps keep his attention. So far it has held up well.

Big and Squeaks and Tough BUT Dog Destroyed it in 3 days!!
Size: Tripod
The pitbull who is an agressive chewer LOVES this and it squeaks! Highly recommend this large sized chew toy. BUT in 3 days the dog destroyed it. It is now in 6 pieces. But it still squeaks. I guess I can't recommend this because it is NOT durable.
