1996-2007 GM Truck Gears & Install Kits

For quicker acceleration and maximum power through the entire RPM range, install gears in a lower ratio than stock. Vehicles from the factory come equipped with gears that are engineered for fuel economy, not power. This inexpensive modification will help you put the rubber to the street!

Gears must be closely matched to engine combination; if you are unsure of which gears to order, please call or e-mail.

Motive Performance Gears, specializing in performance differential components for street, stock car, and strip-use, has as an excellent reputation for quality gears in a wide range of ratios to meet your needs.

Ratech, a leading manufacturer of race-proven small rear end parts, has several installation kits available for no-hassle gear installs or assembly of your rear end.

• Basic Kit: Includes pinion shims, crush sleeve, pinion seal & cover gasket
• Complete Kit: Includes pinion shims, carrier shims, crush sleeve, pinion seal, pinion nut, ring gear bolts, cover gasket, and pinion & carrier bearings
• Deluxe Kit: Includes pinion shims, carrier shims, crush sleeve, pinion seal, pinion nut, ring gear bolts, cover gasket, pinion & carrier bearings, PLUS wheel bearings and seals. (All of the small parts and pieces necessary to RESTORE an axle to like new condition!)

Ratech also manufacturs solid pinion bearing spacers, or "crush collars." These are excellent for cars that "shock" their rear ends extremely hard during launching, which is common with manual transmissions. The solid pinion spacer will allow your rear end setup to remain constant after repeated hard launches. (Because this piece is setup slightly different than a standard crush collar, please ensure that your gear installer is familiar with installing solid pinion spacers.)
