QA1 DK31-GMG2 Level 1 Drag Kit W/O Shocks for 1969-1972 GM G-Body

Vehicle Fitment

• 1969-1972 Pontiac Grand Prix (GM G-Body, RWD; small-block and LS-powered configurations)
• 1970-1972 Chevrolet Monte Carlo (GM G-Body, RWD; small-block and LS-powered configurations)

Fitment Notes

• Level 1 full-vehicle drag suspension kit for 1969-1972 GM G-Body applications.
• QA1 specifically identifies Grand Prix and Monte Carlo as the primary applications for this kit.
• Designed for rear-wheel-drive (RWD) vehicles.
• QA1 states the drag kits are geared toward average-weight, stock-trim vehicles using small-block or LS-powered combinations.
• This is the W/O Shocks configuration; shocks are not included.
• Because shocks are not included, springs and thrust-bearing kits are also not included.
• Designed for bolt-in installation and intended to work with the OE components to which the supplied parts attach.
• The kit can be installed in stages using compatible QA1 components as the vehicle is developed.
• 1968 and earlier GM A-Body applications are excluded; they require a different QA1 application.
• 1978-1988 GM G-Body applications are excluded from this specific 1969-1972 kit.
• No 2026 fitment is applicable because the specified GM G-Body applications ended before 2026.

Features

• Level 1 full-vehicle drag suspension package for early GM G-Body vehicles.
• Engineered to improve launch performance and straight-line stability.
• Designed to improve consistency during drag-racing launches.
• Rear sway bar improves rear chassis control during acceleration and transitional maneuvers.
• Boxed lower trailing arms provide increased rigidity compared with factory-style components.
• Adjustable upper trailing arms allow rear suspension geometry to be tuned.
• Fixed tubular frame braces add structural support to the chassis.
• Anti-hop bars help control rear axle wind-up during hard acceleration.
• Tie-rod adjuster sleeves provide adjustment capability for compatible steering components.
• Components are selected as a coordinated drag-racing suspension package.
• Bolt-in design minimizes the need for fabrication when installed on the intended chassis.
• Allows the vehicle to be upgraded in stages using the QA1 component system.
• W/O Shocks configuration allows the builder to select dampers and spring rates appropriate for the vehicle's actual weight.
• Designed around average-weight, stock-trim small-block and LS-powered vehicles.

Product Description

QA1 DK31-GMG2 is a Level 1 full-vehicle drag suspension kit designed for 1969-1972 GM G-Body vehicles, including Pontiac Grand Prix and Chevrolet Monte Carlo applications. The package is engineered to improve launch performance, straight-line stability, and consistency by upgrading key suspension components that influence rear axle control and chassis behavior during hard acceleration.

The kit combines a rear sway bar, boxed lower trailing arms, adjustable upper trailing arms, fixed tubular frame braces, anti-hop bars, and tie-rod adjuster sleeves. The adjustable rear suspension components provide greater control over suspension geometry, while the anti-hop bars help limit rear axle wind-up during aggressive launches. The components are designed for bolt-in installation and to work with the OE components to which they attach.

DK31-GMG2 is specifically the W/O Shocks version. QA1 states that kits ordered without shocks also do not include springs or thrust-bearing kits, allowing the builder to select damping and spring rates based on the vehicle's actual weight and setup. The kit is intended for rear-wheel-drive, average-weight, stock-trim vehicles using small-block or LS-powered combinations and provides a staged upgrade path for drag-oriented GM G-Body builds.
