Leaf springs do quiet, unglamorous work, locating the rear axle, supporting the weight of the car, and absorbing the road inputs that would otherwise be felt as harshness in the cabin. Decades of use compress and crystallise the steel, eyes wear, and centre bolts loosen. The result is a car that sits low at the rear, rides poorly, and steers nervously over uneven surfaces. The Q Parts standard leaf spring range returns the rear suspension to the geometry and behaviour the chassis was designed around.
Multi-Leaf Construction
Q Parts standard springs use a multi-leaf, interleaved construction following the original specification but produced to a tighter standard. The leaves are spring-grade steel with a consistent heat-treatment profile, so the rate of the spring is repeatable from one assembly to the next and across the life of the spring. Interleaving liners reduce inter-leaf friction and the squeaking that develops on aged units, and the eyes and centre bolts are dimensioned to a controlled tolerance for clean reassembly into the original mounting arrangement.
Cross-Range Coverage
The range covers the classic MG family. Each spring is rated correctly for the body weight, axle and ride height of the relevant variant, important because GT springs are wound to a higher rate than equivalent Roadster springs, and V8 springs higher again. Fitting the wrong rate produces an incorrect ride height and damper-spring mismatch even if the spring physically locates.
Complete Spring Kits
Alongside individual springs, Q Parts offers complete spring kits for the cars where rear-end refurbishment is most often a single project. Each kit is offered with a choice of standard rubber bushes for owners restoring to original specification, or uprated polyurethane bushes for owners prioritising sharper rear-end response and longer bush life. The polyurethane option holds geometry under cornering loads better than rubber and is the preferred choice for cars used enthusiastically.
Benefit on the Road
A car with fresh standard leaf springs sits at its correct ride height, follows a chosen line cleanly, and absorbs the small, frequent road inputs of UK roads without transferring them to the cabin as harshness. The geometry of the rear suspension is restored, which in turn restores the steering feel and the predictability of the chassis at speed.
Fitment
Q Parts standard leaf springs are produced to the original specification for the relevant car, including length, eye dimensions, leaf count and rate. Installation is a direct replacement using the original shackles, U-bolts and mounting points. Each spring is developed in-house by the MGOC Spares product engineering team, manufactured to specifications that match or exceed original equipment, and supported by the brand's extended warranty programme. The MGOC Spares Q Parts Standard Leaf Spring range encompasses individual interleaving springs and complete spring kits for the classic MG range, with a choice of standard rubber or uprated polyurethane bushes on the kit options, supported by expert technical advice on matching the correct spring to your car.
Owners considering a more comfort-led upgrade should also see the Q Parts Parabolic Leaf Spring range, and owners looking to lower the rear of the car can specify Q Parts Lowering Kits within the wider Suspension & Steering range. The Q Parts range is under active development by the MGOC Spares product engineering team, with new lines added regularly as the brand expands across the engine, cooling, fuelling, suspension, charging, weather equipment and interior categories.
