Built between 1968 and 1971, these models blended American-inspired styling with local engineering and delivered some of the most iconic road cars ever to wear the Holden badge. From Kingswood sedans to Monaro GTS coupes, these cars were designed for comfort first, with handling very much a secondary consideration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fast forward more than 50 years and things have changed. Even well-preserved examples now suffer from tired suspension components, degraded rubber bushes, worn shocks and steering systems that feel vague by modern standards.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The good news? The HK\u2013HT\u2013HG platform responds exceptionally well to suspension upgrades. With the right combination of parts, you can dramatically improve ride quality, handling precision and overall safety without destroying the classic character of the car.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Understanding the Factory Suspension Feel<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Before upgrading, it\u2019s important to understand what you\u2019re starting with.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Factory Characteristics<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Soft spring rates for comfort<\/li>\n\n\n\n<li>Limited cornering control<\/li>\n\n\n\n<li>Significant body roll<\/li>\n\n\n\n<li>Basic shock absorber damping<\/li>\n\n\n\n<li>Rubber bushes designed for isolation, not precision<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When new, this setup was ideal for Australian roads in the late 60s.
