The ReadyLift 66-3051 Rear Block Kit will safely add 1" of lift to your 99-10 GM 2500HD/3500HD SRW Pickup. This will add a slight rake back into your truck for hauling or towing. The ReadyLift Block is based on OEM designs and made from heavy-duty cast iron just like the factory blocks. This ensures maximum strength and long-term reliability. Fits Single Rear Wheel (SRW) trucks only.
