KSP 3inF+2inR Tundra Lift Kits - Front Spacer and Rear Block Leveling

In this review of the KSP 3inF+2inR Tundra Lift Kits the bottom line is simple: it is aimed at Tundra owners who want a reliable, factory-minded way to level and lift their truck up to the specified height without replacing struts. The kit is notable for using forged aircraft-grade aluminum in the front spacers and carbon steel rear blocks with extended U-bolts, which together provide a durable, corrosion-resistant solution; the biggest reason to buy is the combination of solid materials and a design that yields a full 3in front lift effect despite thinner front spacer thickness due to suspension geometry.

Key Features

• Vehicle fit: Designed specifically for 2007-2021 Tundra 2WD and 4WD models, providing a targeted leveling solution for this range of trucks.
• Material quality: Front spacers are forged from aircraft-grade aluminum billet and the rear blocks use carbon steel, giving strength and improved corrosion resistance when powder coated.
• Lift result: Although front spacer thickness is less than 3in, the kit is engineered to raise the truck by 3in overall due to suspension geometry for a level stance.
• Reinforced rear block: Cross gusset plate locked design adds firmer support to the rear block compared with standard blocks, reducing flex under load.
• Hardware and fitment: Includes longer leaf spring U-bolts with 9/16 thread pitch and 10.9 grade, plus 12.9 grade solid bolts up front, to suit higher blocks and provide secure fastening.
• Aftercare: Backed by a 30-day refund and 12-month parts replacement policy to address fit or component issues.

Who It's For

This kit is best for owners of 2007-2021 Toyota Tundra 2WD or 4WD who want a bolt-on leveling and lift solution without replacing the front struts, and who value machined components and heavy-duty hardware. It is especially useful for drivers planning to run larger tires, for example customers who reported gaining clearance for 285/70/16 tires.

It is not suitable for trucks with electric front struts, TRD Pro models, or XSP-X models, so owners of those variants should look elsewhere. Also expect to perform a wheel alignment after installation and be prepared for some DIY skill or professional installation if you are not comfortable with suspension work.

Pros & Cons

Pros

• High-quality materials and machining give a durable, corrosion-resistant finish and dependable fit.
• Provides an effective 3in front lift result despite thinner spacer thickness because of suspension geometry.
• Reinforced rear block and longer, stronger U-bolts improve rear support for higher ride height.
• Good value with a parts replacement warranty for 12 months.

Cons

• Does not fit electric front struts, TRD Pro, or XSP-X models, limiting compatibility.
• Installation instructions may be incomplete for some users, so expect variation in ease of install and possibly the need for professional help.
