Heavy Duty Shift Spring

On Sale! $3.80

Update: Now available for one-piece Land Cruiser Transfer Cases!

This shift spring is an optional upgrade part for your transfer case that provides a stronger engagement and a better overall shift feel. Additionally, by applying more pressure on the shift detent, this spring decreases the chance for an accidental or unintended gear shift.

If your transfer case is popping out of gear on the trail, then this heavy duty spring may help!

On Hilux Pickup/4Runner applications, they are easy to install from the outside without disassembly requiring only a 6mm hex socket and possibly also a small magnet to extract the stock spring. Land Cruiser applications require more work to replace as the low-neutral-high spring is located inside the case.

In general, only (1) spring is required per transfer case, which is always installed for the low-neutral-high shift rail (this is the driver's side spring on Hilux Pickup/4Runner applications). However, it is common to get (2) and replace both springs so that the shifting performance of both patterns is improved as a whole. In other words, "if you are gonna replace one, you might as well replace both!" If you have a dual case Crawl Box, then be sure to pick up an extra spring as Crawl Boxes also use (1) spring.

Be sure to add a thread sealant during reassembly such as Loctite's Hi-Tack Gasket Sealant.

Crossmember Mount, HD

On Sale! $71.25
Installation Notes
Double check the lower four threaded holes with an 8x1.25mm tap to clean out any paint. Installation Notes

As you have probably already discovered, off roading places heavy abuse on many parts of your truck that don't get abused when your truck is driven "normally". One such part is your stock transfer case mount. The stock mount has a soft rubber block and bolts between your transfer case and it's cross member. It has a tendency to do one of two things: 1) Flex to much allowing your shifters to interfere with the cab, or even worse, 2) fatigue and rip in half! Don't get caught in the middle of the trail, in the middle of nowhere, with a transmission & transfer case flopping around!

To help avoid such a situation, Locktup 4x4 has created a heavy duty transfer case mount for Toyota trucks and is providing them to us in powder-coated Marlin Crawler Red! This new design replaces the soft & weak OEM rubber with longer lasting USA-made urethane round bushings. These bushings will not split and fail on you, eliminating such worries associated with stock mounts.

In addition, the mounts are USA-made with thick, high quality USA-steel plates that are laser cut and CNC formed for the best fit & finish possible. The welds are high quality; Not some cheap imported mount!

Another trick feature to this mount: If you need to remove your transfer case or transmission, now you only need to remove the two bolts from the bushings to pull the cross member down! This is much better than having to remove the 4 hard-to-get-to and easy-to-strip bolts that engage in the cross member.

Direct replacement of your 1979-95 gear drive transfer case mounts and 1982-95 4-cylinder cross members. Fully compatible with all aftermarket cross members that use stock t/case mounts. Direct replacement with the same mounting height as the stock mounts. Please note they do not work with chain drive transfer cases such as those found behind automatics and G58 5-speed transmissions.

Crossover Steering Stabilizer

On Sale! $80.10

During a crossover steering conversion, the stock steering stabilizer is discarded. This kit mounts a new heavier duty stabilizer shock between the frame rail and the drag link, which keeps the shock up high and out of the reach of those pesky rocks.

Kit features a larger (9.25" stroke) and stronger shock, drag link mount and weld on frame mount. Frame mount is an assembled block and is easily welded to frame.

This stabilizer can also be mounted to the tie rod in a standard steering configuration (non-crossover). Simply remove the stock steering stabilizer and grind off its mount from the front of your axle and weld the included mount to your axle near the same location (instead of the frame). This is perfect when used with our Heavy Duty Marlink tie rod which lacks a stock steering stabilizer mount provision.

The included u-bolt mount kit is designed to fit a 1.25" steering linkage.

Heavy Duty Knuckle Gusset Kit

Heavy Duty Knuckle Gusset KitHeavy Duty Knuckle Gusset Kit, TopHeavy Duty Knuckle Gusset Kit, Bottom
On Sale! $84.55

This is our new & exciting Heavy Duty Knuckle Gusset Kit! What separates our new Heavy Duty Knuckle Gusset Kit from the rest?

• Full Stop-to-Stop Bracing

In the past, small add-on plates have been used to cap off the steering stop. We've now integrated the knuckle gusset itself with the steering stops.

• Four Braces Instead of Two

In the past we only used single braces on the top and bottom mounted perpendicular to the axle housing. Our new design features four braces to better spread the load and increase load rating.

• Angled Bottom Edge

The sharp edges of the old single perpendicular-mounted bottom brace were just crying for attention from rocks. Our new heavy duty design ramps the two bottom braces with a rounded edge for better functionality + strength.

• Full Ball-to-Spring-Perch Support

The upper plates extend to the spring perch where they are welded for full leaf spring to knuckle support!

• Compatible with Coil Over & Air Shocks

We've left enough room to fit common coil over and air shocks to the upper gusset.

• Made In The USA with High Quality USA Steel

We are a long-time supporter of Made In USA with high quality and long lasting USA steel.

Kit includes enough pieces to install on both sides of a 1979-85 Pickup/4Runner axle housing: one kit fits one truck. More pictures & discussion here!

Bilstein 5100 Ride Height Adjustable Tacoma Front Strut, 2nd Gen

On Sale! $114.00
SKU: MCSU-3412

We are excited to offer Bilstein's 5100-series Adjustable Ride Height Front Struts for your 2005-2014 2WD PreRunner and 4WD Tacoma!

These struts are designed for front coilover suspension systems and feature multiple snap ring grooves to position the spring seat at 0" (stock), 1.25", or 2.50" higher up the strut body than stock. The result is a final ride height front adjustment from 0" to 2.50" higher than stock for improved tire and ground clearances as well as leveling your front with your rear suspension. This is a great alternative to coil spacers because the shock is designed with a full range of operation regardless of the position used.

This is also an inexpensive alternative to a fully threaded type strut body, and features Bilstein's famous monotube design backed by a Lifetime Warranty. Also uses the same self-adjusting deflective disc valving used in every other Bilstein shock we carry for superior ride compliance.

Simply replace your factory strut/shock while maintaining your factory coil spring. Race inspired with an oversized self-adjusting digressive piston and valved specifically for the 1st gen Tacoma. Put Bilstein's high pressure nitrogen gas performance to use in your truck today!

Install notes: Keep in mind that raising or lowering your front suspension will alter its camber, toe, and caster measurements. Therefore we recommend getting your front suspension re-aligned, especially if the ride height changes, and after any successive ride height adjustment. Bilstein does not recommend using these in conjunction with big coil spacers and neither do we. Regardless, the factory upper control arms (UCA) can only take around 2.75 to 3-inches of total lift gain. Any higher and you'll need to run aftermarket UCAs in order to regain the ability to set factory alignment settings.

Sold separately. Qty 2 required per vehicle.
